If your business is about to order equipment, upgrade its technology or approve a major fit-out, move the tax conversation ahead of the purchase order. On September 15, 2026, Prime Minister Mark Carney announced the proposed Productivity Mega Deduction, a measure that would broaden access to immediate expensing and let businesses deduct the full eligible cost of more assets in the first year those assets become available for use. For Canadian-controlled private corporations, or CCPCs, this could change the numbers behind an investment already on the table, though the proposal itself is not limited to CCPCs.
The reason to look at this now is practical. Once you have signed the contract, committed the cash and accepted a delivery schedule, there may be fewer decisions left to adjust. The five items below are what Ontario business owners should review before committing.
One caveat before we get into them. As of September 17, 2026, this measure remains a proposal supported by draft legislation. Confirm the final rules before claiming a deduction.
1. Review the purchases already in your plan
Start with what the business actually needs. Replacement equipment, a technology upgrade, or assets that could improve capacity are the honest starting points. Do not turn an unplanned purchase into a priority simply because there is a tax headline.
Once you have that list, layer the proposal on top. The Finance Canada backgrounder proposes permanent immediate expensing for most eligible depreciable property acquired on or after September 15, 2026, which makes your existing capital budget a useful place to start. Pull together the quotes you are considering and ask your accountant which of them would receive different treatment under the proposal and which already qualify for accelerated deductions. A new announcement does not necessarily create a new benefit for every asset.
2. Check the asset before assuming it qualifies
A business purchase is not automatically an eligible purchase. Buildings and additions, goodwill and certain other intangible assets are excluded from the broad new measure, and vehicles carry additional restrictions. The draft legislation sets out the full definitions and exclusions.
The classification of what you are buying matters more than it might seem. For a renovation, ask the contractor to itemize the work, because equipment, leasehold improvements and structural building work should not be lumped together as one interchangeable expense. Their tax treatment differs. The same care applies to used equipment, where the seller and ownership history are part of the eligibility review. Finance Canada identifies restrictions involving prior ownership by the taxpayer or a non-arm’s-length person and tax-deferred transfers.
Send the quote and full asset description to your accountant before signing. “It is for the business” is the start of the eligibility discussion, not the conclusion.
3. Put delivery and installation beside your year-end
The date money leaves your bank account is not the only date that matters. An asset generally needs to become available for use before capital cost allowance (CCA) can be claimed, and delivery, installation and readiness all affect that timing. A deposit alone does not settle it, and the CRA’s available-for-use guidance explains the rules in detail.
For a purchase you are considering now, ask the supplier when the asset will be delivered, installed and ready to operate, then compare that schedule with your corporation’s fiscal year-end. Do not assume your business follows the calendar year. And while the proposal is described as permanent rather than a limited-time offer, the urgency here is to review the timing while you can still influence it, not to rush the decision. Projects already underway also need a separate check of the draft’s transitional rules.
4. Calculate the benefit without confusing a deduction with a refund
A full write-off does not mean the government pays for the asset. A deduction reduces taxable income, but the cash benefit depends on your tax position, and the business still has to fund the purchase itself.
To illustrate, suppose a corporation has $300,000 of taxable income before this deduction and claims $50,000 for a fully eligible asset. With no other adjustments, taxable income falls to $250,000. That is not a $50,000 tax refund. It is a $50,000 reduction in what gets taxed, and the actual tax saved depends on the corporation’s rate and circumstances.
The useful comparison, then, is the proposed treatment against the deduction already available under existing rules. Include financing costs, cash reserves and expected income in the calculation. If the corporation has losses, an immediate deduction may not produce an immediate cash benefit. CCA is also generally discretionary, so a larger claim now leaves less undeducted cost for later years. The CRA’s explanation of capital cost allowance is a useful starting point here. Ask whether claiming the maximum fits your business’s forecast, rather than assuming it always does.
5. Have the planning conversation before the purchase is final
To have a real conversation with your accountant, give them enough to work with. That means the quote, the seller’s details, whether the asset is new or used, the expected delivery and installation dates, and your current income forecast. If you are choosing between buying now and buying later, ask for a side-by-side tax and cash-flow comparison, and include the operational reason for the purchase alongside the numbers. A deduction should support a sound investment decision, not replace one.
Ontario owners have one more piece to layer in. The tax-rate assumptions in your forecasts may still be running on last year’s numbers. Our article on the Ontario small-business rate cut walks through what changed and why it matters for your remuneration and forecasting decisions. The rate applicable to your specific corporation still needs to be confirmed.
What this means for your next purchase
You do not need to rush out and buy something. You do need to revisit the numbers if a significant purchase is already moving toward approval. That is where your accountant at SHARP & Associates comes in. We work with owners in Oakville, Burlington, Milton, Mississauga and across the GTA to connect tax planning to business decisions, and we can review the proposed asset, timing and cash-flow impact before the commitment is made.
