As an HVAC Engineer with the Department of National Defence, you will design, install, maintain, and repair heating, ventilation, and air conditioning systems in military facilities across Canada. You will apply your mechanical engineering expertise to ensure optimal climate control in diverse environments, from administrative buildings to specialized operational facilities. Your work directly supports the comfort, safety, and operational readiness of Canadian Armed Forces personnel and civilian staff.
Your responsibilities include conducting system assessments, developing technical specifications, troubleshooting equipment failures, and overseeing preventive maintenance programs. You will collaborate with facilities management teams, contractors, and other engineers to implement cost-effective solutions that meet federal building codes and environmental standards. You may also be involved in upgrading aging infrastructure and implementing energy-efficient technologies to reduce operational costs.
You will work in a structured, team-oriented environment within DND's Facilities and Infrastructure branch. Your role offers exposure to cutting-edge HVAC technology, large-scale projects, and the satisfaction of maintaining critical infrastructure that supports national defence operations. Work is typically performed during regular business hours, though emergency repairs may require on-call availability.
Key Responsibilities
Perform heating, ventilation, and air conditioning (hvac) tasks maintaining government facilities and assets, Operate tools, equipment, and machinery safely, Follow technical specifications and safety procedures, Maintain records of work performed and materials used
Post-secondary education or equivalent experience relevant to the position
Training
To enter this career, you typically need a diploma or degree in mechanical engineering, HVAC technology, or a related field from an accredited Canadian institution. Many successful candidates hold a Bachelor's degree in Mechanical Engineering with a focus on HVAC systems or building services. Some positions may accept equivalent work experience in lieu of formal credentials.
Professional certification as a Professional Engineer (P.Eng.) in your province is highly valued and may be required for senior positions. You should maintain current certifications in refrigerant handling (such as EPA or provincial equivalents) and knowledge of relevant codes including the National Building Code of Canada. DND supports ongoing professional development through tuition assistance programs, technical certifications, and participation in industry associations such as the Canadian Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).
Entry Plans
You can enter the DND civilian workforce as an HVAC Engineer through several pathways. The primary method is to apply for advertised competitions through the DND Civilian Careers Portal and the Public Service Commission (PSC) website. These competitions are open to Canadian citizens and permanent residents and typically require submission of a resume, cover letter, and supporting documentation demonstrating your qualifications.
You may also enter through the Federal Student Work Experience Program (FSWEP) if you are a full-time student, which can lead to indeterminate employment. Lateral moves from other federal departments or from the Canadian Armed Forces are another pathway if you already hold a position in the federal Public Service. Some opportunities may arise through staffing pools or priority hiring initiatives for veterans or Indigenous peoples. Networking with DND facilities management personnel and attending recruitment events can provide additional insights into upcoming opportunities.
Part-Time Options
Part-time opportunities in HVAC Engineering roles with DND are limited but may be available, particularly for project-based work or during facility expansions. Most HVAC Engineer positions are full-time permanent roles due to the ongoing nature of facilities maintenance and emergency response requirements.
Flexible work arrangements, including flexible hours and telework, are increasingly available within the federal Public Service. While some aspects of HVAC work require on-site presence (system inspections, maintenance, repairs), administrative tasks such as design work, report writing, and planning may be performed remotely. Employees should discuss flexible work options with their manager and their department's human resources office, as arrangements vary by operational needs and facility location. Emergency on-call requirements may apply depending on your specific position and assignment.
