The firefighter aptitude test is not a firefighting knowledge test. It is a cognitive aptitude assessment. No prior firefighting experience is required or tested.
Once you know which department you are targeting, the written exam is the part you can start preparing for immediately - long before a recruitment window opens.
Across the major Canadian tests, the abilities measured are consistent: reading comprehension, mathematical reasoning, mechanical aptitude, spatial and map reading, and a situational judgment or character component. What the publishers are really probing is whether you can absorb written procedures and reason under time pressure, and whether your judgment and reliability fit a crew. The format and emphasis differ from test to test - which is why preparation has to be test-specific.
The two tests that dominate Canadian hiring differ most meaningfully in what a passing result actually means:
FACT/OFAI is used across central Ontario by Toronto, Brampton, and 100+ other departments. It covers reading ability, mathematical reasoning, map reading, writing ability, and personal characteristics across 110 multiple-choice questions. Critically, it is pass/fail - no score is reported. Retake cooldowns are 15 days after a first failure and 30 days for each subsequent attempt. A pass certificate is valid for 24 months and costs $75.
CPS is administered through Firefighter Services Ontario for southwestern Ontario departments and is used by fire departments across other Canadian provinces and the US. It covers reading comprehension, oral comprehension, arithmetic reasoning, maps and diagrams, mechanical reasoning, and situational judgment across 100 questions in two hours. Unlike FACT, it is a scored test - a passing score of 70 is typically required, but candidates aiming to rank competitively should target significantly higher.
Match your preparation to your department's exam:
Both the FACT and CPS are timed - and at competitive departments like Toronto and Calgary, passing the minimum threshold is rarely enough to advance. Ranking high enough to get hired is a different standard.
