Renting a Car in Canada: Licence, Insurance and Winter Tyres — What to Check Before You Go

For a tourist stay under six months, a valid foreign driving licence is legally enough to drive in every Canadian province: no International Driving Permit is required by law for a licence written in English or French, the country's two official languages. That's a notable difference from destinations like Japan or Chile, where an international permit is sometimes asked for at the counter.

In practice, it's worth nuancing this by province. In Quebec, a foreign licence alone passes without question, including with the police. In English-speaking provinces (Ontario, British Columbia, Alberta...), some independent rental companies or poorly briefed counter staff still ask for an International Driving Permit out of habit. Since it's free and takes a few minutes to obtain from your home country's authorities before departure, it's worth carrying one anyway to avoid any pointless argument after a long-haul flight.

The rest of the paperwork is standard: a credit card in the main driver's name is required for the deposit (a debit card is refused almost everywhere), and the minimum age is generally 21, with a young-driver surcharge common up to 24 or 25 depending on the company.

This is the point that catches most European travellers off guard, used as they are to "all-inclusive" rentals. In France or Spain, damage insurance (often called CDW) is usually bundled into the quoted rate, with a modest deductible. In Canada, it's the opposite: the base rate covers only the mandatory third-party liability, and protection against damage to the rental car — Collision Damage Waiver (CDW) or Loss Damage Waiver (LDW) depending on the company — is almost always a paid add-on, applied at the counter if it wasn't purchased online beforehand.

Without that add-on, the deductible you're liable for after an incident can run from CAD 500 to over CAD 3,000 depending on the vehicle category and the agency — an amount pre-authorised (blocked) on your credit card as soon as you pick up the car, whether or not an accident happens. Buying down that deductible at the counter typically costs CAD 20 to 45 per day, which adds up fast over a two- or three-week trip.

Before paying for that counter add-on, it's worth checking two cheaper alternatives: the car-rental cover often bundled with a premium credit card (Visa Premier, Gold Mastercard...), and independent rental car insurance bought online before departure, generally two to three times cheaper than the rental company's buy-down — provided you confirm it covers Canada and any unpaved roads on your route.

For a road trip planned between December and March, one rule changes everything: in Quebec, the law requires approved winter tyres on every vehicle registered in the province from December 1 to March 15, and this obligation explicitly applies to rental companies, who must supply a compliant vehicle. There is no grace period for the 2025-2026 season: offenders face a fine of CAD 200 to 300 for a first offence, doubling for a repeat offence within twelve months.

In practice, the major rental agencies based in Quebec automatically fit winter tyres from late November at no extra charge — but it's worth confirming explicitly at booking if your trip falls within these dates, especially with an independent rental company or for a pickup just before December 1. The rule differs from province to province, which can cause confusion for a route that crosses several regions of the country.

An itinerary combining the Canadian Rockies with US national parks (Glacier National Park, Seattle) is possible in a rental car, but never without notifying the rental company in advance. Most major agencies allow crossing into the US, sometimes for a supplement or a signed authorisation form before departure; without that step, crossing the border with the car is a breach of contract that can void any insurance cover for an incident on the US side.

On insurance itself, the good news is that cover purchased in Canada generally extends to the United States with no extra purchase — some rental companies hand over a yellow "non-resident insurance card" to keep in the vehicle as proof of insurance in case of a check. Also check mileage and drop-off terms: a one-way trip between the two countries almost always triggers an additional drop fee, which varies widely by distance and rental company.

Wildlife on the road isn't just a Canadian road-trip cliché. A study by Christian Dussault and co-authors, published in 2006 in the journal Wildlife Biology and based on thirteen years of data along a highway through the Laurentides Wildlife Reserve in Quebec, recorded 754 moose-vehicle collisions on that single stretch of road: the peak was not in winter but in the second half of June, with a high level maintained from mid-May to late August (scholar.google.com/scholar?q=Dussault+Poulin+Courtois+Ouellet+Temporal+spatial+distribution+moose-vehicle+accidents+Laurentides). A collision with an adult moose — an animal that can weigh over 500 kg — is markedly more dangerous than hitting a deer: the animal's centre of gravity tips its mass straight into the cabin on a head-on impact.

The basic precautions are simple and apply across the whole Canadian road network, not just Quebec: slow down as soon as you see the yellow crossing-zone signs, stay especially alert at dawn and dusk when visibility drops and animal activity rises, and never swerve sharply to avoid an animal — braking firmly in a straight line remains the safest move, since running off the road is statistically deadlier than the collision itself.
