Productivity Mega Deduction: What It Means for Canadian Small Business Owners (2026)

The Productivity Mega Deduction is a proposed federal rule that would let a business deduct 100% of the cost of most equipment in the year it’s put to use, instead of writing it off over many years. The Department of Finance announced it on September 15, 2026, and it covers property acquired on or after that date. The draft has no dollar cap and Ottawa has pitched it as permanent. It’s still draft legislation, though, so plan around it but don’t treat it as law yet.

What the Productivity Mega Deduction changes

Normally you deduct equipment a slice at a time through capital cost allowance. Take $100,000 of warehouse racking. Under the regular rules you’d deduct about $30,000 in the first year and the rest would trickle out over the years after. Under the proposal you’d deduct the full $100,000 in the first year the racking is available for use.

So this is a timing benefit. The total deduction over the life of the asset is the same $100,000 either way, and you get it sooner. At a small business tax rate of roughly 11% to 12% (about where Ontario and Alberta sit), the year-one tax saving goes from about $3,500 to somewhere between $11,000 and $12,000. Corporations taxed at the general rate save roughly twice that.

You’re still spending the other $88,000 or so.

What qualifies and what doesn’t

The draft starts from everything and carves out exceptions. Machinery, computers, software and shop tools are all in. For an online seller that means warehouse racking, a forklift, packing equipment and office tech. Leasehold improvements (the fit-out you pay for in rented space) look to be covered too, although major structural additions to a building are treated differently.

Buildings are out. So are certain vehicles, which get their own section below, along with franchises, licences and goodwill.

Inventory doesn’t count either, because it was never depreciable property. Stock you buy to resell is deducted as it sells, mega deduction or not. More on that in year-end inventory.

Used equipment can qualify, as long as neither you nor anyone you don’t deal with at arm’s length, such as your spouse or a related company, owned it before, and it didn’t come to you on a tax-deferred rollover.

The vehicle rule most people will get wrong

The draft shuts out most cars, SUVs, pickups and vans if they were used before you bought them or were assembled outside Canada. A new vehicle assembled in Canada can qualify, but where it was built is a question about the specific vehicle, so the badge on the hood won’t answer it. Finance says new zero-emission vehicles already get a full first-year write-off under the Budget 2025 rules, and the new draft doesn’t carve them out.

A forklift or a heavy freight truck isn’t caught by this exclusion, and neither is a trailer.

The existing cost ceiling on passenger vehicles stays. A $90,000 SUV doesn’t turn into a $90,000 deduction, and personal use of a company-owned vehicle still creates a taxable benefit. We cover that side in buying a car through your corporation.

Sole proprietors and partnerships get a narrower version

A corporation can claim the full deduction even when it pushes the company into a loss. That loss can generally be carried back up to three years, which can mean a refund of tax the company already paid.

Individuals can’t use the deduction to create a loss, and neither can partnerships that have individuals as members. For them the claim is capped at the income from the business that uses the asset. The unclaimed cost stays on the books and is deducted in later years under the regular, slower rules. If you’re unincorporated and a large equipment purchase is coming, that gap belongs in the incorporation decision.

Financing is fine, leasing usually isn’t

The deduction goes to whoever owns the equipment. Borrow from a bank or the dealer to buy it and you still deduct the full cost in year one, even though you’ve only paid a fraction of it in cash. For a business that’s tight on cash that’s a pretty good combination, since the tax saving shows up before most of the loan payments do.

A regular lease works the other way. The leasing company owns the asset and claims the write-off, and you deduct your lease payments as you make them. Some lease-to-own contracts are treated as purchases for tax, so have the paperwork checked before you assume which side you’re on.

Traps to check before you sign a purchase order

It isn’t law yet, and the details can change before anything passes. A purchase that only makes sense with the deduction is a bet on Parliament.

Paying for something doesn’t make it available for use. The deduction generally lands in the year the asset is delivered and ready to do its job, so equipment paid for in December that arrives in February belongs to the next year for a calendar year-end. Anything you acquired before September 15, 2026 is on the old rules, and if you ordered or put down a deposit before that date, check before counting on it.

Then there’s the back end. Sell a fully deducted asset later and the proceeds, up to what you originally paid, are generally added back to income.

Claiming the maximum isn’t always the best move either. The deduction is optional, and in a low-income year a smaller claim can leave you better off. The catch is that whatever you don’t claim in that first year moves to the regular, slower schedule.

Every December someone asks us what they should buy to save tax. We’d never tell a client to buy something for the deduction. Buy what the business needs, then get the timing right.

Frequently asked questions

Is the Productivity Mega Deduction law yet?

No. It’s draft legislation, released September 15, 2026, and it still has to pass Parliament. As drafted, it would apply to eligible property acquired on or after that date.

Do vehicles qualify for the Productivity Mega Deduction?

Some do. Under the draft, most cars, SUVs, pickups and vans are excluded if they were used before you bought them, or if they were assembled outside Canada. A new vehicle assembled in Canada can qualify, and the cost ceiling on passenger vehicles still applies.

Can a sole proprietor claim the Productivity Mega Deduction?

Yes, but only up to the income of the business using the asset, before depreciation, so it can’t create or increase a loss. Corporations don’t have that limit.

Do I get the Productivity Mega Deduction if I lease or finance equipment?

A financed purchase is treated like any other purchase because you own the asset. On a regular lease the leasing company owns it, so you deduct the lease payments and the leasing company gets the write-off. Some lease-to-own contracts count as purchases, so check the paperwork.
