Taking a rental car across the Windsor–Detroit border
You can usually take a rental car across the Windsor–Detroit border, but the rental company sets the rules, and they vary by company, location and vehicle. A few minutes at the counter saves you from being turned back at the booth or voiding your coverage.
The short version
- Tell the counter you will cross the border, before you drive off. Some companies need advance consent.
- Carry the rental agreement, and ask for a Canadian non-resident insurance card if you rented in the U.S.
- Everyone in the car needs border ID: see what ID you need.
- Canadians bringing a U.S. rental into Canada must declare it; GST/HST may apply per week.
What the big rental companies say
| Company | U.S. rental into Canada | What to do |
|---|---|---|
| Enterprise, National, Alamo | Generally allowed; U.S. rentals can be driven in Canada and Canadian rentals in the U.S. | Mention it at pickup; some vehicle classes are excluded |
| Avis, Budget | Allowed with consent, on a limited set of vehicles | Ask for the free Canadian non-resident insurance card |
| Hertz, Dollar, Thrifty | Varies by location | Check the rental terms for your pickup location |
| Sixt and smaller companies | Often restricted or needs written permission | Get permission in writing before you book |
Summary of published policies; the terms on your own rental agreement are what count. Large passenger vans (15 seats) are treated as commercial vehicles in Canada.
Documents to have at the booth
- Border ID for everyonePassport, passport card, NEXUS or enhanced licence
- Rental agreementWith you listed as a driver
- Proof of insuranceCanadian non-resident insurance card for U.S. rentals
- Permission to crossNoted at pickup if the company requires it
Officers may ask whose car it is and how long you are staying. Saying it is a rental and showing the agreement is enough.
Canadians driving a U.S. rental into Canada
Under CBSA Memorandum D2-4-1, a resident of Canada may temporarily import a U.S.-based rental vehicle for non-commercial use. Declare it at the booth. If GST/HST applies, it is charged for every week or part of a week the car stays in Canada, based on a fixed value for the vehicle class, and the reduced treatment covers stays of up to 30 days. Check your own auto insurance or credit card coverage too, since U.S. rental insurance is designed mainly for U.S. residents.
Before you go
- Check the live wait times and pick the quickest crossing.
- Rentals rarely have a toll transponder for the border, so plan to pay at the booth: see tolls compared.
- Fill up on the U.S. side if you are returning the car there: gas is usually cheaper in Michigan.

Common questions
Can I drive a rental car from Detroit to Windsor?
Usually yes, but rules depend on the rental company and location. Tell the counter you plan to enter Canada when you pick up the car, ask for a Canadian non-resident insurance card, and keep the rental agreement with you at the border.
Can a Canadian drive a U.S. rental car into Canada?
Yes, for non-commercial use. CBSA allows residents of Canada to temporarily import a U.S.-based rental vehicle. Declare it at the booth: GST/HST can be charged for each week (or part of a week) the car is in Canada, and the reduced treatment applies to stays of up to 30 days.
Can I take a Canadian rental car into Michigan?
Generally yes, with the rental company's permission. Bring the rental agreement; CBP can turn back a driver who cannot show it.
Can I return a U.S. rental car in Windsor?
One-way rentals across the border are harder to find and often cost more. Many companies only allow cross-border returns at certain locations, so book the one-way trip in advance rather than assuming you can drop the car off.
