Yes, US car insurance does work in Canada for short visits. Your American auto policy follows you across the border for trips of up to six months, covering liability, collision, and comprehensive the same way it does at home. The reason is a long-standing agreement between US insurers and Canadian regulators, and the main things you need to prepare for are a special proof-of-insurance card and the fact that Canadian provinces require higher liability limits than most US states.
Why Your Policy Follows You Across the Border
The mechanism is called the Power of Attorney and Undertaking, or PAU. US insurance companies file this document with the Canadian Council of Insurance Regulators, and in signing it they agree to meet each province’s minimum insurance requirements whenever one of their policyholders has an accident in Canada. The arrangement has been in place since 1964, and nearly every major US insurer participates.1Canadian Council of Insurance Regulators. Private Passenger Automobiles
In practice, your insurer treats Canadian roads as part of your normal policy territory. The underlying assumption is that your vehicle will eventually return to its home base in the United States. If you’re moving to Canada or taking a job there, the PAU won’t help you, and you’ll need to buy a Canadian policy instead.
The Yellow Card You Should Carry
Before you leave, ask your insurer or agent for a Canadian Non-Resident Inter-Provincial Motor Vehicle Liability Insurance Card. Most people just call it the yellow card. It proves your American insurer has signed the PAU and that your policy meets Canadian standards, and it’s what you hand to a Canadian police officer or another driver after a collision.1Canadian Council of Insurance Regulators. Private Passenger Automobiles
You’ll need to give your insurer your vehicle identification number and policy details. Request the card at least two weeks before you leave to allow for processing and mailing. Your standard US insurance ID card is sometimes accepted, but not reliably, and driving without valid proof of insurance in Canada carries serious penalties. Fines run from a few hundred dollars in some provinces to C$25,000 or more in Ontario and Manitoba for a first offense, and several provinces authorize police to seize and impound an uninsured vehicle on the spot.2Société de l’assurance automobile du Québec.

Canadian Liability Minimums and the Automatic Step-Up
Canadian provinces require more third-party liability coverage than most US states. The baseline in most jurisdictions is C$200,000 for bodily injury and property damage you cause to others.1Canadian Council of Insurance Regulators. Private Passenger Automobiles A couple of provinces set the bar higher:
- Nova Scotia requires C$500,000 in minimum third-party liability.
- Manitoba’s government-run Autopac program goes up to C$500,000.
- Ontario, Alberta, New Brunswick, and most other provinces hold the line at C$200,000.
If your US policy carries lower limits than the province requires, the PAU forces your insurer to automatically meet the local minimum. You don’t have to do anything to trigger this step-up. Cause an accident in Nova Scotia with a $100,000 US liability limit, and your insurer must still honor at least C$500,000 in third-party liability.
The automatic step-up only brings you to the legal floor, though. Canadian injury claims can run well above provincial minimums, so if your domestic limits are modest, it’s worth asking your insurer about raising them before you go.
Quebec Works Differently
Quebec runs a public no-fault plan through the Société de l’assurance automobile du Québec that covers bodily injury regardless of who caused the crash. If you’re hurt in a Quebec traffic accident, the public plan pays your injury benefits.3Société de l’assurance automobile du Québec. If You Have an Accident in Quebec
The trade-off matters. You can’t sue another driver in Quebec for bodily injury damages like pain and suffering or lost wages, the way you often could in a US state or another Canadian province. For visiting American drivers in a non-Quebec-registered vehicle, benefits are also reduced in proportion to your share of fault. If you were 30% responsible, you receive 70% of the available benefits.3Société de l’assurance automobile du Québec. If You Have an Accident in Quebec
Property damage and liability for damage to other vehicles are still handled through your US policy. Only the bodily injury piece shifts to the public plan.
How Long the Coverage Lasts
Your US policy generally covers you in Canada for as long as you hold tourist status, which permits stays of up to six months. For a weekend trip or a two-week drive, you don’t need anything beyond the yellow card.
Once you cross that six-month line, or if you’re relocating, your American policy stops following you. You’ll need to buy insurance from a Canadian provider. In British Columbia, Manitoba, and Saskatchewan, basic coverage has to come from the provincial government insurer. In other provinces you shop among private carriers. Start the process early; a gap in valid coverage exposes you to the same heavy fines and impoundment risk as any other uninsured driver.
Rental Cars Are a Separate Question
If you’re flying in and renting rather than driving your own car across the border, the yellow card doesn’t apply. The rental agency carries its own provincial insurance on the vehicle, so you meet the minimum legal requirements through them.
Your US auto policy may still extend to the rental for collision and liability the way it does for a domestic rental, but not every policy does so across international borders. Call your insurer before the trip to confirm. Credit cards used to pay for the rental often add secondary coverage for damage to the vehicle, meaning they pay after your primary insurance. Anything beyond those layers, such as higher liability limits or loss-of-use protection, has to come from your personal policy, your card benefit, or the supplemental coverage sold at the rental counter.
If You Have an Accident
The first steps are the same as at home. Check for injuries, move to safety if you can, and call 911 if anyone is hurt. In most provinces you’re required to report the collision to police if the damage looks like it exceeds C$2,000. Ontario requires reporting all collisions to a Collision Reporting Centre within 24 hours regardless of the damage estimate.
Collect the other driver’s name, license number, vehicle registration, and insurance information. Photograph the damage, the scene, and any road conditions that mattered. Note the investigating officer’s name and badge number if police respond.
Call your US insurer as soon as you reasonably can. The Insurance Bureau of Canada recommends reporting any collision to your insurer within 48 to 72 hours.4Insurance Bureau of Canada. How to File an Auto Insurance Claim Most major American carriers run international claims desks reachable by toll-free number or through their apps, and your adjuster will coordinate with Canadian repair shops, towing, and vehicle recovery. If you’re a AAA member, your roadside assistance works throughout Canada through a reciprocal arrangement with the Canadian Automobile Association.5CAA Maritimes. Roadside Assistance
If the accident happens in British Columbia, Manitoba, Saskatchewan, or Quebec, the provincial government insurer may handle part of the claim directly, often the other driver’s side. Let your US insurer coordinate with the provincial authority rather than trying to navigate the local system yourself.
