You are at the dealership, and the salesperson asks the question every Durham business owner faces: lease or finance? The monthly payment is only half the story. The other half is what the CRA lets you write off, and that is where the real money hides.
Key takeaways
- In 2026, a business can deduct lease payments up to $1,100 per month before tax, or claim capital cost allowance on a financed passenger car capped at $39,000 (before HST).
- Loan interest on a financed vehicle is deductible up to $350 per month in 2026.
- A new zero-emission vehicle bought for business can qualify for a 55% first-year write-off in 2026, up to a $61,000 cost ceiling, far larger than any lease deduction.
- On a $45,000 car, a typical Canadian lease runs about $550 to $750 per month including tax, and the "1.5 rule" says roughly $675 (1.5% of MSRP) is the top of a fair deal.
- Leasing tends to win if you swap cars every 3 to 4 years or drive an expensive vehicle. Financing tends to win if you keep the car 5 to 6 years or buy an EV.
What is the difference between leasing and financing a car?
The difference between leasing and financing a car comes down to one word: ownership. When you finance a vehicle, you borrow money to buy it. Each payment on the car loan chips away at the balance and builds equity in the car, and once the loan is paid off the vehicle is yours to keep.
Leasing works differently. You do not buy the car. You pay for the vehicle's depreciation during the lease, plus a finance charge, over a fixed lease term. At lease end you hand the vehicle back, or you buy it out at a price set in the lease agreement. In plain terms, financing a car is buying on instalments, while leasing is closer to renting a car for a few years.
How does leasing a car work in Canada?
A typical car lease usually runs 24 to 48 months. Your monthly lease payments cover two things: the vehicle's depreciation during the lease term, and interest built into the deal through a number called the money factor. Because you only pay for the portion of the vehicle you use up, the monthly lease payment is lower than financing the same car.
At the start of the lease the dealer sets a residual value: what the car is worth at the end. A higher value of the car means a lower monthly payment. Leases also come with kilometre limits, and going over means per-kilometre charges when you return the car. You will also pay for wear and tear beyond normal use.
When you reach the end of your lease you have three options: return the vehicle and walk away, buy the car at the residual price, or lease a new car and start again. That last option is why leasing appeals to owners who like to drive a new car every few years. Can you lease a car in Canada with bad credit? Sometimes, but expect a larger down payment and a higher money factor, which pushes the payment up.
How financing a car works when you buy
When you finance a vehicle, you take out a car loan under a finance agreement, usually make a down payment, and pay the vehicle off over a set term. Once the loan is done you own the car outright. There are no kilometre limits and no wear-and-tear charges, and because you eventually own the car, you can sell it whenever you like. The monthly payment is higher than a lease, but every dollar builds equity, and when you keep the car after the loan is paid off you drive for the price of fuel, insurance and maintenance. The same logic applies to a used car, though the interest rate is often higher.
Lease vs finance a car: a side-by-side cost comparison
Here is how leasing and financing stack up on the factors that change the cost of owning a vehicle, whether you are leasing or buying.
| Factor | Leasing | Financing (buying) |
|---|---|---|
| Monthly payment | Lower | Higher |
| Upfront cost | Low (first payment plus fees) | Down payment usually required |
| Ownership at the end | None; return or buy the car | You own the vehicle |
| Kilometre limits | Yes, with overage fees | None |
| Depreciation risk | You pay depreciation during the lease only | You absorb the resale value |
| Best if you | want a new car every 3 to 4 years | keep the car 5 years or more |
| Business tax treatment | Deduct lease payments (capped at $1,100/mo) | Claim CCA (capped $39,000) plus interest ($350/mo) |
Over a short hold, leasing usually costs less month to month. Over a long hold, financing wins, because the payments end while you keep driving the same vehicle, and the cost of financing drops to zero once the loan is repaid. How each option is deducted, covered below, can tip the balance either way.
How much is a lease on a $45,000 car in Canada?
For a $45,000 car, expect a monthly lease payment of roughly $550 to $750 including tax on a 36 to 48 month lease. The range depends on the residual value (usually 50% to 60% of the price), the interest rate baked into the money factor (around 5% to 7%), your down payment, and your province. A representative Ontario example, with a small discount and modest cash down, lands near $585 before tax and about $660 a month once you add 13% HST.
You can sanity-check any quote with the "1.5 rule." Divide the monthly lease payment by the vehicle's MSRP. About 1% of MSRP is an excellent deal, roughly 1.25% is strong, and around 1.5% is the top of a fair deal. On a $45,000 car, 1.5% works out to about $675 a month. If a quote sits well above that with little cash down and standard kilometres, the lease program is probably weak.
How to write off a car in Canada
This is where a lease-or-finance decision stops being about the sticker and starts being about your return. If you use a vehicle for business, whether you are self-employed or run a corporation, the CRA lets you deduct part of the cost. Everything is prorated by your business-use percentage, so a clean mileage logbook is the foundation of every claim. Good bookkeeping is what turns a vehicle into a defensible deduction.
Writing off a leased vehicle
Lease payments are an operating expense. You deduct them in the year you pay them, capped at $1,100 per month before tax in 2026, then multiplied by your business-use percentage. Insurance and maintenance bundled into a lease are pulled out and deducted separately, so they do not eat into the $1,100 cap. If you are registered for HST, your input tax credit is also based on that cap, which works out to a maximum of about $143 a month in Ontario at 13%. For an expensive lease, a value-based restriction (CRA's Chart C worksheet) can cut the deduction below the cap, so the sticker price of a luxury vehicle still matters. Our tax services team runs this math before you sign.
