What a car actually costs in Ontario, once everything is in

Ask most people what their car costs and you get the payment. It is the number the dealer quoted, the number on the pre-authorised debit, the number that feels like the answer. It is also, for a typical Ontario buyer, about half of what the car is really taking out of the account each month.

The CAA puts the average total cost of owning a vehicle in Canada near $1,373 a month once every line is counted, and its own research finding is that Canadians are unclear about what a vehicle really costs. That gap is the whole problem. You can only budget for the number you can see.

So here is the full shape of the bill, line by line, with the Ontario figures we use and where each one comes from.

Insurance is the swing line

Every other cost in a car budget moves a little. Insurance moves a lot, and in Ontario it moves more than anywhere else in the country.

The published average annual premium in Brampton runs $3,341 to $3,802, the highest in the province. In Ottawa it is $1,886. That is $121 to $160 a month between two Ontario cities, for the same driver in the same car. A one-point difference in your loan rate does not come close to that.

Age moves it as hard. Ontario premiums improve materially after 25 with a clean record, and before that they can be brutal: reporting on young new male drivers in Toronto has put worst-case premiums above $13,000 a year. Premiums across the province rose about 4.45% year over year in 2026.

This is why we show insurance as a band rather than a number, and why the all-in figure carries that band with it. Only an insurer can quote you. Anyone who gives you one confident insurance number for a car you have not bought yet is guessing at your postal code.

Fuel, maintenance and the small stuff

Fuel is the most predictable line in the budget and the easiest to improve. We price Ontario regular gasoline at $1.70 a litre and drive the distance an average Canadian drives. An electric car charged at home off-peak runs on 9.8 cents per kWh, which is why the charging mix matters more than the car for anyone weighing an electric.

Maintenance we band by how old the car is rather than modelling it per part, because no Canadian per-model service dataset exists to do better and a banded number you can sanity check beats a precise one you cannot.

• Under five years old: $100 a month.
• Five to ten years: $125 to $150 a month.
• Ten years and up: $175 to $250 a month.

Ontario shop labour sits in the highest tier in the country alongside British Columbia, which is why the older bands climb the way they do. Winter tires belong in this line too. They are a real Ontario cost most calculators skip, and they usually earn an insurance discount that pays back part of themselves.

Licensing is the small honest one. Ontario removed plate sticker renewal fees in 2022, so for most owners the yearly cost of keeping the car legal is close to nothing. We still carry a line for the plate and permit work at purchase, spread across the term, because it is real money on the day.

What share of your income should this be

The old rule says total transportation should stay under 10% of gross income. Canadian commentary is blunt that with total ownership cost where it is, that rule is out of reach for all but the wealthiest households. We agree, so we use it as a guardrail rather than a gate.

Our own bands: at or under 10% of gross income is comfortable, up to 15% is realistic for most people, up to 20% is stretched, and above that carries a high risk of payment stress. Those are an editorial position rather than a law, and they are banded on the all-in number rather than on the loan payment, which is the part that makes them mean something.

If your number lands higher than you would like, the cheapest lever is almost never the loan rate. It is the city you insure in, the age of the car you maintain, and how much car you bought in the first place.
