This training provides the basic core skills and knowledge common to all trades in the CAF. One of the goals of this course is to ensure that all recruits maintain the Forces physical fitness standard; as a result, the training is physically demanding.

Learn more about Basic Training here.

MSETs attend Naval Fleet School Pacific in Esquimalt, British Columbia or Naval Fleet School Atlantic in Halifax, Nova Scotia. Training takes three months and includes:

  • Basic mechanical, electrical and hull systems theory
  • Basic preventive and corrective maintenance for marine systems
  • The conduct of propulsion and ancillary engineering rounds
  • Equipment flash-up and shut-down procedures
  • Basic emergency responses to equipment failures
  • Repair of watertight and non-watertight closures

Following this initial in class training, MSETs will be posted to a ship to complete a hands-on training package and begin implementing the training they've received in real life scenarios.

MSETs may be offered the opportunity to develop specialized skills through formal courses and/or on-the-job training, including:

  • Integrated Platform Management Systems (IPMS)
  • Marine high voltage
  • Instrumentation and controls

Part time options

This occupation is available for part-time employment with the Naval Reserve at certain locations across Canada, including 24 Naval Reserve Divisions (NRDs). Reserve Force members may serve while going to school or working at a civilian job. They usually serve part- time at a Naval Reserve Division in their community and full-time for short periods of training or deployment on bases, ships and military operations within Canada or abroad.  They may also volunteer for long-term full-time contracts for up to several years. They are generally not posted or required to do a military move however, they are entitled to a military move for long-term full-time contracts. They can voluntarily transfer from one Naval Reserve Division to another as their civilian life relocates them.

MSET – Reserve serve as members of the Royal Canadian Navy. Like their Regular Force counterparts, they are employed for the operation and maintenance of all mechanical and structural systems onboard RCN ships up to the rank of Sailor 1st Class. Reserves provide technical expertise in support of boatsheds, performing advanced preventive and corrective maintenance on small boats. In support of Annual Naval Summer Training Unit (ANSU) conduct setup, operation and maintenance of power generation, ventilation, and related systems for portable operation centers and camps. In support of operations, Reserves may progress to taking charge of the maintenance teams and the equipment under their responsibility. Part-time employment is normally in the MSET’s NRD; some part-time training is conducted on weekends at naval schools or on ships afloat. Casual full-time employment on ships, ANSU exercises and operations, and at naval schools is commonly available in the summer months.

Find a Recruiting Centre

Reserve Force members are trained to the same level as their Regular Force counterparts for work that is common to the two components. Reservists usually begin training in their Naval Reserve Division to prepare them for the Basic Military Naval Qualification course at Naval Fleet School Quebec. Following basic training and naval environmental training, MSET - Reserve complete their occupation qualification at either Naval Fleet School Pacific in Esquimalt, British Columbia or Naval Fleet School Atlantic in Halifax, Nova Scotia for approximately nine weeks.

Reserve Force members usually serve part-time within their home unit for scheduled evenings and occasional weekends. They are paid 93% of Regular Force rates of pay, receive a reasonable benefits package including a pension plan, and may qualify for reimbursement of civilian education expenses.
