Becoming an electrician is one of the most reliable career bets in the skilled trades — strong demand, good pay, and a licence that travels. If you’re in Niagara and considering it, here’s how the path works in Ontario in 2026: the two licences, the hours, the exam, and what it pays.
A quick note: requirements and wages change, and the trade’s curriculum is being updated. Confirm current details with Skilled Trades Ontario before relying on anything here.
Two licences: 309A and 442A
Ontario has two main electrician licences, and the difference matters:
- 309A — Construction & Maintenance Electrician. The broad one: works in residential, commercial, and industrial settings, installing new systems and troubleshooting, maintaining, and repairing existing ones. This is a compulsory Red Seal trade, meaning you must be a registered apprentice or licensed journeyperson to legally do the work in Ontario.
- 442A — Industrial Electrician. Works exclusively in the industrial sector, often on larger machinery, higher voltages, and control circuits including PLC systems. The 442A licence is not mandatory to do industrial electrical work, but employers expect proper training and competence.
For most people, the 309A is the licence that opens the most doors, since it covers the widest range of work.
The training: hours and time
Both the 309A and 442A apprenticeships require 9,000 hours total — about 8,160 hours of on-the-job work plus 840 hours of in-school training — typically taking around five years. The in-class portion is delivered in levels (the curriculum is being modernized, with a new Level 1 phased in from September 2024 and a new Level 4 for 309A/442A coming September 2026). A high school diploma isn’t strictly required, but it’s preferred, and math and physics genuinely matter — you’ll use them.
The path, step by step
- Build a foundation (optional). Many people start with a one-year college electrical certificate or a pre-apprenticeship to learn theory and safety before finding a sponsor.
- Find a sponsor. You need an employer approved to train apprentices.
- Register your Training Agreement with Skilled Trades Ontario.
- Complete your hours and levels — logging work and attending in-class training.
- Write the Certificate of Qualification exam (the 309A C of Q is also the Red Seal exam).
- Get certified — pass and you’re a licensed journeyperson, with the Red Seal allowing you to work across Canada.
What electricians earn
Electricians are among the better-paid trades. The Government of Canada’s Job Bank puts electrician wages in Ontario at roughly $20.00 to $50.50 an hour, with apprentices at the lower end and experienced journeypersons near the top. Industrial electricians run roughly $29.00 to $48.00 an hour in Ontario, and specialized high-voltage powerline work pays higher still. As always, certification and specialization drive pay more than years alone — treat these as ranges and verify the current figures on Job Bank.
Is it a good fit?
The trade suits people who like solving problems, working with their hands, and don’t mind heights or tight spaces. It’s a steady career with a clear earn-while-you-learn path and no university debt. Demand for electricians remains strong across Ontario, and the portability of the Red Seal means you can chase higher-paying work elsewhere later without starting over.
The bottom line
To become an electrician in Ontario, you complete a roughly 9,000-hour apprenticeship (about five years), pass the Certificate of Qualification exam, and — for the 309A — earn the Red Seal. The 309A is the compulsory, broad licence most people pursue; the 442A is the industrial specialist. Pay is strong and rises with certification and specialization. As with every trade, the hardest step is landing that first sponsor.
