As an HVAC Mechanic with the Department of National Defence, you will be responsible for installing, maintaining, and repairing heating, ventilation, and air conditioning systems across DND facilities and military bases. You will work with complex mechanical and electrical components, ensuring that climate control systems operate safely and efficiently in diverse environments ranging from administrative buildings to specialized military installations. Your work is critical to maintaining comfortable and functional work environments for Canadian Armed Forces members and civilian employees. You will diagnose system malfunctions, perform preventive maintenance, and execute repairs using specialized tools and technical knowledge. HVAC Mechanics work collaboratively with other trades professionals, facility managers, and engineering teams to ensure all systems meet safety codes and operational standards. This is a skilled trade position that requires both technical expertise and practical problem-solving abilities. You may be required to work irregular hours, including evenings and weekends, to address urgent heating, cooling, or ventilation issues that could impact operations or personnel safety.

Post-secondary education or equivalent experience relevant to the position
Training
To qualify as an HVAC Mechanic, you typically need a high school diploma or equivalent (Grade 12) and completion of a recognized HVAC apprenticeship program, which usually takes 4-5 years and combines classroom instruction with on-the-job training. Upon entering the Canadian Armed Forces or DND as a civilian, you may be required to obtain or maintain a provincial/territorial HVAC certification or journeyperson designation, depending on the province where you work. Many provinces require completion of a registered apprenticeship and passing a certification exam. DND provides specialized training in military-specific HVAC systems, equipment, and facility standards. Professional development opportunities include advanced certifications in refrigeration, building automation systems, energy efficiency, and supervisory or technical management roles. The department supports employees pursuing additional qualifications and may cover costs for upgrading certifications or attending technical courses that enhance operational capability.
Entry Plans
You can enter this career through several pathways. The primary method is through open competitions advertised on the Public Service Commission (PSC) website and DND career portals, where you must meet the qualification requirements and be successful in the selection process. If you are a Canadian Armed Forces member, you may transition to a civilian HVAC Mechanic position through internal mobility or release programs. DND also hires through staffing pools that may be established following competitive processes, allowing for faster placement when positions become available. If you have relevant trade experience from the private sector or other government departments, you may be eligible to apply as a lateral move. Some entry opportunities exist for apprentices or those with partial trade qualifications who can complete their training while employed with DND. Student work-study and co-op programs may also be available during your apprenticeship, providing early exposure to DND operations and potential pathways to permanent employment.
Part-Time Options
HVAC Mechanic positions with DND are primarily full-time roles due to the nature of facility maintenance and the requirement to respond to urgent system failures. However, part-time or casual opportunities may be available for specific projects, maintenance schedules, or seasonal work, depending on facility needs and staffing levels. Remote work is not applicable to this trade, as the role requires hands-on work in mechanical rooms, on rooftops, and throughout building systems. Flexible scheduling may be possible in some circumstances, though shift work, on-call duties, and emergency response requirements are common in this position. If you are interested in part-time or flexible arrangements, discuss options with DND Human Resources or the hiring manager, as availability depends on the specific location and operational requirements. The Canadian Armed Forces and DND are committed to supporting work-life balance where operationally feasible.
