## Working at Heights training requirement (Ontario)
URL: https://ontariocertificationregistry.ca/safety-training/working-at-heights/
Also called: WAH, heights ticket, fall protection ticket.
Ontario's only fall-protection training that is both government-approved and time-limited. It is required on construction projects, it expires after three years, and the practical half cannot legally be done online.
Required by law: Yes, on construction projects. An employer must ensure a worker has completed approved working at heights training before the worker may use a travel restraint system, a fall restricting system, a fall arrest system, a safety net, a work belt or a safety belt on a project. Source: O. Reg. 297/13, ss. 6 and 7 (1).
Government-approved provider required: Yes, both the program and the provider. The program must be approved by the Chief Prevention Officer against the working at heights training program standard in force at the time of the training, and it must be delivered by a provider separately approved by the Chief Prevention Officer against the provider standard. Source: O. Reg. 297/13, s. 7 (2), paras. 1 and 2.
Expiry: Three years. Training is valid for three years from the date of successful completion. Refresher training re-validates it for another three years. Source: O. Reg. 297/13, s. 8 (1).
Training length: 6.5 hours minimum. Two modules: Working at Heights Basic Theory, minimum three hours, and Working at Heights Practical, minimum three and a half hours. A provider may run longer. The maximum ratio for face-to-face delivery is twelve learners to one instructor. Source: Working at Heights Training Program Standard, s. 6.1.
Verification: Yes, through the ministry. An employer can accept a proof of completion issued by the Chief Prevention Officer or an approved provider, look the worker's record up with the worker's consent through the ministry's certification management system, or contact the ministry directly with the worker's consent.
Refresher: Refresher training is the Working at Heights Practical module on its own, delivered by an approved provider. Passing it re-validates the training for a further three years. A worker must already have completed both modules of an approved program to be eligible.
Must be covered: Roles, rights and responsibilities for working at heights under the Occupational Health and Safety Act; General hazard recognition for working at heights; The hierarchy of controls; Safety procedures for warning methods and physical barriers; Practical use of the fall protection equipment the worker will actually use.
Employer must keep: A copy of the worker's proof of completion document, or; A record showing the worker's name, the approved training provider's name, the name of the approved program, and the date the training was successfully completed.
Note - A fully online working at heights course is not valid: The program standard permits eLearning for the Basic Theory module only, and only where it includes interactivity with a qualified instructor. It states plainly that eLearning is not an acceptable delivery method for the Practical module. Any course offering the whole ticket online does not meet the standard. Source: Working at Heights Training Program Standard, s. 6.2.
Note - The ministry is currently warning about fraudulent training cards: Ontario has an active alert about fake working at heights training cards in circulation. This is why the province publishes both a searchable provider list and a record lookup, and why an employer should verify the record rather than accept a card at face value. Source: Ministry of Labour, Immigration, Training and Skills Development.
Note - Verify the provider was approved on the day the worker trained: Approval is not permanent. A provider that has since been removed from the approved list still delivered valid training while it was approved, and a provider approved today did not necessarily deliver valid training two years ago. The check is against the date on the record. Source: Ministry of Labour, Immigration, Training and Skills Development.
Note - Training completed in one narrow 2017 window lasts four years, not three: Working at heights training successfully completed between 28 February 2017 and 31 August 2017 is valid for four years rather than three. This was a transitional measure and it still sits in the regulation. Source: O. Reg. 297/13, s. 8 (2).
Note - Newfoundland and Labrador fall protection training is accepted: A worker holding fall protection training prescribed under s. 139 of the Occupational Health and Safety Regulations, 2012 of Newfoundland and Labrador satisfies the requirement in Ontario. It stays valid until the expiry date printed on the WorkplaceNL certificate of completion. Source: O. Reg. 297/13, ss. 7 (1) (b) and 8 (3).
Note - Automobile manufacturing workplaces are exempt: The requirement does not apply to a worker directly employed by an automobile manufacturer working on a project at that employer's own automobile manufacturing, marshalling, parts manufacturing, parts warehousing or research and development workplace. The regulation defines each of those five terms. Source: O. Reg. 297/13, ss. 7 (3) and 7 (4).
Note - The ticket alone is not enough: O. Reg. 213/91 s. 26.2 applies on top of the working at heights ticket. The employer must also ensure the worker is adequately trained on the specific fall protection system being used and given oral and written instructions by a competent person, and the trainer must sign a written record naming the worker and the dates. Source: O. Reg. 297/13, s. 9; O. Reg. 213/91, s. 26.2.
Note - It travels with the worker, not the employer: A worker changing employers does not have to retake the program while the training is still valid. Source: Ministry of Labour, Immigration, Training and Skills Development.

## JHSC Certification training requirement (Ontario)
URL: https://ontariocertificationregistry.ca/safety-training/jhsc-certification/
Also called: JHSC, certified member training, Part 1 and Part 2.
