Car Maintenance Checklist for Canadian Drivers

Monthly quick checks (10 minutes)

• Tire pressure, including the spare — check when tires are cold, before driving
• Tire tread depth — the legal minimum across Canada is 1.6 mm; replace well before you hit it
• All exterior lights: headlights, tail lights, brake lights, turn signals, reverse lights
• Windshield washer fluid level — top up with a winter-rated fluid once temperatures drop below freezing
• Wiper blades — replace at the first sign of streaking or skipping, not once they're unusable
• Dashboard warning lights — note anything new, even if it clears on its own
• Visible fluid leaks under the vehicle after it's been parked overnight

Mileage-based service

• Oil and filter change — follow your owner's manual or the vehicle's oil-life monitoring system; conventional oil is commonly 5,000–8,000 km, full synthetic often stretches to 10,000–16,000 km, but the manufacturer's guidance overrides any general rule
• Tire rotation — typically every 8,000–12,000 km, or every second oil change, to even out wear
• Cabin air filter — typically every 20,000–25,000 km, sooner if you notice reduced airflow or odour
• Engine air filter — typically every 30,000–50,000 km, sooner in dusty or gravel-road conditions
• Brake pad inspection — have thickness checked at every tire rotation; don't wait for the squeal
• Coolant/antifreeze — follow the manufacturer's interval, commonly every 5 years or 100,000–150,000 km for long-life coolant
• Transmission fluid — interval varies widely by vehicle; confirm in the owner's manual rather than assuming it's "lifetime"

Before winter

• Install winter tires once daily highs sit consistently under 7°C
• Have the battery load-tested — cold weather is when a marginal battery finally fails, and testing in October beats a dead battery in January
• Switch to winter-rated windshield washer fluid, rated well below your coldest expected temperature
• Check coolant concentration — it needs to be a genuine antifreeze mix, not mostly water, to protect against a hard freeze
• Check the block heater cord and outlet if your vehicle has one — a common no-start cause in extreme cold is a dead cord, not the engine
• Pack a winter emergency kit: blanket, shovel, sand or kitty litter for traction, warning triangle, flashlight, first aid kit, and a full tank of gas kept above half all season

Before summer / road trip season

• Have the AC system checked if airflow feels weak — refrigerant loss is gradual and easy to miss until it's hot out
• Check tire pressure again — pressure shifts with the seasonal temperature swing, not just from slow leaks
• Inspect wiper blades and washer fluid after a winter of salt and grit
• Check the battery terminals for corrosion buildup from winter road salt
• Reverse winter tires once nightly lows are consistently above freezing
• Top up or replace old windshield washer fluid with a summer bug-and-tar formula

Warning signs that mean see a mechanic now

• Squealing or grinding when braking — brake wear indicators are designed to squeal before the pads are metal-on-metal
• A new dashboard warning light that doesn't clear after a drive cycle
• Pulling to one side under braking or while driving straight
• A burning smell, especially after highway driving
• Any fluid leak that's new, growing, or a colour other than clear (water/condensation from AC is normal)
• A check engine light that's flashing rather than steady — that's an active-damage warning, not a "get to it eventually" one

Registration & insurance

• Confirm your registration renewal date and method — this is set provincially, not federally, so the process varies by where you live
• Renew insurance before the expiry date, and re-shop for a quote rather than auto-renewing every year
• Check whether your province requires an emissions or safety inspection for your specific situation — most of Canada doesn't require a routine annual inspection, but many provinces require one when a used vehicle changes ownership or after a collision
• Update your insurer if your annual mileage, commute, or primary driver changes — misreporting can affect a claim

Practical tips

• Keep a simple log — date, mileage, what was done — even a notes app entry. It's the fastest way to know what's actually due.
• A pre-trip check before any long drive (tires, fluids, lights) takes 5 minutes and catches most issues that would otherwise strand you.
• Deferred maintenance is rarely cheaper — a $40 cabin air filter ignored doesn't cost more later, but a skipped oil change or ignored brake wear usually does.
