About the Ontario 309A Exam
The Ontario Construction and Maintenance Electrician 309A exam is a mandatory licensing requirement for electricians seeking certification through Skilled Trades Ontario.

With this license, you can pursue steady employment as a journeyperson electrician, advance into foreman or supervisor roles, and even transition into estimator, project manager, or contractor positions.
In Ontario, the 309A certificate is also the required first step toward becoming a Master Electrician, which allows you to run your own contracting business.

The explanations were simple and precise. No unnecessary jargon or filler, just solid content that gets to the point. The flow was natural, making it easy to follow. I wish I had started with this resource earlier. Highly efficient and reliable.
This prep guide gave me confidence I didn’t have before. The structure keeps you on track, and the explanations are detailed without being overwhelming. I appreciated how each section built toward the next. A very empowering resource.
Very thorough but never overwhelming. It explains not just the “what,” but the “why.” That made a big difference in how I understood the subject. The pacing is comfortable, and the writing is engaging. Highly effective.
