The Building Opportunities in the Skilled Trades Act, 2021 has resulted in significant changes to the trades registration system in Ontario. One of the biggest changes is that Skilled Trades Ontario will not be operating on a membership model. To practice a compulsory trade in Ontario you will need to have a valid Registered Training Agreement, Provisional Certificate of Qualification or Certificate of Qualification. Only the information for individuals practicing compulsory trades will appear on the Skilled Trades Ontario Public Register, and renewals will only be required for Certificates of Qualification in compulsory trades. Skilled Trades Ontario will issue Certificates of Qualification in compulsory and non-compulsory trades with exams.
