The local Ministry of Advanced Education and Skills Development’s Employment Ontario apprenticeship office is currently responsible for signing and registering an Apprenticeship Training Agreement between a new apprentice and an employer for most apprenticeshipable trades in Ontario.


You must also be a member of the Ontario College of Trades’ Apprentices Class to work as an apprentice in an Ontario apprenticeship program that is established by the College of Trades.


The Technical Standards & Safety Authority regulates some trades in Ontario as well.
