Buying a Car in Canada: Sales Tax, Trade-Ins and the Real Monthly Payment
The same $35,000 car costs a different amount in every province. How sales tax, your trade-in and the loan length change the real cost, with a table by province.

The sticker price of a car is only the start. Add the dealer's fees, sales tax and six years of interest, and the real cost changes a lot depending on your province and how you use your trade-in.
The same car in five provinces
A $35,000 vehicle, $899 in fees, $3,000 down, 72-month loan at 6.99%:
| Province | Tax | Tax paid | Monthly payment | Total cost |
|---|---|---|---|---|
| Alberta | 5% | $1,795 | $591.33 | $45,576 |
| Ontario | 13% | $4,667 | $640.28 | $49,100 |
| Quebec | 14.975% | $5,376 | $652.36 | $49,970 |
| British Columbia | 12% | $4,308 | $634.16 | $48,660 |
| Nova Scotia | 14% | $5,026 | $646.40 | $49,541 |
Your trade-in cuts the tax too
At a dealer, most provinces only tax the price minus your trade-in. In Ontario, a $10,000 trade-in lowers the tax from $4,667 to $3,367. If the tax were on the full price, you'd pay $1,300 more. Selling your old car privately might get a better price, but do the maths with that tax saving included.
The long-loan trap
- Over 72 months, total interest is about $8,534 in Ontario.
- Over 48 months, the payment rises to $899.39 but interest drops to $5,605.
- With a long loan you can owe more than the car is worth for years.
Before you sign
- Negotiate the vehicle price before you talk about financing.
- Ask for the APR in writing and compare it with your bank or credit union.
- Turn down add-ons (extended warranty, protection packages) you don't want: they're often financed with interest.