The training that makes a committee member a certified member. Two parts plus a refresher, all government-approved, valid three years, and the employer is expressly required to pay for it.
Required by law: Yes, for at least two committee members. Most workplaces with twenty or more workers must have a joint health and safety committee. At least one worker member and at least one employer member on that committee must be certified. The employer must carry out the training needed to get them there. Source: Occupational Health and Safety Act, s. 9; O. Reg. 297/13, s. 5 (1).
Government-approved provider required: Yes. The program must be approved by the Chief Prevention Officer against both the JHSC certification training program standard and the training provider standard. Certification itself is issued by the Chief Prevention Officer. Source: O. Reg. 297/13, s. 5 (1).
Expiry: Three years. Certification is valid for three years after successfully completing Part Two. A refresher within three years of certification, or of the last refresher, keeps it valid. Source: Ministry of Labour, Immigration, Training and Skills Development.
Training length: Six days across Part One and Part Two. Part One is three days, or 19.5 hours. Part Two is two days, or 13 hours. The refresher is one day, or 6.5 hours. Class size must normally be between six and twenty-five learners. Source: JHSC Certification Training Program Standard, s. 6.1.
Verification: Yes, through the ministry. A worker must hold a valid certification record issued by the Chief Prevention Officer. An employer can accept that record, look it up with the worker's consent through the ministry's certification management system, or contact the ministry to confirm it.
Refresher: One day, 6.5 hours, delivered by an approved provider. It must be completed within three years of certification or of the previous refresher, and both Part One and Part Two must already be complete.
Must be covered: Part One covers the general health and safety knowledge a committee member needs, including the Act, rights and duties, and hazard recognition; Part Two is workplace-specific and covers the hazards actually present at the learner's workplace; The refresher maintains the knowledge from both parts.
Employer must keep: Proof of each worker's JHSC certification, made available to a ministry inspector on request.
Note - The employer must pay for it, and the regulation says so outright: The regulation defines the employer's duty to carry out the training and then adds, for greater certainty, that carrying it out includes paying for it. This is unusually explicit and it removes the usual argument about who covers the cost. Source: O. Reg. 297/13, s. 5 (2).
Note - Certification under the 1996 standards never expires: A member certified under the 1996 standards set by the Workplace Safety and Insurance Board does not have to take refresher training at all. The three-year cycle applies to certifications issued under the current standards. Source: Ministry of Labour, Immigration, Training and Skills Development.
Note - There is a one-time extension if you are about to lapse: An active certified member whose certification is about to expire may apply once to the Chief Prevention Officer for a three-year extension without taking the refresher. The request has to be approved before the certification expires, not after. Source: Ministry of Labour, Immigration, Training and Skills Development.
Note - Refresher eligibility requires both parts: A worker who completed Part One but never Part Two is not eligible for refresher training. The ministry publishes an eligibility checker for this. Source: Ministry of Labour, Immigration, Training and Skills Development.
Note - Certification training is not the same as job training: The program standard draws the line explicitly: certification training is separate from the job-specific health and safety training an employer already has to provide under the Act and its regulations. Certifying a member does not discharge any other training duty. Source: JHSC Certification Training Program Standard.
Note - The Distance Learning Standard was revoked: The separate JHSC Certification Distance Learning Standard announced on 1 June 2020 was revoked. Since 30 June 2021 the distance requirements sit inside the main program and provider standards. Providers approved under the old standard did not have to reapply. Source: Ministry of Labour, Immigration, Training and Skills Development.
Note - The old regulation is long gone: O. Reg. 780/94, Training Programs, which used to govern certification training, was revoked on 14 November 2013 by O. Reg. 297/13. Anything still citing it is out of date. Source: O. Reg. 780/94, revocation note.

## WHMIS training requirement (Ontario)
URL: https://ontariocertificationregistry.ca/safety-training/whmis/
Also called: Workplace Hazardous Materials Information System, hazardous products training.
Required for anyone who works with or near a hazardous product. There is no expiry date anywhere in Ontario law, and no approved provider list. What the law actually requires is a review at least once a year.
Required by law: Yes, if hazardous products are present. An employer must inform every worker who works with, or may be exposed to, a hazardous product about the hazard information the employer has or ought to have, and must instruct them on six prescribed subjects. Source: R.R.O. 1990, Reg. 860, ss. 6 and 7 (1).
Government-approved provider required: No. Ontario does not approve WHMIS training providers or programs. Anyone competent can deliver it, including the employer, provided the instruction covers the prescribed subjects and is specific to the workplace. Source: R.R.O. 1990, Reg. 860, s. 7 (2).
Expiry: None in Ontario law. Neither Regulation 860 nor the Act sets any expiry date, renewal period or validity term for WHMIS training. A three-year WHMIS card is a training provider's own policy, not a legal requirement. Source: R.R.O. 1990, Reg. 860.