Writing off a financed vehicle: capital cost allowance and interest
When you finance a vehicle you deduct two separate things. The first is capital cost allowance, or CCA, the tax version of depreciation. Which class the car lands in depends on what it cost. A passenger car that cost $39,000 or less before HST in 2026 goes in Class 10, written off at 30% on a declining balance. A pricier car, one that cost more than $39,000, goes in its own Class 10.1, where the capital cost you can claim is capped at that $39,000 limit plus HST, again at 30%. Either way the half-year rule applies in year one, so you claim only half of that 30%, about 15% of the cost, in the first year. The second deduction is loan interest, part of your finance costs, capped at $350 per month in 2026.
Electric vehicles are the big exception. A zero-emission vehicle goes in Class 54, with a higher $61,000 ceiling, and a new EV bought for business and available for use in 2026 qualifies for a 55% first-year write-off. That single rule is often the deciding factor, because no lease deduction comes close. You can read the current classes on the CRA's capital cost allowance page and the annual limits in the Finance Canada 2026 announcement.
One more point most drivers miss: what happens when you sell. A Class 10.1 vehicle sits in its own class, so on sale there is no recapture and no terminal loss, and you can still claim half a year of CCA in the year you dispose of it. That is a genuine advantage of buying and holding. An EV in Class 54 is pooled, so selling it can trigger recapture that pulls income back onto your return.
A Durham worked example: lease vs finance the same SUV
Picture a contractor based in Whitby who uses a vehicle 80% for business and pays 13% Ontario HST. She is choosing between leasing and financing the same $45,000 SUV, and the numbers decide it.
If she leases at $600 per month before tax, comfortably under the $1,100 cap, she deducts $600 times 12 times 80%, or $5,760, every year she keeps leasing. Simple and steady.
If she finances the same SUV, the numbers front-load. Her CCA base is the $39,000 cap plus 13% HST, or $44,070. The half-year rule limits year one to 15%, which is $6,610, and at 80% business use that is $5,288. Add first-year interest of roughly $2,400 (under the $350 monthly cap), of which 80% is $1,920, and her year-one deduction is about $7,208 against $5,760 for the lease.
Financing looks better in year one, but CCA shrinks every year while the lease deduction stays flat, so over a 3 to 4 year cycle with frequent trade-ins the two options land close together. Over a 5 to 6 year hold, financing pulls ahead, and she exits her Class 10.1 vehicle with no recapture. Now change one detail. If she buys a $61,000 zero-emission SUV instead, the 55% first-year write-off puts about $68,930 of capital cost in play (the $61,000 cap plus HST), and at 80% business use she deducts roughly $30,329 in year one. No lease can match that.
Should the vehicle sit in your corporation?
If your corporation owns or leases the vehicle and you drive it personally, two taxable benefits land on your T4 slip. The standby charge is 2% per month of the original cost including tax for an owned car, or two-thirds of the lease payments for a leased car. On top of that, an operating expense benefit of 34 cents per kilometre of personal use applies in 2026 if the corporation pays running costs. Both can add up fast.
For most owner-managers, the cleaner option is to own or lease the vehicle personally and have the corporation reimburse a tax-free per-kilometre allowance: 73 cents for the first 5,000 kilometres and 67 cents after that in 2026. It has to be kilometre-based, because a flat monthly allowance is taxable in your hands. Before you title a vehicle in the company name, talk it through with a CPA. This is the kind of call our advisory team helps owner-managers get right, and the CRA sets out the rules on its automobile benefits page.
Pros and cons of leasing vs financing a car
Every driver weighs these differently, so here are the honest trade-offs on each side.
Pros of leasing a car:
- A lower monthly payment than financing the same vehicle.
- You get to drive a new car every few years, usually still under warranty.
- For a business, the deduction is simple: the lease payment, up to the cap.
Disadvantages of a lease car:
- You build no equity and own nothing at the end of the lease.
- Kilometre limits mean per-kilometre fees if you drive a lot.
- You pay for wear and tear beyond normal use.
- Ending a lease early is expensive, and you never stop having a car payment.
Pros of financing a car:
- You own the car outright and build equity with every payment.
- No kilometre limits and no wear-and-tear charges.
- Cheaper over the long run once the loan is paid off and you keep the car.
- A financed Class 10.1 vehicle exits with no recapture on sale.
Cons of financing a car:
- A higher monthly payment than a comparable lease.
- You absorb the resale and depreciation risk.
- A larger down payment is usually needed up front.
When it is better to lease or finance a vehicle
There is no single best option, only the one that fits how you drive and how your business is set up. Lease a car if you like a new car every 3 to 4 years, you want the lowest monthly payment and smoother cash flow, or you drive an expensive vehicle where buying would trap capital above the CCA cap.
Finance a vehicle if you keep vehicles 5 to 6 years or longer, you drive high kilometres, you want to own the car outright, or you are buying a new EV where the 55% first-year write-off is the biggest deduction on the table. The tax code caps both options for pricey passenger vehicles, so neither leasing nor financing is a loophole. The best option depends on your hold period, the vehicle's price against the caps, gas versus electric, and whether the vehicle belongs to you or your corporation.
