Marine Service Shop Department

OEM Cert Support

Grand Harbour Marina is a premier waterfront destination located in Lagoon City, Brechin, Ontario — on the beautiful east shore of Lake Simcoe. Under new ownership and management, we are transforming this iconic marina into a destination defined by elevated service, world-class amenities, and a commitment to excellence across every department.

Our Marine Service Shop is the technical heartbeat of the marina — the place where our members and guests trust us with their most valued investments. We are building a marine service team grounded in technical skill, professional pride, and a genuine commitment to getting it right. If you are an apprentice marine mechanic who is serious about your trade and wants to grow your career in a supportive, well-equipped Ship Yard environment — we want to hear from you.

As Marine Mechanic Apprentice at Grand Harbour Marina, you will work alongside our Chief Marine Engineer in the Marine Service Shop, developing your skills across the full scope of marine engine service, diagnostics, and repair on a diverse fleet of inboard, outboard, and stern drive engines. You will assist with routine service and maintenance, progress to more complex diagnostics and repair work as your skills develop, and receive active support for OEM certification training with Mercury, Volvo Penta, and Yamaha.

This is a full-time position with a benefits package, a structured path for skill development and certification, and the opportunity to grow into a fully qualified marine technician as the marina’s service department expands. Mercury Marine and Volvo Penta certification are strong assets for the full-time role. Yamaha certification is also highly valued and is particularly relevant during the seasonal peak period.

We are looking for someone who is eager to learn, takes their trade seriously, and brings the right attitude to the Marine Service Shop every single day.
