How to become a firefighter in Ontario
Everything you need to get hired in 2026 — the requirements, certifications, the OFAI FACT test, salary expectations, and the exact steps that take you from applicant to firefighter.
Becoming a firefighter in Ontario is one of the most competitive career paths in the province — but it's also one of the most achievable if you understand the process. The path runs through clear requirements, recognized certifications, and a standardized testing process used by most departments. This guide walks you through each step, then shows you how to prepare for the part that filters out the most candidates: the written aptitude exam.
- Be 18+ with an Ontario high school diploma (OSSD)
- Valid driver's licence, clean abstract, and clean background check
- Current CPR-C and Standard First Aid certification
- NFPA 1001 Level I & II firefighter certification
- Pass the OFAI FACT (or CPS) written and physical testing
The 6 steps to becoming an Ontario firefighter
- 1
Meet the basic requirements
Be at least 18, hold an Ontario Secondary School Diploma (OSSD) or equivalent, have legal status to work in Canada, and be able to pass a medical and vision exam. Good colour vision and hearing are required by most services.
- 2
Get your driver's licence and clean abstract
Hold a valid Ontario driver's licence — many departments require a Class D or DZ (air brake) endorsement, or expect you to obtain it after hire. A clean driving abstract and clean criminal background check are mandatory.
- 3
Complete CPR-C and Standard First Aid
Current CPR Level C (Healthcare Provider) and Standard First Aid certification are required by nearly every Ontario fire service. Keep these certificates current throughout your application.
- 4
Earn NFPA 1001 Level I & II certification
This is the core firefighter certification. Most candidates complete a Pre-Service Firefighter Education and Training program at an Ontario college, or train through the Ontario Fire College / an accredited academy. NFPA 1072 (HazMat) and NFPA 1035 are valuable add-ons.
- 5
Pass the OFAI (or CPS) testing process
Register with Ontario Fire Administration Inc. (OFAI). You'll complete the FACT written aptitude exam, a CPAT-style physical fitness test, and a swim/medical stage. Some departments use the CPS written test instead. Your written score is often the first gatekeeper, so prepare thoroughly.
- 6
Apply to departments and ace the interviews
Watch for postings from Toronto, Ottawa, Mississauga, Hamilton, and smaller services. Submit a tailored application, then prepare for behavioural and panel interviews. Volunteering, community involvement, and a clear 'why firefighting' story make you stand out.
The test most Ontario applicants fail
The single biggest reason qualified candidates get cut early is the written aptitude exam. Most Ontario services use the OFAI FACT — a timed test covering memory, reading comprehension, mathematical reasoning, mechanical aptitude, and human relations. Other departments use the CPS written test. Both reward candidates who practice under realistic, timed conditions rather than cramming.
Firefighter Academy is built specifically for these exams. You get realistic questions across every section, full timed simulations, and analytics that show exactly where to improve. Dial in your mechanical aptitude and memory sections — the two that trip up the most applicants.
Firefighter salary in Ontario
Firefighting is a well-paid career in Ontario. New (fourth-class) firefighters typically start between $55,000 and $70,000, climbing to first-class pay of roughly $90,000 to $115,000 after about four years, plus pension and benefits. Larger services like Toronto, Ottawa, Mississauga, and Hamilton sit at the top of that range. The strong compensation is one reason the competition — and the importance of acing the written test — is so high.
