Do you enjoy solving mechanical problems under pressure, working with powerful machinery, and seeing Ontario from the water? If you’re drawn to the Great Lakes and St. Lawrence Seaway, becoming a Marine Engineer (Ship) could be a strong career path for you.

Job Description

Marine Engineers (ship) are the technical leaders who keep a vessel’s propulsion, power generation, and onboard systems running safely and efficiently. In Ontario, you’ll find opportunities on Great Lakes bulk carriers, tankers, tug-and-barge units, research vessels, and provincial ferries. You will work as part of the engine department, typically progressing through ranks from Fourth-Class Engineer up to Chief Engineer under Transport Canada’s certification system.

You operate and maintain diesel engines, Boilers (where applicable), generators, pumps, fuel systems, Electrical distribution, heating/Ventilation/air conditioning (HVAC), Automation, and pollution-Prevention systems. You also ensure Compliance with Canadian laws and international standards (STCW, ISM Code, MARPOL), and you coordinate repairs with shipyards and vendors during port calls or winter lay-up.

Daily work activities

  • Standing engine-room watch or working day shift, often on a rotation such as 4 hours on/8 hours off, or daywork during Maintenance periods.
  • Monitoring and adjusting machinery parameters: fuel consumption, lube oil pressures, cooling temperatures, electrical loads.
  • Planned maintenance: overhauling pumps and valves, changing filters, aligning shafts, servicing purifiers and separators.
  • Troubleshooting alarms and faults on automation and control systems (PLCs, sensors, actuators).
  • Recording logs and complying with the Safety Management System (SMS): permits to work, lockout/tagout, hot work, and confined space entries.
  • Fuel and lube oil management, bunkering Supervision, and environmental protection protocols.
  • Coordinating with the bridge team during manoeuvres, lock transits, and heavy weather.
  • Training and supporting junior engineers, engine-room ratings, and cadets.

Main tasks

  • Operate and maintain propulsion and auxiliary machinery.
  • Conduct scheduled preventive maintenance using a Computerized Maintenance Management System (CMMS).
  • Diagnose failures and perform corrective repairs.
  • Maintain safety, environmental, and quality documentation (ISM Code, MARPOL, class/flag records).
  • Lead or Support dry-dock and winter lay-up projects.
  • Manage spares, inventories, and technical purchasing requests.
  • Implement energy efficiency and fuel-saving measures.
  • Participate in emergency response: fire, flooding, blackout, and abandon ship drills.

Required Education

In Ontario, you can reach this career through Transport Canada’s certification pathway supported by college-level marine engineering programs. There are several entry points, from small-vessel certification to full officer licensing for large ships.

Diplomas and credentials

  • Certificate (short courses and entry certificates)
    • STCW Basic Safety/Marine Emergency Duties (MED) courses required for sea service.
    • Marine Medical Certificate from a Transport Canada–approved physician.
    • Small Vessel Machinery Operator (SVMO) certificate for small vessels and some ferries.
  • College Diploma/Advanced Diploma
    • Marine Engineering Technician (2 years) and Marine Engineering Technology – Marine Engineering Management (3 years) programs prepare you for Transport Canada officer exams and structured sea time.
  • Bachelor’s Degree
    • A Bachelor’s in Mechanical Engineering (Ontario) builds strong theory; to sail as an officer you still need Transport Canada sea service and exams. This pathway can help you progress to senior engineering roles ashore (technical superintendent, shipyard project engineer) or toward Chief Engineer with the proper sea service and certificates.
