What an automotive service technician does
Automotive service technicians inspect, diagnose, maintain and repair cars and light trucks. On a typical day that means scan-tool diagnostics, brake and suspension work, engine and driveline repairs, electrical troubleshooting and scheduled maintenance, followed by clear notes on the repair order. In a dealership they also complete warranty and recall work to manufacturer standards. The quality of their diagnosis decides whether a customer’s car is fixed the first time or comes back.
Automotive service technician is a compulsory trade in Ontario, so only certified technicians and registered apprentices can legally do the work. That shrinks the pool, and the best technicians tend to stay where they are busy and well equipped. Finch approaches working technicians directly, confirms certificates on the Skilled Trades Ontario public register and matches brand, diagnostic and hybrid or electric vehicle experience to your shop, so you interview people ready for real work.
