Ontario Firefighter Practice Test Guide: FACT vs. CPS

If you're reading this, you're probably somewhere in the process of applying to a fire department in Ontario — and you've hit the wall that stops a lot of candidates before they ever get to a hose: the written test. Apply to fire departments in Ontario is a long, tedious, and expensive process. So here is all you need to know from someone who has been through it...

There are two main formats: FACT and CPS. Which one you write depends entirely on the department you're applying to. Getting clear on that distinction, then practicing accordingly, is the single most important thing you can do at this stage of your application.
This is your no-fluff breakdown of both tests, what's actually on them, and how to prepare like a serious candidate.

Before diving into each one, here's the lay of the land:

FACT (Firefighter Aptitude and Character Test) is generally administered by OFAI — Ontario Fire Administration Inc. It's the centralized test used by the majority of municipal fire departments in the province. Toronto, Brampton, Kitchener, St. Catharines, and over 100 other Ontario services accept an OFAI FACT certificate. You write it once, pass or fail, and the result is valid for 24 months across all participating municipalities. Some municipalities run their own testing (like Caledon, ON) but more of that later...

CPS (Cooperative Personnel Service Test) is administered through Fire Services Ontario (FSO) and is required if oyu're applying to Hamilton, Burlington, Niagara Falls, Windsor, and more. Municipalities like Mississauga, Richmond Hill, and others run their own recruitment processes and use the CPS format for their written screening.

In short: check the department's recruitment page. Don't assume.

The FACT consists of 110 multiple-choice questions and is weighted 45% aptitude measures and 55% character measures. It's a pass/fail exam — you won't get a score back, just a certificate or a rejection. Ofai
Here's the breakdown by section:

Reading Ability — 15 questions
Mathematical Reasoning — 15 questions
Map Reading — 10 questions
Writing Ability — 10 questions
Personal Characteristics — 60 questions

The Personal Characteristics section is the big one, and it's often the piece candidates underestimate. It measures interpersonal skills, teamwork, commitment, honesty, integrity, and emotional stability. At 60 questions and 55% of your overall weighting, this isn't filler — it's the bulk of the test.

What does that look like in practice? These are situational and behavioural questions. They're testing whether you have the character profile of someone who belongs in a firehouse. Think along the lines of:

There's no trick answer. The test is looking for patterns — someone with integrity who communicates through proper channels, doesn't go rogue, and doesn't look the other way. Answer consistently and honestly, because the questions are designed to catch contradictions.
The aptitude section (45%) covers the areas you'd expect: reading comprehension from a passage, basic math with some fire-related context, route interpretation from a map, and sentence structure.

Straightforward. This isn't calculus — it's practical numeracy under time pressure.
The FACT is a pass/fail exam with strict retake cooldowns. Fail your first attempt and you must wait 15 days to retake; fail again and the lockout extends to 30 days for every subsequent attempt.

That retake window matters. If you go in underprepared, you're not just wasting a sitting — you're adding weeks to your timeline in a competitive recruitment cycle. Prepare properly the first time.

A passing result unlocks access to apply to all participating OFAI municipal partners, and your certificate is valid for 24 months.

The CPS is a different animal, and most candidates who've only prepped for the FACT don't see it coming.
The CPS is a multiple-choice test consisting of 100 questions with a 2-hour time limit, divided into sections to gauge your understanding of written and oral information, arithmetic reasoning, maps, diagrams, and mechanical drawings. A passing score of 70 or higher is usually required. FireRecruitment
Here's what makes it genuinely harder: the oral/audio memory component.
At the start of the test, you listen to an audio passage — typically running about five minutes. You are not allowed to take notes while it plays. The passage will include specific details: names, badge numbers, addresses, distances, incident types, sequence of events. After it ends, you're expected to answer questions from memory.

This is a skill most people have never trained, and it shows. You might be sharp on math and reading comprehension but completely fumble the audio section because you've never practiced active retention under that kind of pressure. Five minutes of content. No notes. That's what you're working with.

Reading Comprehension — multi-paragraph passages with inference and detail questions
Mathematical Reasoning — percentages, unit conversion, ratios, problem-solving in a fire context
Mechanical Aptitude — pulleys, gears, levers, fluid dynamics, basic physics applied to tools and equipment

If you've never studied mechanical reasoning, that section will cost you marks. It's not intuitive for everyone, and it requires dedicated practice.

The general consensus among candidates who've written both: the CPS written is harder. It tests a broader and more demanding skill math and mechanical aptitude skills, and the memory component adds a layer of stress that the FACT simply doesn't have.

There's a lot of generic advice out there — "study math" and "read more." That's not a plan. Here's what works:

1. Know which test you're writing.
This sounds obvious but candidates mess this up. Check the department's website. If it's an OFAI-listed service, you're writing the FACT. If it's Mississauga, Richmond Hill, or another independently-recruiting municipality, confirm the format before you spend three weeks prepping the wrong test. This is important for services who do their own testing in-house.

2. Take timed practice tests, not just review questions.
Both the FACT and CPS are time-pressured. The cognitive experience of doing 110 questions against a clock is different from reviewing question banks at your own pace. Train the way you'll compete.

3. Practice the audio component specifically.
If you're writing the CPS, this is non-negotiable. Listen to news broadcasts, podcasts, or recorded incidents and practice recalling specific details afterward — numbers, names, sequence of events. Your brain needs reps at this before test day.

4. Don't tank the Personal Characteristics section by overthinking it.
On the FACT, the character section isn't something you can cram. Be consistent. Answer as someone with integrity, good judgment, and a team-first mindset — because that's who should be in a firehouse, and the test is built to identify exactly that.

5. Nail mechanical reasoning early.
This section rewards preparation. Gears, pulleys, levers, mechanical advantage, hydraulics — there's a finite set of concepts and they repeat. Spending a few hours on fundamentals before your first practice test will pay off disproportionately.

When I did the CPS test for the first time at Fire Services of Ontario, I completely underestimated how tired I would be. A full day of physical testing, including the CPAT, swim test, sit-up test, VO2Max treadmill test, etc. had me completely drained. It was impossible to think and concentrate. So that is why you need to be prepared - you will NOT come into testing day feeling good if you are not prepared. Everything is working against you. You need to prep like crazy so you don't fall flat on the written test at the end of the day.

The Ontario firefighter written test isn't something to wing. Both the FACT and the CPS are designed to identify candidates who are sharp, grounded, and built for the job — and both will expose gaps in candidates who didn't put in the work.

The good news: these tests are learnable (you were taught long division in grade school, so it's in your brain somewhere... we just need to brush up on it). The skills they assess respond to focused, deliberate practice. You don't need to be a math genius or have a photographic memory. You need to train the right material, under the right conditions, enough times that the actual test feels familiar.

Firefighter Academy is built specifically for Ontario candidates preparing for the FACT and CPS. Practice tests, timed simulations, and question banks mapped to the actual exam formats — so you walk in ready.
