Buying a Car Across the Windsor–Detroit Border: The Complete Guide

9 min read · Updated August 19, 2026

Few places in North America make cross-border car shopping as natural as Windsor and Detroit. The two cities are minutes apart, yet they sit in different countries — which means a buyer in Windsor, Ontario can often find a better price, a rarer trim, or a specific model just across the river in Detroit, Michigan, and vice-versa.

Buying across the border is very doable, but it is not the same as buying down the street. This guide walks through how it actually works in both directions, what it costs, and the paperwork you need — so you can shop the wider Windsor–Detroit market with confidence.

First: is the vehicle admissible?

Before anything else, confirm the specific vehicle can legally be imported into the destination country. Not every car qualifies. Canada and the United States each maintain their own standards, and a vehicle built to one country's requirements is not automatically admissible in the other.

For vehicles coming into Canada, Transport Canada's Registrar of Imported Vehicles (RIV) program publishes admissibility information by make, model, and year. For vehicles going into the United States, admissibility is governed by U.S. EPA (emissions), DOT/NHTSA (safety), and Customs and Border Protection (CBP). Always verify the exact VIN's status with the official agency before you pay for anything.

Direction 1 — Importing from the US into Canada

  • Confirm admissibility with the RIV program for that specific make/model/year.
  • Get a clear title and a bill of sale from the seller. A vehicle with a lien or a salvage/branded title can be complicated or ineligible.
  • Obtain a recall clearance letter from the manufacturer showing there are no outstanding safety recalls — Canada requires this.
  • Submit the vehicle's title to U.S. CBP at least 72 hours before export (this lead time is required at the border).
  • Pay the applicable duties and taxes on entry (see below), plus the RIV program fee.
  • Complete the federal RIV inspection within the required window after import, then the provincial safety and emissions requirements before you can plate it in Ontario.

Direction 2 — Importing from Canada into the US

  • Confirm the vehicle meets U.S. EPA and DOT/NHTSA standards (many Canadian-market cars do, but verify).
  • Provide the title and bill of sale; present the vehicle and paperwork to CBP at the port of entry.
  • Pay any applicable U.S. duty. Passenger vehicles manufactured in Canada, the U.S., or Mexico often qualify for duty-free treatment under CUSMA/USMCA when accompanied by proof of origin — confirm your vehicle's eligibility.
  • Register and title the vehicle in your state, meeting your state's inspection and emissions rules.

What it costs: duties, taxes, and fees

The exact numbers depend on the vehicle, its country of manufacture, and current rules, but the categories to budget for are consistent:

  • Duty — often $0 for qualifying North-American-built vehicles under CUSMA/USMCA with proof of origin; otherwise a percentage of the value.
  • Sales tax — GST/HST in Canada (collected on import and/or at registration); state sales/use tax in the U.S.
  • RIV program fee — a fixed fee for vehicles imported into Canada.
  • Possible federal levies in Canada on some vehicles (for example, an air-conditioning excise tax and, for certain fuel-inefficient models, a 'green levy').
  • Inspection and safety/emissions certification costs in the destination jurisdiction.

Paperwork checklist

  • Original title (clear, no undisclosed liens)
  • Bill of sale with the agreed price and both parties' details
  • Recall clearance letter (for import into Canada)
  • Proof of origin, if claiming duty-free treatment under CUSMA/USMCA
  • Government photo ID and, at the border, the vehicle itself for inspection

How RovaFi helps

The hardest part of cross-border buying is judging a car you can't stand next to. RovaFi is video-first: every listing is built around a real walkaround, so you can see the exact condition — interior, exterior, engine bay, and how it presents — before you commit to a trip across the border. Browse Windsor and Detroit inventory side by side, then coordinate the purchase and import directly with the seller.

Frequently asked questions

Is it worth buying a car across the Windsor–Detroit border?

It can be, when the price difference or the specific vehicle you want outweighs the import costs and effort. Because Windsor and Detroit are so close, the logistics are far simpler than a typical long-distance import — but you should still total up duties, taxes, fees, and inspection costs before deciding.

How long does it take to import a car across the border?

The border step itself is quick, but U.S. export rules require the title to be submitted to CBP at least 72 hours before the vehicle leaves, and Canada requires a federal inspection within a set window after import. Plan for at least a week end to end.

Do I have to pay duty on a car imported between Canada and the US?

Often not, if the vehicle was manufactured in Canada, the U.S., or Mexico and you can show proof of origin under CUSMA/USMCA. Vehicles built elsewhere may be dutiable. Taxes (GST/HST or state sales tax) and program fees still apply. Always confirm with the official agency for your specific vehicle.

This guide is general information, not legal or financial advice. Cross-border and registration rules change and vary by vehicle — confirm current requirements with the official agencies (Transport Canada’s RIV program, the CBSA, and U.S. Customs and Border Protection) before you buy or import.
