Renting a car in Canada can come with a confusing choice at the counter: do you buy the rental company’s collision damage waiver (CDW) or rely on your credit card? The daily cost for the rental company’s CDW typically runs between $20 and $30 or more, which can quickly add up on a week-long trip. Many travellers don’t realise their credit card may already cover this, but the rules around vehicle value, rental duration, and where you’re driving matter a lot.

Here’s what you actually need to know. Credit card CDW is the most used insurance benefit among cardholders in Canada, according to research that reviewed policies from 70 different credit cards. But the coverage varies in important ways — vehicle value limits, how many days are covered, and which countries are excluded. Understanding those details before you reach the rental counter can save you from a surprise bill later.
I’ve looked through how these policies work so you don’t have to dig through the fine print yourself. Let’s walk through what matters most when deciding whether to decline that rental company offer. If you’re also sorting out other coverage questions, you might find our guide on medical payments coverage for car insurance useful for the bigger picture.
The central concept here is the collision damage waiver, often called CDW. It’s not technically insurance — it’s a waiver that the rental company agrees not to charge you for damage to their vehicle. When your credit card offers CDW coverage, it reimburses you for those charges instead.
What I tend to notice is that people assume credit card CDW works the same across all cards. It doesn’t. The differences in vehicle value caps, rental days, and country exclusions can leave you exposed if you don’t check your specific policy.
What happens when you misunderstand rental car CDW coverage
The biggest risk is a large, unexpected bill. One documented case involved a $4,424.50 charge because a credit card didn’t cover truck rentals — the cardholder assumed all rentals were included. That kind of surprise can derail a trip and strain your budget.
Beyond the financial hit, there’s the question of liability. Credit card CDW covers damage to the rental vehicle, but it does not provide third-party liability insurance. If you cause an accident that injures someone or damages their property, your credit card won’t help. The rental company’s default liability coverage in Canada is often only $200,000, which many brokers consider too low. They typically recommend $1–$2 million in liability coverage.
Another gap people miss is loss of use. If the rental company claims they lost income while the damaged vehicle is being repaired, they may bill you for those days. Some credit card CDW policies cover this, but not all. The endorsement known as OPCF20 (or QFE20/SEF20 in other provinces) provides loss of use coverage for your own vehicle when it’s in the shop, but that’s a separate matter from rental car coverage.
I’d say the most practical step is to print the insurance section of your credit card policy and carry it with you to the rental counter. Include the issuer’s support phone number so you can call if there’s a question. A Garmin X110 dash cam can also help document any incidents, providing clear video evidence if a dispute arises about damage.
Common mistakes people make with rental car CDW in Canada
Assuming all credit cards offer the same coverage
Researchers reviewed 70 credit cards in Canada and found that while CDW policies mirror each other in many ways, there are minor but important variations. Some cards cap coverage at $65,000 MSRP, others at $85,000 or $100,000. One card doesn’t impose any maximum MSRP limit at all. The number of covered rental days ranges from 15 to 30. Limited production vehicles — those with fewer than 2,000 or 2,500 units — may also be excluded. You have to check your specific card’s terms.
Thinking CDW covers everything
Credit card CDW covers damage to the rental vehicle from accidents, vandalism, and theft. It does not cover your personal belongings inside the car. Personal Effects Coverage (PEC) is a separate add-on that typically covers up to $500 with a $25 deductible per person, costing $2–$5 per day. If you have home or renters insurance, your belongings may already be covered away from home, so PEC might be unnecessary.
Ignoring travel advisories and sanctions
Canadian government travel advisories or sanctions can affect whether your credit card CDW applies. If the government advises against travel to a certain country, your coverage may be void. Always check current advisories before you travel and before you decline the rental company’s CDW.
Forgetting about personal accident insurance
Personal Accident Insurance (PAI) covers accidental death and dismemberment for the driver and passengers. It typically provides up to $100,000 for the driver and $10,000 per passenger, costing $7–$10 per day. If you have life insurance or other accident coverage through work, you may not need this. But if you don’t, it’s worth considering — especially if you’re driving in unfamiliar conditions.

How to use your credit card CDW and what to watch for
Declining the rental company’s CDW at the counter
When you pick up the rental car, the agent will offer you their CDW. To use your credit card coverage, you simply decline that offer. No paperwork is needed at that moment — just say no. But you must use the credit card that provides CDW to pay for the entire rental. If you use a different card or mix payment methods, the coverage may not apply.
Before you travel, call your credit card issuer or check your policy online. Ask specifically: what is the maximum MSRP covered, how many rental days are included, and are there any country exclusions? Write down the answers and keep them with your rental documents.
What happens if there’s damage
If the rental vehicle is damaged, stolen, or vandalised, you need to file a claim with your credit card’s insurance provider. The process typically involves:
- 1Report the incidentContact the rental company immediately and file a police report if required. Get a copy of both reports.
- 2Call your credit card issuerUse the support number you printed earlier. They’ll tell you what documents they need — typically the rental agreement, police report, photos of damage, and repair estimates.
- 3Pay and submitYou may need to pay the rental company’s charges first, then submit the receipts to your credit card insurer for reimbursement. Keep all original documents.
Having a AZDOME M660 360° dash cam installed can provide multi-angle footage that strengthens your claim if there’s a dispute about how the damage occurred.
Countries where credit card CDW doesn’t work the same way
In Ireland, Italy, and Jamaica, local laws require you to purchase CDW from the rental company. You cannot decline it. In those cases, your credit card may cover the deductible on the rental company’s policy — but only if your card’s terms specifically allow it. Check before you travel. If you’re renting in one of these countries, budget for the rental company’s CDW cost.
Liability coverage: the piece most people miss
Credit card CDW is not liability insurance. If you cause an accident that injures someone or damages property, you need separate coverage. Your personal auto insurance may extend to rental cars, but this varies by province and policy. The endorsement OPCF27 (or QEF27/SEF27) extends your liability coverage to non-owned vehicles you drive. If you don’t have this, the rental company’s default liability is often only $200,000 — which many experts consider insufficient. You can purchase additional liability from the rental company for $15–$30 per day.

Know your coverage before you sign at the counter
The rental counter is the worst place to learn what your credit card CDW does and doesn’t cover. The agent is there to sell you their product, not to explain your card’s fine print. Taking 15 minutes before your trip to call your card issuer and read your policy can save you hundreds or thousands of dollars.