Training length: Not prescribed. Ontario sets no minimum course length for WHMIS. It sets the subjects that must be covered and the outcome that must be achieved. Source: R.R.O. 1990, Reg. 860, s. 7.
Verification: No public registry. There is no government WHMIS registry and no ministry-issued record. Verification is the employer's own record keeping.
Refresher: There is no refresher course in Ontario law. There is an annual review duty under s. 42 (3) of the Act, carried out with the joint health and safety committee, which looks at both the training and how familiar the worker actually is with it.
Must be covered: What must be on a label, and the purpose and significance of that information; What must be on a safety data sheet, and the purpose and significance of that information; Procedures for safe use, storage, handling and disposal of a hazardous product; Procedures for a hazardous product contained or transferred in a pipe, piping system including valves, process vessel, reaction vessel, tank car, tank truck, ore car, conveyor belt or similar conveyance; Procedures to follow when fugitive emissions are present; Procedures to follow in an emergency involving a hazardous product.
Employer must keep: No specific record is prescribed by Regulation 860, but the employer must be able to show the instruction was given and reviewed.
Note - The real requirement is annual, not three-yearly: The Act requires an employer to review the training and instruction given to a worker, and the worker's familiarity with it, in consultation with the joint health and safety committee or health and safety representative, at least annually. That is a more frequent duty than the three-year card most vendors sell, not a less frequent one. Buying a new card every three years does not satisfy it. Source: Occupational Health and Safety Act, s. 42 (3).
Note - And more often when something changes: The review must happen more frequently than annually if the employer determines it is necessary on the advice of the committee or representative, or if there is a change in circumstances that may affect a worker's health or safety. A new product, a new process or a new job assignment is such a change. Source: Occupational Health and Safety Act, s. 42 (4).
Note - Generic online WHMIS does not finish the job: The regulation requires the program of worker education to be developed and implemented for that employer's workplace and to be related to the other training and prevention programs there. A generic course covering pictograms and safety data sheets in the abstract does not cover the products actually in the building. Source: R.R.O. 1990, Reg. 860, s. 7 (2).
Note - The test is whether workers can use it, not whether they sat through it: The employer must ensure, so far as is reasonably practicable, that the instruction results in workers being able to use the information to protect their own health and safety. A completion certificate is evidence, not compliance. Source: R.R.O. 1990, Reg. 860, s. 7 (3).
Note - The training must be built with the committee: Instruction and training on hazardous materials must be developed and implemented in consultation with the joint health and safety committee or the health and safety representative. It is not something the employer designs alone. Source: Occupational Health and Safety Act, s. 42 (2).
Note - Basic awareness training already includes a WHMIS component: The mandatory worker awareness program must cover the requirements of Regulation 860 with respect to information and instruction on hazardous products. That is an overview, not a substitute for workplace-specific WHMIS instruction. Source: O. Reg. 297/13, s. 1 (3), para. 6.

## Confined Space Entry training requirement (Ontario)
URL: https://ontariocertificationregistry.ca/safety-training/confined-space/
Also called: confined space entry training, confined space ticket.
Two different training duties depending on whether the workplace is a construction project. No expiry, no approved provider, but a mandatory annual review and a stack of surrounding duties that no ticket covers.
Required by law: Yes. Every worker who enters a confined space or performs related work must be given adequate training for safe work practices in confined spaces, including training in recognising the hazards, and separately must receive training specific to the written plan for that space. Source: O. Reg. 632/05, ss. 8 (1) and 9 (1).
Government-approved provider required: No. Ontario does not approve confined space training providers or programs. The employer must appoint a person with adequate knowledge, training and experience to conduct the training. Source: O. Reg. 632/05, s. 8 (2).
Expiry: None in Ontario law. The regulation sets no expiry date and no renewal period. It sets a review duty instead. Source: O. Reg. 632/05.
Training length: Not prescribed. Ontario sets no minimum course length for confined space training. The standard is adequacy, judged against the plan for the specific space. Source: O. Reg. 632/05, s. 8.
Verification: No public registry. There is no government confined space registry. The employer must keep up-to-date written records showing who provided the training, who received it, the nature of the training and the date.
Refresher: There is no refresher course in Ontario law. There is an annual review duty under s. 8 (4), carried out with the joint health and safety committee, plus a review whenever circumstances change.
Must be covered: Safe work practices for working in confined spaces and for performing related work; Recognition of the hazards associated with confined spaces; The content of the written plan for the specific confined space the worker will enter.
Employer must keep: Up-to-date written records showing who provided the training, who received it, the nature of the training and the date it was provided; These records may be incorporated into the entry permit for the space.
Note - Construction projects follow a different section: Sections 8 and 9, the hazard recognition and plan-specific training duties, expressly do not apply to workplaces that are projects. Construction projects are governed by section 9.1 instead. A course written for an industrial plant is not automatically the right course for a jobsite. Source: O. Reg. 632/05, ss. 8 (0.1), 9 (0.1) and 9.1.
