How to become an electrician in Ontario
For a new 309A apprentice, the route runs from finding a sponsor and registering your training to completing workplace and classroom requirements, then the certifying exam. Start by checking your eligibility with Skilled Trades Ontario and organizing your sponsor search.
Use our sponsor search plan to organize employers, training organizations and contacts. Ask each organization whether it is accepting applicants who have not yet registered as apprentices, and which electrical trade it trains.
- Keep a short list of contractors and training organizations you can realistically travel to.
- Read the application instructions before sending a resume. Note the deadline and any requested school records.
- Ask who would sponsor your training and how supervision, school periods and work locations are arranged.
- Record the date you contacted each organization and its stated follow-up process.
These are search steps, not a list of employers currently hiring. For the registration route, start with the Ontario apprenticeship guide.
Looking for an electrician apprenticeship in Toronto?
Search for both “electrician apprentice” and “309A apprentice,” then compare results within a commute you can sustain. A company’s office address may differ from its job sites. Before applying, ask where work starts, how often locations change and whether transportation is needed.
Search Job Bank using Toronto or your nearby municipality. Use Employment Ontario for job-search support and referrals. Check an organization’s own application page before sharing documents.
Check the school and workplace training details
309A apprenticeship combines workplace and classroom training. Skilled Trades Ontario’s trade page flags a phased electrical curriculum change, with new levels 3 and 4 implemented from September 2026. Before relying on a course schedule or older program summary, ask the training provider which curriculum and school hours apply to your cohort.
Questions to take to a sponsor or school
- Is this the 309A apprenticeship route, a preparation course or a different electrical trade?
- Do I need a registered training agreement before applying for this school intake?
- What documents and education requirements apply to me?
- Which curriculum, classroom schedule and work hours should I plan for?
- What costs should I budget for, and who provides tools and safety equipment?
309A is a compulsory trade in Ontario and participates in the Red Seal Program. Confirm your registration and certification route with Skilled Trades Ontario before beginning regulated work.
Need experience before applying?
A preparation program may help you explore the work and build skills. Compare the Ontario pre-apprenticeship route with applying directly to a sponsor. A course advertised as “electrical” should not be assumed to register you as a 309A apprentice.
