Construction and Maintenance Electricians
Construction and Maintenance Electricians work on virtually every kind of residential, industrial and commercial building. They lay out, assemble, repair, maintain, connect and test electrical fixtures, apparatus, control equipment and wiring. They also work on alarm, communication, light, heating and power systems. Construction and Maintenance Electricians also construct and maintain generation, transmission and distribution stations.
Construction and Maintenance Electricians’ work is physically demanding and they are often outside in the elements. They must be able to distinguish colours.
The apprenticeship for a Construction and Maintenance Electrician is made up of five 1,800 hour terms. Each term is approximately one year in length. The apprenticeship includes three in-school training sessions of eight to 10 weeks each at a community college.

Mechanical Maintainer
Mechanical Maintainers play an essential role in the equipment surveillance and maintenance program to ensure safe and reliable plant operation. For new facilities, Mechanical Maintainers commission plant equipment and systems. They also provide feedback to technical staff regarding the condition of the equipment through dismantling, inspection and reassembly. They carry out predictive maintenance, preventive, corrective and breakdown maintenance to ensure reliable system operation and ensure the equipment is in a good state of repair.

Control Technician

Control Technicians spend a large portion of their day inspecting, maintaining and repairing instrumentation, electronics or electrical equipment. They also perform diagnostic and maintenance routines. Control Technicians may also be asked to train new team members, so they need to be comfortable communicating and working confidently and safely with others. Some days will require several hours of paperwork, which is repetitive but essential to the success and safety of everyone. Control Technicians must be willing to work eight, ten or twelve-hour shift work and they’ll need to be comfortable being on duty at any hour of the day.