Note - It has to be reviewed at least once a year: The employer must review the training in consultation with the joint health and safety committee or health and safety representative whenever there is a change in circumstances that may affect the safety of a worker entering a confined space, and in any case at least once annually. Source: O. Reg. 632/05, s. 8 (4).
Note - There are two separate trainings, not one: General hazard recognition training under section 8 and plan-specific training under section 9 are distinct duties. They may be combined in delivery, but both have to happen, and the plan-specific part changes every time the space or the plan changes. Source: O. Reg. 632/05, ss. 8 (7) and 9 (4).
Note - The ticket is the smallest part of the obligation: A confined space entry also requires a written program, a hazard assessment, a written plan, an entry permit, on-site rescue procedures, rescue equipment and a means of communication, isolation of energy and material movement, an attendant stationed outside, controlled means of entry and exit, prevention of unauthorised entry, and atmospheric testing. Training alone does not make an entry lawful. Source: O. Reg. 632/05, ss. 5 to 18.

## Asbestos Abatement training requirement (Ontario)
URL: https://ontariocertificationregistry.ca/safety-training/asbestos/
Also called: asbestos abatement worker training, asbestos awareness, Type 3 training.
Ontario's third government-approved safety credential, and the only one tied to a provincial medical register. Type 3 work needs a ministry-approved program; Type 1 and 2 work needs instruction from a competent person.
Required by law: Yes, in tiers. Every worker in a Type 1, Type 2 or Type 3 operation must receive instruction and training from a competent person on the hazards of asbestos exposure, personal hygiene and work practices, and the use, cleaning and disposal of respirators and protective clothing. Type 3 work carries a further, much stricter requirement. Source: O. Reg. 278/05, s. 19 (1).
Government-approved provider required: Yes, for Type 3 work only. Every worker involved in a Type 3 operation must have successfully completed the approved Asbestos Abatement Worker Training Program, and every supervisor of such a worker must have completed the approved Asbestos Abatement Supervisor Training Program. Both are approved by the provincial ministry responsible for advanced education and skills development. Source: O. Reg. 278/05, s. 20 (1).
Expiry: None stated in the regulation. O. Reg. 278/05 sets no expiry date on either the Type 1 and 2 instruction or the approved Type 3 programs. The annual duty here is the asbestos work report, not a training renewal. Source: O. Reg. 278/05.
Training length: Set by the approved program. The regulation itself prescribes no course length. Length is fixed by the approved Asbestos Abatement Worker and Supervisor Training Programs. Source: O. Reg. 278/05, s. 20.
Verification: Yes, for Type 3 work. A document issued by the ministry showing successful completion of an approved program is conclusive proof of that completion for the purposes of the regulation.
Refresher: The regulation prescribes no refresher training. It prescribes an asbestos work report at least once every twelve months for every Type 2 and Type 3 worker, and voluntary medical surveillance through the Asbestos Workers Register.
Must be covered: The hazards of asbestos exposure; Personal hygiene and work practices; The use, cleaning and disposal of respirators and protective clothing; For Type 3 work, the full approved Asbestos Abatement Worker or Supervisor Training Program.
Employer must keep: An asbestos work report for each Type 2 and Type 3 worker, at least once every twelve months and immediately when the worker's employment ends; The report goes to the Provincial Physician at the ministry, with a copy to the worker.
Note - Training has to come before the work, not during it: The employer must ensure the worker or supervisor has successfully completed the required program before performing or supervising the work it relates to. There is no learning on the job for Type 3 asbestos work. Source: O. Reg. 278/05, s. 20 (2).
Note - There is a provincial Asbestos Workers Register: The Provincial Physician maintains a register listing every worker for whom an employer files an asbestos work report. A worker on the register may volunteer, on the Provincial Physician's recommendation, for a prescribed medical examination consisting of a medical questionnaire, chest x-rays and pulmonary function tests, with follow-up examinations at least five years apart. Source: O. Reg. 278/05, s. 22.
Note - Building owners have their own separate training duty: The owner of a building containing asbestos must establish and maintain a training and instruction program for every worker the owner employs who may disturb that material, covering the hazards of exposure, protective equipment and clothing, personal hygiene, and the prescribed measures and procedures. This is separate from the contractor's duty. Source: O. Reg. 278/05, s. 8.
Note - The tier decides everything: Type 1, Type 2 and Type 3 are defined by the operation, not by the worker. The same person can need only competent-person instruction on Monday and an approved ministry program on Tuesday, depending on what the work is. Classify the operation first. Source: O. Reg. 278/05, s. 12.

## Lift Truck Operation training requirement (Ontario)
URL: https://ontariocertificationregistry.ca/safety-training/forklift/
Also called: forklift licence, forklift certification, lift truck ticket.
