Is this the same trade as a heavy equipment mechanic?

No. A truck and transport mechanic inspects, diagnoses and repairs commercial trucks, emergency vehicles, buses and other road transport vehicles, including some electric, hybrid and alternative-fuel vehicles. The work covers engines, brakes, steering, suspension, drivetrain, electrical systems, HVAC and hydraulics.

A heavy equipment mechanic works mainly on construction and off-road machinery. Those are separate trades, with different apprenticeship programs and exams. When you read a “heavy duty” posting outside Quebec, check whether the shop services highway trucks, off-road equipment, or both.
