Heavy Equipment Mechanics are skilled trade professionals who maintain, repair, and service large mechanical equipment used across Department of National Defence operations and facilities. This includes tanks, armoured vehicles, construction equipment, generators, and other heavy machinery critical to defence operations. As a Heavy Equipment Mechanic, you will diagnose mechanical problems, perform preventive maintenance, replace worn components, and ensure equipment meets safety and operational standards.
Your day-to-day work involves using specialized diagnostic tools, hand tools, and power equipment to troubleshoot and repair complex mechanical systems. You may work on hydraulic systems, engines, transmissions, brake systems, and other critical components. You will also maintain detailed maintenance records, follow safety protocols, and collaborate with other trades professionals and military personnel to keep equipment operational and mission-ready.
You will work in maintenance facilities, workshops, and field environments across Canada and potentially on international operations. This role requires physical strength, mechanical aptitude, attention to detail, and a commitment to safety. Heavy Equipment Mechanics are essential to operational readiness and play a vital role in supporting DND's defence and security mandate.

Training
To enter this career, you typically need a high school diploma or equivalent. Many Heavy Equipment Mechanics complete a formal apprenticeship program (typically 4 years) through provincial trade certification or equivalent military technical training. Some candidates may have prior experience in general mechanics or automotive repair.
Once hired, DND provides comprehensive on-the-job training specific to military equipment and defence systems. You may pursue professional certifications such as a Heavy-Duty Equipment Mechanic ticket (Red Seal certification), which is recognized across Canada and enhances career mobility. Ongoing professional development includes specialized equipment training, advanced diagnostic certifications, and leadership courses for those pursuing supervisory roles. DND supports continued learning through tuition assistance programs and access to technical training institutions.
Entry Plans
Entry into the Heavy Equipment Mechanic career typically occurs through Government of Canada public service competitions advertised on the Public Service Commission (PSC) website and the DND Careers portal. Competitions may be ongoing or periodic depending on operational needs and staffing levels.
You may enter as an apprentice (if you have not yet completed your trade certification) or as a certified mechanic if you hold valid Red Seal or equivalent credentials. Previous military service members may apply through casual or term positions before competing for permanent roles. Some candidates enter through student summer employment or youth programs such as the Canadian Armed Forces Reserve. Lateral moves from other mechanical trades within the Public Service are also possible. DND may establish recruitment pools to fill multiple positions across different locations, offering flexibility in placement options.
Part-Time Options
Heavy Equipment Mechanic positions are typically full-time, permanent positions given the operational demands and equipment maintenance schedules required by DND. However, casual or term employment options may provide part-time opportunities on a limited basis, depending on operational requirements and facility needs.
Flexible work arrangements such as compressed work weeks or shift scheduling may be available in some facilities to support maintenance operations across extended hours. Remote work is generally not applicable to this trade as the role requires hands-on work in workshops and field environments. Employees are entitled to standard federal leave benefits including vacation, sick leave, and family-related leave. Those seeking part-time work should inquire during the recruitment process about available contract types and scheduling options at their specific work location.
