Quick answer: Canada has no Section 179. That deduction exists only in the United States. Canadian truck buyers claim capital cost allowance (CCA) instead. Heavy freight trucks rated over 11,788 kg usually go in Class 16 at 40%, and most other trucks go in Class 10 at 30%. Passenger-type vehicles go in Class 10.1, which has a cost ceiling. The proposed Productivity Mega Deduction would allow 100% immediate expensing for many trucks acquired on or after September 15, 2026, though some lighter vehicles are excluded. Whether you buy or lease, and when the truck is ready to work, decides what you can claim.

Key takeaways
- Section 179 is a U.S. Internal Revenue Code deduction. In Canada, trucks are written off through CCA classes set by the Canada Revenue Agency (CRA).
- CRA puts freight trucks acquired after December 6, 1991 and rated higher than 11,788 kg in Class 16, at a 40% declining balance rate.
- Most other trucks and motor vehicles fall in Class 10 at 30%. Passenger vehicles over the cost ceiling go in Class 10.1, with a $39,000 ceiling for vehicles acquired in 2026 (Department of Finance, January 2026).
- The Productivity Mega Deduction is proposed, not yet law. It would give permanent 100% expensing for most depreciable property acquired on or after September 15, 2026, with certain Class 10 and 10.1 vehicles excluded.
- The Accelerated Investment Incentive was reinstated by Bill C-15, which received Royal Assent on March 26, 2026 (law). It gives a larger first-year claim on property that does not get full expensing.
- With an equipment loan or conditional sale, your business owns the truck and claims CCA. With a true lease, you deduct the lease payments instead.
Why "Section 179" does not apply in Canada
A lot of Canadian owner-operators search for Section 179 because U.S. trucking content dominates the results. Section 179 is a U.S. federal rule. For 2026, it lets an American business expense up to $2,560,000 of qualifying equipment, with the limit phasing out once purchases pass $4,090,000. Canadian businesses filing with the CRA cannot use it.
The Canadian version of the same idea is capital cost allowance. Rather than one deduction cap, CCA sorts assets into classes. Each class has a rate, and you claim a share of the remaining balance each year. That balance is called undepreciated capital cost (UCC). Temporary and proposed incentives can speed this up, sometimes to a full write-off in year one.
If you run cross-border freight with a U.S. entity, the U.S. rules may matter for that entity. The Canadian company still files under Canadian rules. Our guide on Section 179 in Canada and CCA classes for equipment covers the comparison in more depth.
Which CCA class does your truck belong in?
The class depends on what the truck is designed to do and how heavy it is rated. Purchase price is only relevant for passenger vehicles. The table below summarises the classes most truck buyers run into.
| Vehicle type | Typical CCA class | Rate | What to watch |
|---|---|---|---|
| Freight truck or tractor rated over 11,788 kg | Class 16 | 40% | Must be designed for hauling freight; check the rating on the spec sheet |
| Lighter trucks, vans and most motor vehicles | Class 10 | 30% | Some pickups and vans count as passenger vehicles |
| Passenger vehicles over the cost ceiling | Class 10.1 | 30% | $39,000 ceiling for 2026 acquisitions; each vehicle in its own class |
| Zero-emission vehicles that would otherwise be Class 10 or 10.1 | Class 54 | 30% | $61,000 cap for zero-emission passenger vehicles |
| Trailers | Usually Class 10 | 30% | Confirm classification with your accountant |