There is no forklift licence in Ontario. No prescribed course, no card, no expiry, no approved provider and no government registry. What the law requires is a competent person, and it defines exactly what that means.
Required by law: Competence is required; a course is not prescribed. Mobile equipment, which includes a lift truck, shall be operated only by a competent person. The Act then defines a competent person in three parts, and training is one of them. Source: R.R.O. 1990, Reg. 851, s. 54 (1) (d); Occupational Health and Safety Act, s. 1.
Government-approved provider required: No. Ontario approves no forklift training providers and no forklift programs. There is no government standard for the content or the length of a forklift course. Source: R.R.O. 1990, Reg. 851.
Expiry: None in Ontario law. Because there is no prescribed certificate, there is nothing to expire. The three-year renewal cycle sold with most forklift cards is the training provider's own policy. Source: R.R.O. 1990, Reg. 851.
Training length: Not prescribed. Ontario sets no minimum hours. The standard is competence, judged against the definition in the Act and the specific equipment and workplace. Source: Occupational Health and Safety Act, s. 1.
Verification: No public registry. There is no ministry lookup for forklift operators. Whatever record exists is the employer's own.
Refresher: Ontario law prescribes no forklift refresher. The employer's obligation is continuous: the operator must be a competent person every time they operate the equipment, which means retraining when the equipment, the workplace or the hazards change.
Must be covered: Whatever is needed for the operator to meet the statutory definition of a competent person for that equipment in that workplace.
Employer must keep: No record is prescribed for forklift training specifically, but the employer must be able to demonstrate the operator is a competent person.
Note - What a competent person actually means: The Act defines a competent person as someone who is qualified because of knowledge, training and experience to organize the work and its performance, is familiar with the Act and the regulations that apply to the work, and has knowledge of any potential or actual danger to health or safety in the workplace. All three limbs, not just the first. Source: Occupational Health and Safety Act, s. 1.
Note - A trainee may operate one, under supervision: The competent person requirement does not apply to mobile equipment operated by a worker while the worker is being instructed and accompanied by a competent person. That is the lawful route for a new operator, and it requires the trainer to be physically with them. Source: R.R.O. 1990, Reg. 851, s. 54 (2).
Note - A card from a course is evidence, not compliance: Because the law asks for competence rather than a certificate, a wallet card proves a course was taken. It does not by itself prove the operator is familiar with this workplace, this machine and the hazards actually present, which is what the definition requires. Source: Occupational Health and Safety Act, s. 1.
Note - The general training duty still applies: Separately from the competent person rule, an employer must provide information, instruction and supervision to a worker to protect their health and safety. That duty covers forklift operation whether or not any course is taken. Source: Occupational Health and Safety Act, s. 25 (2) (a).
Note - Using one to lift a person is heavily restricted: A lift truck may be used to support, raise or lower a worker only in tightly defined conditions, including a platform with automatic fall protection, a load under half the maximum rated capacity where the equipment was not designed to hoist people, and a sign on the platform stating the permitted load. Source: R.R.O. 1990, Reg. 851, s. 52.

## Traffic Control Person training requirement (Ontario)
URL: https://ontariocertificationregistry.ca/safety-training/traffic-control-person/
Also called: TCP, flagger, traffic control, road traffic controller.
No licence and no prescribed course, but two hard limits that stop the work outright, a sign specified to the millimetre, and written instructions that must stay on the project.
Required by law: Competence plus written and oral instructions. A worker required to direct vehicular traffic must be a competent worker, must not perform any other work while doing it, must be positioned so as to be endangered as little as possible, and must be given adequate written and oral instructions in a language they understand, including a description of the signals to be used. Source: O. Reg. 213/91, s. 69 (4).
Government-approved provider required: No. Ontario approves no traffic control person training providers or programs. Book 7 of the Ontario Traffic Manual is a Ministry of Transportation guidance document, not a regulation, and completing a course based on it is not a legal requirement in itself. Source: O. Reg. 213/91, s. 69.
Expiry: None in Ontario law. There is no prescribed certificate, so there is nothing to expire. Any expiry date on a traffic control card comes from the training provider or the contract, not the regulation. Source: O. Reg. 213/91.
Training length: Not prescribed. Ontario sets no minimum hours. The requirement is adequacy of the instructions and competence of the worker. Source: O. Reg. 213/91, s. 69 (4).
Verification: No public registry. There is no ministry lookup. What must exist on the project is the written instructions given to the worker.
Refresher: Ontario law prescribes no refresher. The instructions must be adequate and current for the project the worker is on, which in practice means new written instructions for a new traffic protection plan.
Must be covered: A description of the signals the worker is to use; The employer's traffic protection plan for the project; Correct positioning relative to traffic.
