Productivity Mega Deduction Canada: What Ontario Owners Must Know

On September 15, 2026, Prime Minister Mark Carney proposed the productivity mega deduction Canada at the Canada Investment Summit in Toronto. The proposal would let businesses deduct 100% of the cost of most eligible equipment in the year it becomes available for use. For Ontario business owners planning capital purchases, the timing could matter. Here is what was proposed, what is still uncertain, and what to do before year end.
What the Productivity Mega Deduction Canada Proposal Would Do
The Department of Finance released draft legislative proposals on the same day as the announcement. If enacted, the measure would provide permanent 100% first-year expensing for a wide range of new or used depreciable property. It would also cover Canadian development expenses. Permanent matters here. Earlier accelerated measures were temporary, with fixed end dates.
The government estimates about two-thirds of investment in capital assets would become eligible. That compares with roughly 15% under the Productivity Super-Deduction announced in Budget 2025. The proposal would also lower Canada’s marginal effective tax rate on new business investment from 13% to 6.4%, according to the Department of Finance.
None of this is law yet. The announcement is a proposal with draft legislation. Parliament has not passed it. Do not make purchase decisions on the assumption that it will pass exactly as proposed. Speak to your accountant before you act.
Immediate Expensing in Canada: How It Differs from Capital Cost Allowance
Under the capital cost allowance 2026 rules, you cannot deduct the full cost of most capital assets in the year you buy them. Instead, the CRA assigns each asset to a class with a prescribed rate. You then claim a percentage of the cost each year until it is fully written off. For example, general business equipment is commonly written off at 20% per year, and motor vehicles at 30%.
Immediate expensing in Canada would change the timing, not the total. You would deduct the full cost in the first year the property becomes available for use. For a profitable business, moving the deduction forward can improve after-tax cash flow. It is a timing benefit, not a grant or rebate.
Capital Cost Allowance vs the Proposed Productivity Mega Deduction
| Feature | Capital Cost Allowance (current law) | Productivity Mega Deduction (proposed) |
|---|---|---|
| How the cost is deducted | A prescribed percentage each year by CCA class, spread over several years | 100% of the cost in the year the property becomes available for use |
| Coverage | All depreciable property | About two-thirds of capital asset investment |
| Permanence | Permanent system | Would be permanent if enacted |
| Status | Law | Proposal; Parliament has not enacted it |
What Property Would Qualify
The government named a broad set of examples. These include software, computer equipment, vehicles, patents, and manufacturing equipment. Later federal releases added fibre-optic cable, greenhouses, mining property, oil and gas pipelines, research and development, aircraft, rail track, bridges, and roads.
What May Not Qualify
The federal backgrounder also flags exclusions. Certain buildings, some intangible property, specified vehicles, and regulated natural gas distribution pipelines are carved out. Restrictions may also apply to used property and to purchases between related parties. Eligibility will turn on the draft legislation and the facts of each purchase.
Who Benefits Most in Ontario
As a business investment tax incentive in Canada, this proposal favours businesses that regularly invest in productive assets. Manufacturers upgrading machinery, professional firms refreshing computer systems and software, and trades or logistics businesses renewing vehicles would see the most direct effect.
There is one condition that matters. A deduction only saves tax if the business has taxable income to offset. A company with losses may get less immediate benefit. Your accountant can model whether accelerating a purchase actually helps your situation.
Should You Accelerate an Equipment Purchase Before Year End?
This is the question behind every equipment tax deduction Canada conversation this fall. The draft proposals apply to eligible property acquired on or after September 15, 2026. The deduction would then be claimed in the year the property becomes available for use.
Available for use is a specific concept. CRA guidance generally treats property as available for use when it is first used to earn income. It can also qualify when delivered and capable of producing a saleable product or service. A server that arrives in December but is not installed until January may raise a timing question. Keep records of delivery, installation, and first use.
If the measure is not enacted, the fallback is the existing system. You would claim capital cost allowance at the normal class rates. Assets that do not qualify would still get an enhanced first-year deduction under the Accelerated Investment Incentive, according to the federal backgrounder.
What to Do While You Wait
- List every capital purchase you are considering before your next year end, with expected delivery dates.
- Record acquisition dates and in-service dates for anything you buy now, in case the proposal passes as drafted.
- Ask your accountant to model both outcomes, with and without immediate expensing.
- Do not sign a purchase or financing agreement solely because of this proposal.
- Review whether existing incentives, such as the Budget 2025 super-deduction, already cover the asset.
The Bottom Line
The productivity mega deduction Canada proposal is the most significant expansion of immediate expensing in years. If enacted, it would let many Ontario businesses write off equipment, technology, and vehicles in year one, permanently. Until Parliament acts, treat it as a planning scenario, not a promise. The businesses that benefit most will be the ones that plan now and document everything.

Frequently Asked Questions
Is the Productivity Mega Deduction law yet?
No. It exists as draft legislative proposals released on September 15, 2026. Parliament has not enacted it. Treat all details as conditional until that changes.
When would the deduction apply?
As drafted, it would apply to eligible property acquired on or after September 15, 2026. The deduction would be claimed in the taxation year the property becomes available for use.
Does it cover used equipment?
The proposal covers new or used depreciable property, but restrictions may apply to used property and related-party acquisitions. Confirm eligibility against the final legislation before you rely on it.
How is this different from the 2025 Productivity Super-Deduction?
The super-deduction provides immediate expensing for about 15% of capital asset investment, focused on narrower categories. The mega deduction would extend permanent immediate expensing to about two-thirds of such investment.
Should I buy equipment now to claim the deduction?
Do not assume the proposal will pass in its current form. Make the purchase decision on business grounds, document your dates, and speak to your accountant about the tax timing.
