Air Conditioning Systems Draftspersons prepare technical drawings and documentation for the design, installation, and maintenance of air conditioning systems in Department of National Defence facilities across Canada. Working as part of multidisciplinary teams, you will translate engineering concepts into detailed plans that contractors and technicians use to construct and service HVAC systems in military buildings, hangars, and infrastructure. Your drawings ensure that air conditioning systems meet building codes, safety standards, and operational requirements specific to defence facilities.
Your day-to-day responsibilities include creating detailed technical drawings using computer-aided design (CAD) software, reviewing blueprints and specifications with engineers and contractors, calculating system layouts and ductwork dimensions, and ensuring all documentation complies with National Building Code requirements. You will work in design offices, attend site meetings, and coordinate with facilities management teams to ensure accurate installation. This role requires strong attention to detail, as errors in drawings can result in costly delays or system failures in critical defence infrastructure.
You will work in a professional office environment during regular business hours, though occasional site visits to DND facilities may be required. The work combines technical drawing skills with practical knowledge of HVAC principles, making this an ideal role for someone who enjoys both design work and hands-on problem-solving.
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 qualify for this position, you typically need a high school diploma or equivalent and completion of a two-year technical diploma or certificate in HVAC technician training, drafting technology, or a related field from a recognized Canadian institution. Some candidates enter with one year of relevant post-secondary education combined with documented technical work experience.
Proficiency in industry-standard CAD software such as AutoCAD, Revit MEP, or similar programs is essential. Knowledge of HVAC systems, ductwork design, load calculations, and familiarity with the National Building Code of Canada are required. Many successful candidates hold or are working toward certification as a Drafting Technician through Professional Engineers Ontario (PEO) or equivalent provincial bodies.
Ongoing professional development is supported through training in advanced CAD applications, building information modelling (BIM), energy-efficient system design, and emerging HVAC technologies. DND encourages participation in industry associations such as the Canadian Sheet Metal Workers' Association or ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) to maintain current knowledge and professional networks.
Entry Plans
Entry into this career within the Department of National Defence typically occurs through external public service competitions advertised on the Government of Canada Jobs website (jobs.gc.ca). Positions are classified at the Technician level, with salary ranges determined by Treasury Board pay scales.
The Public Service Commission regularly conducts recruitment campaigns for HVAC and facilities support trades. Candidates apply competitively and participate in assessments that evaluate technical knowledge, CAD proficiency, and mechanical aptitude. Previous experience in HVAC design, drafting, or related trades strengthens applications.
Lateral moves are possible if you currently work in other Government of Canada departments or agencies in related technical roles. DND may also accept candidates through internal staffing processes if suitable positions become available. Some opportunities exist for students through the Federal Student Work Experience Program (FSWEP) or the Post-Secondary Recruitment Campaign (PSRC), which can lead to permanent employment upon graduation. Eligibility requires Canadian citizenship or permanent resident status and the ability to obtain a valid security clearance.
Part-Time Options
Air Conditioning Systems Draftsperson positions within DND are primarily full-time, permanent positions working standard office hours (typically 37.5 hours per week). However, flexible work arrangements may be available on a case-by-case basis depending on operational requirements and manager approval.
Remote work options have expanded within the federal public service and may be available for certain drafting tasks that do not require on-site facility assessments or face-to-face coordination meetings. The nature of this work—which often involves site visits and real-time collaboration with construction teams and engineers—typically requires a regular office presence, though hybrid arrangements may be negotiated.
Job-sharing and part-time opportunities are uncommon in this classification but may occasionally arise. Interested candidates should discuss flexible work options during the recruitment process or after appointment. All part-time and flexible arrangements must be approved by management and aligned with operational needs and collective agreement provisions for your employment group.
