About

A marine certificate of competency shows that you have the training, sea experience and skills to do a specific job on board a ship. Transport Canada issues these certificates for the whole country. The law requires them for officers on Canadian commercial vessels.

There are separate certificates for the deck side and the engine side. Deck officers earn Watchkeeping Mate and Master certificates. Engineers earn certificates that cover the care of engines, power systems and other machinery. The level you hold sets the size of vessel and the kind of voyage you may work on. People often start at a lower level and move up as they gain sea time.

These certificates open the door to many marine careers. They are used by ship captains, merchant marine officers, marine engineers, chief engineers and harbour pilots. Because the certificate is national, it applies on Canadian waters from coast to coast.

How to get it

  1. Choose deck or engine
    Decide whether you want to work as a deck officer or as an engineer. Your choice sets the training path and the certificate you will aim for.
  2. Complete approved marine training
    Enrol in a marine training program that meets Transport Canada standards. Many people attend a marine institute or college. Courses cover navigation or marine engineering, safety and ship operations.
  3. Complete basic safety courses
    Take the safety and survival courses that officers must hold. These usually include first aid, firefighting and sea survival.
  4. Gain sea service
    Work on board a vessel to build the practical experience required. Sea time is recorded and must be approved for the level of certificate you want.
  5. Pass the exams and assessments
    Sit the written exams and complete the practical assessments for your certificate. These check that you can handle the duties of the position safely.
  6. Apply to Transport Canada
    Send your application with proof of training, sea service and medical fitness. Transport Canada reviews it and issues the certificate if you meet the requirements.

The exam

Candidates sit written exams set by Transport Canada, and some levels also need practical or oral assessments. The exams test subjects such as navigation, ship stability, engineering knowledge, safety and the rules of the sea. You can prepare with a marine training program and by studying your own sea experience.

Keeping it
