Professional Mobile Diesel Mechanic Services in the Steeles Industrial Corridor

Stretching across the top of Scarborough, Steeles Avenue East is one of the busiest trucking corridors in the GTA — connecting Markham, Scarborough, and North York through dense industrial and logistics zones. Between warehouses, delivery hubs, and factory yards, trucks here are constantly on the move — and when one breaks down, it can jam the entire supply chain.

Our certified mobile diesel mechanics provide on-site diagnostics, repairs, and maintenance 24 hours a day, right along the Steeles corridor. We service all makes and models of heavy-duty trucks, trailers, and diesel engines — from Warden Ave to Markham Rd — without the need for towing or downtime.

Based in Toronto, we cover every kilometer of the city’s trucking routes. Whether you’re stuck at the 401–Dixie truck-stop stretch known as “Malfunction Junction,” in the Airport Road / Pearson logistics area, or along the 403/401 interchange corridor on the QEW through south Mississauga — our mobile mechanics arrive fast and get you rolling again.