Employer must keep: The written instructions given to the worker, kept at the project; A written traffic protection plan, kept at the project and made available to an inspector or a worker on request.
Note - Never more than one lane in the same direction: A worker shall not direct vehicular traffic for more than one lane in the same direction. This is an absolute limit and no amount of training changes it. Source: O. Reg. 213/91, s. 69 (2).
Note - Never above a 90 km/h posted limit: A worker shall not direct vehicular traffic if the normal posted speed limit of the public way is more than 90 kilometres per hour. Above that, traffic must be managed some other way. Source: O. Reg. 213/91, s. 69 (3).
Note - The sign is specified to the millimetre: The sign must be octagonal, 450 millimetres between opposite sides, on a pole 1.2 metres long, made of material at least as rigid as six millimetre plywood. One side is high-intensity retro-reflective red with STOP in high-intensity retro-reflective white letters 150 millimetres high. The other is high-intensity retro-reflective micro-prismatic fluorescent chartreuse with a black diamond border at least 317 by 317 millimetres and SLOW in black letters 120 millimetres high. It must be kept clean and legible. Source: O. Reg. 213/91, s. 68.
Note - Directing traffic must be the only job: The worker shall not perform any other work while directing traffic. The same rule applies to a worker setting up or removing traffic protection measures on a roadway or shoulder. Source: O. Reg. 213/91, ss. 69 (4) (b) and 67 (6) (b).
Note - A written traffic protection plan is mandatory: Every employer must develop in writing and implement a traffic protection plan for its workers at a project where any of them may be exposed to a hazard from vehicular traffic. It must specify the hazards and the protective measures used, and be kept at the project. Source: O. Reg. 213/91, ss. 67 (4) and 67 (5).
Note - Signalling for equipment is a different duty: A signaller assisting a vehicle or machine operator whose view is obstructed is a separate role with its own requirements: adequate oral training in the duties, adequate oral and written instructions in a language the worker understands, the written instructions kept at the project, and procedures established jointly with the operator. Source: O. Reg. 213/91, s. 106.
Note - Barriers, not people, on longer freeway jobs: Adequate barriers must be installed to protect workers where the project is on a freeway, is not a mobile operation, and is expected to take more than five days. Where barriers are impractical, or the job is five days or less, crash trucks must be positioned instead. Source: O. Reg. 213/91, ss. 67 (7) and 67 (10).

## Elevating Work Platform training requirement (Ontario)
URL: https://ontariocertificationregistry.ca/safety-training/elevating-work-platform/
Also called: scissor lift certification, boom lift training, aerial work platform, EWP.
No licence and no expiry, but a requirement most operators do not know about: the training is tied to the class of platform, and it must include a hands-on demonstration before first use.
Required by law: Yes, before first use. A worker who operates an elevating work platform shall, before using it for the first time, be given oral and written instruction on the operation and be trained to operate that class of elevating work platform. Source: O. Reg. 213/91, s. 147 (1).
Government-approved provider required: No. Ontario approves no elevating work platform training providers or programs. The regulation prescribes the content instead of the provider. Source: O. Reg. 213/91, s. 147.
Expiry: None in Ontario law. The regulation sets no expiry and no renewal period. The trigger is the class of machine, not the calendar: a new class means new training. Source: O. Reg. 213/91, s. 147 (1).
Training length: Not prescribed. Ontario sets no minimum hours. It prescribes what the instruction must include, including a hands-on demonstration. Source: O. Reg. 213/91, s. 147 (2).
Verification: No public registry. There is no ministry lookup for elevating work platform operators.
Refresher: Ontario law prescribes no refresher. The requirement re-triggers when the worker moves to a different class of elevating work platform.
Must be covered: The manufacturer's instruction; Instruction in the load limitations; Instruction in, and a hands-on demonstration of, the proper operation of the elevating work platform.
Employer must keep: No record is prescribed by s. 147 itself, but the employer must be able to show the instruction and training were given before first use.
Note - The training is per class of platform: Training on one class of elevating work platform does not carry over to another. A worker trained on a scissor lift has not, by that fact, been trained on a boom lift. Source: O. Reg. 213/91, s. 147 (1).
Note - Oral instruction alone is not enough: The regulation requires both oral and written instruction on the operation. A verbal walkthrough on the morning of the job does not meet it. Source: O. Reg. 213/91, s. 147 (1).
Note - A hands-on demonstration is mandatory: The instruction must include a hands-on demonstration of the proper operation of the platform. This is one of the reasons a purely online course cannot complete the requirement. Source: O. Reg. 213/91, s. 147 (2) (c).
Note - Fall protection usually applies on top: Where a fall protection system is used on the platform, the working at heights training requirement and the fall protection system training under s. 26.2 apply in addition to the platform training. Source: O. Reg. 213/91, s. 26.2; O. Reg. 297/13, s. 7.

