Car financing is where a lot of Canadians lose money on a vehicle, not the sticker price. Longer terms, rolled-over balances and add-ons priced in the finance office all can end up costing you a lot.
Below, I’ll walk through five financing mistakes I see over and over and how to avoid every one of them.
Why this matters right now
Canadians are getting more cautious. Equifax Canada’s Q1 2026 report found new auto loans from manufacturer lenders fell nearly 5 per cent year over year to a three-year low, and Equifax pointed to rising insurance, maintenance, and fuel costs as the reason people are hesitating. The same report put insolvency volumes at their highest level since 2009.
Meanwhile, the Bank of Canada held its policy rate at 2.25 per cent in July for the sixth straight time. Cheaper borrowing isn’t coming to bail anyone out.
1. Shopping by the monthly payment
You walk in thinking “I can afford $500 more a month,” and the finance office happily makes that number work by stretching the term to 84 or 96 months. The payment fits, but the total cost can be a disaster.
The Financial Consumer Agency of Canada has a clean example: a $25,000 car at 5 per cent costs $1,974 in interest over 36 months and $4,681 over 84 months. Same car, more than double the interest, and you’re still paying for it when it’s seven years old and needs new brakes.
Decide on the total price you’re willing to pay before you talk about payments; then pick the shortest term you can handle. If the payment doesn’t fit, the answer is often a cheaper car, not a longer loan.
Your car payment as a share of take-home pay is one of the numbers that quietly decide your savings rate. I went through the numbers I track every month in a recent Blueprint Financial video, and it’s a useful way to see what a bloated payment is really costing you.
2. Rolling your old loan into the new one
Long loans create a second problem. FCAC notes a new car can be worth 25 per cent less after one year, but on an eight-year loan the balance barely moves in that time.
Trade in early and you owe more than the car is worth. That’s negative equity. It doesn’t only hurt on a trade-in: if the car is written off or stolen, your insurer pays what it was worth that day, not what you owe, and the loan balance is still yours.
The dealer will offer to roll the shortfall into your next loan. Now you’re paying interest on a car you no longer own, on top of the one you just bought, and the hole is deeper next time.
If you’re underwater, the boring answer is usually the right one: keep the car, keep paying, and let the balance catch up to the value. If you truly must sell, cover the gap with savings rather than financing it. Debt on a car you don’t have is the worst kind of debt.
3. Taking dealer financing without a comparison
The finance office is a profit centre. FCAC is blunt about this: a dealer doesn’t have to offer you the lowest interest rate they’ve been quoted. Ontario’s dealer regulator has warned that most dealers earn a commission from the lender they place you with and that some steer buyers toward the loan that pays the dealer more..
Try to get pre-approved at your bank or credit union before you set foot in the showroom. Now you have a rate to beat, and the dealer either beats it or you walk. Check your own credit report first, too, so no one can tell you your score is worse than it is.
That being said, promotional dealer rates can be genuinely good, especially on new vehicles. Just make sure you’re comparing the total cost of borrowing, not the headline number, and that the low rate isn’t tied to a longer term.
4. Financing the add-ons
Extended warranty, paint protection, rustproofing, fabric guard, tire and rim coverage, GAP insurance. Some are worth having. Almost none are worth financing at a markup over seven years with interest.
Every add-on that gets bundled into the loan inflates the principal, which makes the negative equity in mistake number two worse from day one. If you want protection, ask for the price separately, sleep on it, and see if your insurer or bank offers it for less.
My rule: nothing gets rolled into the loan that isn’t the car, the taxes, and the fees you legitimately can’t avoid.
5. Signing and never looking at it again
Most people treat a car loan like a fixed fact of life. It isn’t. The FCAC notes there’s generally no cooling-off period on car loans in most provinces, so you can’t reverse the loan. But you can often improve the loan afterward.
Two things to check once a year: First, does your loan allow prepayment without penalty? Many do, and even an extra $50 a month shortens the term and shrinks the negative equity window. Second, has your credit or the rate environment improved since you signed? If so, refinancing through a bank or credit union can lower your rate, particularly if you started with a high one.
And if you’re near the end of the loan with a reliable car, pay it off and keep driving it. The payment-free years are where the real savings live.
Final thoughts
None of these mistakes feel dangerous in the moment, which is exactly why they’re so common. Fix the first one, and most of the others take care of themselves: know your total price, choose the shortest term you can manage, and finance nothing you don’t have to.
