The Truth About 0% Car Financing in Canada: When It's Real and When the Rebate Wins
By Jordan Ellis · Published
Quick Answer
0% car financing in Canada is real but never free: choosing it almost always means giving up the manufacturer's cash rebate, typically $3,000-$7,500. The right choice is pure math — compare interest paid at market rates against the forgone rebate. On a $40,000 car over 60 months, 0% financing saves roughly $6,400 in interest versus a 6% loan; a $5,000 rebate loses to it, but a $7,500 rebate wins. Expect a required credit score around 700+, terms often capped at 36-60 months, limited eligible models, and no negotiation on the selling price. Always price both options on the same vehicle before signing.
The ad says 0%. The truth says choose: the cheap loan or the cash rebate — never both. Here’s how to make that choice with actual numbers, using the auto loan calculator.
The fork in every showroom
Manufacturers subsidize sales two ways, and you pick one:
- Subsidized rate: 0–2.9% financing
- Cash rebate: commonly $1,000–$7,500 off, but you pay market rates (~6–8% in recent years)
Same car, same day, two different total costs. The only question that matters: is the interest you’d pay bigger than the rebate you’d lose?
The math on a $40,000 car, 60 months
| 0% financing | $5,000 rebate + 6% loan | $7,500 rebate + 6% loan | |
|---|---|---|---|
| Amount financed | $40,000 | $35,000 | $32,500 |
| Monthly payment | $667 | $677 | $628 |
| Total paid | $40,000 | ~$40,600 | ~$37,700 |
Small rebate → 0% wins by ~$600. Big rebate → the cash wins by ~$2,300. The answer flips at the rebate level, the term, and your market rate — which is why you run your numbers in the calculator, in the dealership, on your phone, before anyone prints paperwork. The lease vs finance guide covers the third fork they won’t volunteer.
The fine print that decides eligibility
- Credit: ~700+ (tier 1). The ad rate is for the file, not the public — check your score first (how scores work)
- Terms capped: 0% usually stops at 36–60 months; the 84-month version quietly isn’t 0%
- Model-restricted: the offer lives on the trim they need to move, not the one on the poster
- Price freeze: 0% deals often come with a no-haggle sticker — negotiate the price before mentioning financing
- Down payment: some offers require 10–20% down to qualify
The move that beats both
If you have cash: take the rebate and pay cash — rebate wins with zero interest cost at all. If you have cash but like liquidity: take the rebate, finance at market, and park the difference in a high-interest account or GIC (laddered) — arbitrage the dealer subsidy against your own yield.
And whatever the fork, hold the line on total cost: how much car you can afford is a function of your income, not their financing menu — and the car affordability calculator keeps the 20/4/10 rule honest while the finance office does its best work on you.