## Worker Health and Safety Awareness training requirement (Ontario)
URL: https://ontariocertificationregistry.ca/safety-training/worker-awareness/
Also called: worker awareness training, basic OHS awareness, Worker Health and Safety Awareness in 4 Steps.
The one piece of training every worker in Ontario must have, whatever the job. Seven prescribed topics, no expiry, no approved provider, and it moves with the worker between employers.
Required by law: Yes, for every worker. An employer shall ensure that a worker who performs work for the employer completes a basic occupational health and safety awareness training program as soon as practicable. Source: O. Reg. 297/13, s. 1 (1).
Government-approved provider required: No. Ontario approves no providers for awareness training. The regulation prescribes the seven topics, and the ministry publishes free workbooks and eLearning that meet them. Source: O. Reg. 297/13, s. 1 (3).
Expiry: None in Ontario law. The regulation sets no expiry and no refresher for basic awareness training. Once it is done and proof exists, it stands. Source: O. Reg. 297/13, s. 1.
Training length: Not prescribed. Ontario sets no minimum hours. The requirement is that the program covers all seven prescribed topics. Source: O. Reg. 297/13, s. 1 (3).
Verification: Employer records only. There is no government registry. The employer must maintain a record of the training completed by its workers and supervisors.
Refresher: There is no refresher for awareness training in Ontario law. Job-specific training duties, including the annual review of hazardous materials training under s. 42 (3) of the Act, are separate.
Must be covered: The duties and rights of workers under the Act; The duties of employers and supervisors under the Act; The roles of health and safety representatives and joint health and safety committees under the Act; The roles of the Ministry, the Workplace Safety and Insurance Board and entities designated under s. 22.5 of the Act; Common workplace hazards; The requirements of Regulation 860 (WHMIS) for information and instruction on hazardous products; Occupational illness, including latency.
Employer must keep: A record of the awareness training completed by each worker and supervisor; A record of anyone the employer is exempt for; Written proof of completion, given to the worker on request.
Note - It is portable, and the new employer must verify it: A worker who has already completed awareness training and gives the new employer proof does not have to retake it, but only if that employer verifies the previous training covered all seven prescribed topics. Accepting the certificate without checking the content does not satisfy the exemption. Source: O. Reg. 297/13, s. 1 (2).
Note - Proof survives the job by six months: If a worker or supervisor asks for written proof of completion within six months of no longer working for the employer, the employer must still provide it. Keep the records after the worker leaves. Source: O. Reg. 297/13, s. 4 (5).
Note - Occupational illness and latency was added later: The seventh topic, occupational illness including latency, was added by O. Reg. 191/19. A program written before that amendment may cover only six topics and will not meet the current requirement. Source: O. Reg. 297/13, s. 1 (3), para. 7.
Note - As soon as practicable means before the hazards, not before the paperwork: The regulation sets no fixed deadline for workers, unlike the one-week rule for supervisors. It requires completion as soon as practicable, which for a worker starting on a hazardous site is measured in hours, not weeks. Source: O. Reg. 297/13, s. 1 (1).

## Supervisor Health and Safety Awareness training requirement (Ontario)
URL: https://ontariocertificationregistry.ca/safety-training/supervisor-awareness/
Also called: supervisor awareness training, Supervisor Health and Safety Awareness in 5 Steps.
A different program from the worker version, with a hard one-week deadline and its own six topics. There is also a grandfather clause that still applies to supervisors who were in the role before 2014.
Required by law: Yes, within one week. An employer shall ensure that a supervisor who performs work for the employer completes a basic occupational health and safety awareness training program for supervisors within one week of performing work as a supervisor. Source: O. Reg. 297/13, s. 2 (1).
Government-approved provider required: No. Ontario approves no providers for supervisor awareness training. The regulation prescribes six topics, and the ministry publishes free materials that meet them. Source: O. Reg. 297/13, s. 2 (3).
Expiry: None in Ontario law. The regulation sets no expiry and no refresher for supervisor awareness training. Source: O. Reg. 297/13, s. 2.
Training length: Not prescribed. Ontario sets no minimum hours. The requirement is coverage of all six prescribed topics inside the one-week window. Source: O. Reg. 297/13, s. 2 (3).
Verification: Employer records only. There is no government registry. The employer must maintain a record, and must provide written proof of completion, or of exemption, on request.
Refresher: There is no refresher for supervisor awareness training in Ontario law.
Must be covered: The duties and rights of workers under the Act; The duties of employers and supervisors under the Act; The roles of health and safety representatives and joint health and safety committees under the Act; The roles of the Ministry, the Workplace Safety and Insurance Board and entities designated under s. 22.5 of the Act; How to recognize, assess and control workplace hazards, and evaluate those controls; Sources of information on occupational health and safety.
Employer must keep: A record of the supervisor awareness training completed; A record of any supervisor the employer is exempt for under the grandfather clause; Written proof of completion or of exemption, given to the supervisor on request.
