Electrician - Construction & Maintenance (309A)

An electrician plans, assembles, connects, installs, repairs, inspects, tests, verifies, and maintains electrical systems in various settings. Examples include residential, commercial, institutional and industrial. Electricians play a key role in protecting our environment by installing and maintaining green technology in new construction, retrofits, and commercial and industrial applications.

Lambton College offers the in-school portion of the curriculum set out by Skilled Trades Ontario.
