“These guys truly know their stuff. I brought our entire fleet here for safety certifications and regular maintenance, and they handled everything efficiently and professionally. An accredited Ontario Safety testing facility with all-around great people. They've become our go-to shop for all fleet services.”
Mike M.

“So glad to have found a skilled heavy-duty mechanic right here in Newmarket. They handle our annual service as well as regular maintenance and unplanned repairs. They've worked on our Isuzu NQR Diesel, which has been a challenging vehicle — but they've consistently made light work of every problem.”