Note - One week is a hard deadline, unlike the worker rule: Workers must complete awareness training as soon as practicable. Supervisors must complete theirs within one week of first performing supervisory work. A new supervisor promoted on Monday is out of compliance the following Monday. Source: O. Reg. 297/13, ss. 1 (1) and 2 (1).
Note - The supervisor topics are not the worker topics: Four topics overlap, but the supervisor program replaces common workplace hazards, WHMIS requirements and occupational illness with how to recognize, assess and control hazards and evaluate those controls, plus where to find health and safety information. Sending a supervisor through the worker course does not satisfy s. 2. Source: O. Reg. 297/13, ss. 1 (3) and 2 (3).
Note - A grandfather clause still runs from 2014: The worker awareness requirement does not apply to a supervisor who was already supervising for that employer before the regulation came into force, provided the employer verifies they had completed a program meeting the supervisor requirements. That exemption is portable: a later employer can rely on it if the supervisor provides proof. Source: O. Reg. 297/13, ss. 3 (1) and 3 (2).
Note - Awareness training does not make someone a competent person: The Act's definition of a competent person requires knowledge, training and experience to organize the work, familiarity with the Act and applicable regulations, and knowledge of the actual dangers present. A one-hour awareness module does not establish that on its own. Source: Occupational Health and Safety Act, s. 1.

## Lockout and Tagout training requirement (Ontario)
URL: https://ontariocertificationregistry.ca/safety-training/lockout-tagout/
Also called: LOTO, lockout training, energy isolation.
The words lockout and tagout appear nowhere in Ontario's Act or its main workplace regulations. There is no certificate and nothing to expire. What the law does prescribe is the procedure itself, and for electrical work it prescribes what has to be written on the tag.
Required by law: The procedure is required; a course is not prescribed. Where starting a machine, transmission machinery, device or thing may endanger a worker, control switches or other control mechanisms shall be locked out and other effective precautions taken. Cleaning, oiling, adjusting, repairing or maintaining a part is permitted only when dangerous motion has stopped and any part that could subsequently move has been blocked. Source: R.R.O. 1990, Reg. 851, ss. 75 and 76.
Government-approved provider required: No. There is no approved provider list because there is no prescribed lockout or tagout training program in Ontario law. CSA Z460 is a voluntary standard, not a regulation, unless a workplace has adopted it. Source: R.R.O. 1990, Reg. 851.
Expiry: Nothing to expire. There is no lockout or tagout certificate in Ontario law, so no expiry date exists in the regulation. Any renewal cycle on a LOTO card comes from the training provider or the site's own rules. Source: R.R.O. 1990, Reg. 851.
Training length: Not prescribed. Ontario sets no course length because it prescribes no course. The general duty to provide information, instruction and supervision applies. Source: Occupational Health and Safety Act, s. 25 (2) (a).
Verification: No public registry. There is no ministry lookup. What must exist is the employer's written procedures for electrical lockout under s. 42 (7).
Refresher: Ontario law prescribes no lockout or tagout refresher because it prescribes no course. What must stay current is the employer's written electrical lockout procedure and the workers' instruction in it.
Must be covered: The employer's written lockout procedures for electrical work; Blocking of parts that may move after motion has stopped; Communication of the purpose and status of a lockout where more than one worker is involved.
Employer must keep: Written procedures for compliance with the electrical lockout requirements in s. 42.
Note - Electrical work has its own stricter rule: The power supply to electrical installations, equipment or conductors must be disconnected, locked out of service and tagged before and during any work on or near live exposed parts. Each worker must independently determine that this has been done before starting. Source: R.R.O. 1990, Reg. 851, ss. 42 (1) and 42 (2).
Note - The tag's contents are prescribed: Where a tag is used to communicate, it must be made of non-conducting material, be secured against inadvertent removal, be placed in a conspicuous location, state the reason the switch is disconnected and locked out, show the name of the worker who did it, and show the date. Source: R.R.O. 1990, Reg. 851, s. 42 (6).
Note - Written procedures are mandatory for electrical lockout: The employer must establish and implement written procedures for compliance with the electrical lockout section. This is the closest thing Ontario has to a mandatory LOTO program, and it is a document duty rather than a training duty. Source: R.R.O. 1990, Reg. 851, s. 42 (7).
Note - Multi-worker lockouts require communication: Where more than one worker is involved, the worker who disconnected and locked out the power supply must communicate the purpose and status of the disconnection and lockout to the others. Source: R.R.O. 1990, Reg. 851, s. 42 (5).
Note - There are narrow exemptions from locking out: Locking out is not required in defined circumstances, and where the exemption relies on alternative procedures ensuring the circuit is not inadvertently energized, the employer must ensure those procedures are actually carried out. Source: R.R.O. 1990, Reg. 851, ss. 42 (3) and 42 (4).
