Ontario trade certification records
One record per trade: the trade code, whether certification is compulsory, whether a certifying exam is required, whether an apprentice to journeyperson ratio applies, and whether the trade carries the Red Seal. All classification facts are read directly from O. Reg. 876/21. All four trade sectors are covered: construction, industrial, motive power and service.
Construction sector trades (41)
Industrial sector trades (40)
Motive power sector trades (19)
Service sector trades (19)

Compulsory status, certifying exam requirement and apprentice ratio for every trade below are read directly from O. Reg. 876/21 as consolidated on e-Laws. Trade codes and apprentice counts come from Ontario's published apprenticeships dataset.
Prescribed trades without a record here (14)
These are prescribed trades under O. Reg. 876/21 with an official trade code, but Ontario publishes nothing describing the work, the training hours or the exam for them, and they are not Red Seal trades. Rather than publish a page that only repeats the trade's name, they are listed here. Check Skilled Trades Ontario for the current position on any of them.

Workplace fatalities and injuries
Ontario publishes worker fatality and critical injury counts by sector rather than by trade. See fatalities and critical injuries in Ontario by sector, 2015 to 2024, with the reporting caveats that come with those numbers.
Looking for the compulsory trades?
23 of Ontario's 144 prescribed trades are compulsory, meaning certification is required by law to work in them. The full list, including trades outside the construction and industrial sectors, is on the compulsory trades in Ontario page.
