Skilled Trades Ontario (STO) and Compulsory Trade Status
In Ontario, the Electrician – Construction and Maintenance (309A) and Domestic and Rural (309C) trades are compulsory, meaning individuals must be registered apprentices or licensed journeypersons to work legally in the trade. Apprenticeship programs are administered by Skilled Trades Ontario (STO), the provincial authority responsible for regulating and promoting the skilled trades, ensuring standardized training and certification pathways.
Structured Training Hours and “Red Seal” Endorsement
Electrician apprenticeships in Ontario typically require approximately 9,000 hours of combined on-the-job training (around 8,160 hours) and in-school technical instruction (around 840 hours), usually taking about five years to complete. Upon successful completion of the apprenticeship and passing the Certificate of Qualification (C of Q) exam, electricians also receive a “Red Seal” endorsement, which signifies a national standard of excellence and allows them to work in other Canadian provinces without further examination.