Class 16: highway tractors and heavy freight trucks
Most long-haul tractors and heavy straight trucks used to move freight land in Class 16. The 40% rate is the highest of the common vehicle classes, which is part of why heavy trucks write down quickly on paper. Our article on claiming CCA on your purchased truck walks through the claim itself.
Class 10: work trucks, vans and vocational units
Service trucks, smaller delivery trucks and many vocational units sit in Class 10. A dump truck or concrete mixer may be heavy, but if it is not designed to haul freight, your accountant may place it elsewhere. Our Class 10 vehicle guide covers the details.
Class 10.1: pickups that count as passenger vehicles
A pickup used mostly to carry people, rather than goods or equipment, may be treated as a passenger vehicle. If its cost is above the ceiling, it goes in Class 10.1. For vehicles bought in 2026 the ceiling is $39,000 before tax, interest deductions are limited to $350 a month and lease deductions to $1,100 a month (Department of Finance, January 2026). Anything above the ceiling never becomes deductible.
How the incentives change your first-year claim
Under the basic rules, the half-year rule limits your claim in the year you buy. A Class 16 truck would get 20% of cost in year one rather than 40%. Several measures now change that. Some are law and some are still proposed.
| Measure | Status (Nov 10, 2026) | What it does for trucks |
|---|---|---|
| Productivity Mega Deduction | Proposed. Draft legislation released September 15, 2026; confirmed in Budget 2026 | 100% immediate expensing for most depreciable property acquired on or after September 15, 2026. Budget 2026 lists heavy freight trucks as an example. Certain Class 10 and 10.1 vehicles are excluded |
| Accelerated Investment Incentive (reinstated) | Law. Bill C-15, Royal Assent March 26, 2026 | A larger first-year claim, with the half-year rule set aside, for property that does not get full expensing |
| Zero-emission vehicle expensing | Law. Bill C-15 | 100% first-year expensing for eligible zero-emission vehicles, subject to caps |
| Basic CCA with half-year rule | Law | Half the normal rate in year one, then the full rate on the declining balance |
Which vehicles the Mega Deduction leaves out
PwC Canada's summary of the draft rules says the exclusion covers certain Class 10 and 10.1 vehicles. That includes passenger vehicles, rental vehicles, taxis and certain delivery vans or pickup trucks. The same summary says new vehicles of those types that are assembled in Canada are eligible. Property in excluded classes keeps the Accelerated Investment Incentive.
Used trucks can qualify too, with conditions. Blakes notes that the property cannot have been previously owned by you or by a person you do not deal with at arm's length. Before you buy a used unit late in the year, ask your accountant to check it against the draft. Our post on tax benefits of used commercial truck purchases has more on this.
An illustration, not a forecast
Take a hypothetical $150,000 Class 16 highway tractor, put into use in the same tax year it was bought. Under basic CCA with the half-year rule, the first-year claim is $30,000 (half of 40%). If the Productivity Mega Deduction becomes law as drafted and the truck qualifies, the first-year claim could be the full $150,000. The total deduction over the truck's life stays the same; expensing moves it into year one. Tax savings depend on your income and tax rate. A large first-year claim also lowers UCC, which can lead to recapture when you sell or trade the truck. Use our depreciation calculator or the ROI and tax calculator to model your own numbers.
Buying vs leasing a truck: who claims what
The financing structure decides who gets the tax deduction. Owner-operators ask us about this more than any other tax point.
- With an equipment loan or a conditional sales contract, your business is treated as the owner. You claim CCA (or immediate expensing) and deduct the interest portion of payments.
- With a true equipment lease, the lessor owns the truck. You deduct lease payments as an operating expense, subject to the passenger vehicle limits where those apply.
- A lease with a nominal buyout can be treated as a purchase for tax purposes. Read our guide on capital lease tax treatment before signing.
If full expensing becomes law, owning the truck may matter more to some buyers, because the full write-off goes to the owner. A lease can still suit businesses that want lower upfront cost or plan to turn units over often. Our comparison of CCA vs leasing sets out the trade-offs, and the loan vs lease comparison tool lets you test both.
Timing rules that trip up truck buyers
"Available for use" matters more than the purchase date
You can claim CCA only once the truck is available for use. A unit sitting at the dealer waiting for a body upfit, plates or safety certification may not qualify in the year you paid for it. If your fiscal year ends December 31, a truck delivered on December 30 but still unplated could miss the year.
Acquisition date for the Mega Deduction
The proposed deduction applies to property acquired on or after September 15, 2026. A deposit or signed order placed before that date could affect eligibility. Keep the purchase agreement, bill of sale and delivery records in one file.
Sales tax is a separate question
GST, HST and PST do not change your CCA class, but they do affect what you pay and what you can recover. See our guides on HST and GST when buying or leasing a truck in Ontario and PST on equipment by province.
What we see on real files
A few patterns come up again and again when truck buyers talk to us about tax timing. Owners often plan around a December write-off, then find the truck will not be road-ready until January. Buyers sometimes sign a lease expecting to claim CCA, without realising the deduction stays with the lessor. Newer owner-operators tend to focus on the write-off and pay less attention to the monthly payment against their actual freight revenue. Lenders look at that payment first. The files that move fastest have the spec sheet, bill of sale, bank statements and a clear plan for the truck ready from day one.
How financing fits with your tax plan
Through our network of over 50 lenders, we arrange truck and trailer financing for owner-operators and fleets across Canada. Lenders usually look at time in business, credit, cash flow, the truck's age and mileage, and your down payment. Startups generally need at least six months of revenue in business bank statements. Terms, rates and approval always depend on the lender's review.

FAQ
Can a Canadian business use Section 179 on a truck?
No. Section 179 is part of U.S. tax law. Canadian businesses claim capital cost allowance and any Canadian incentives that apply, such as the reinstated Accelerated Investment Incentive or, if enacted, the Productivity Mega Deduction.
Is a semi truck Class 10 or Class 16?
A tractor or truck designed to haul freight and rated over 11,788 kg is generally Class 16 at 40%. Lighter trucks are usually Class 10 at 30%. Your accountant should confirm based on the truck's specifications and use.
Is the Productivity Mega Deduction law yet?
Not as of November 10, 2026. Draft legislation was released on September 15, 2026, and Budget 2026 confirmed the plan. If enacted as proposed, it applies to eligible property acquired on or after September 15, 2026.
Can I claim CCA if I lease my truck?
Usually not with a true lease. The lessor owns the truck and claims CCA, and you deduct lease payments. A lease that works like a purchase, such as one with a nominal buyout, may be treated differently.
Does a used truck qualify for immediate expensing?
Under the draft rules, a used truck can qualify if neither you nor a non-arm's-length person owned it before, and it meets the other conditions. Confirm with your accountant before you buy.
