Canada's Proposed Productivity Mega Deduction: What Businesses Should Be Thinking About
Article
The Government of Canada’s proposed Productivity Mega Deduction (PMD) represents one of the most significant changes to Canada’s capital cost recovery rules in recent years.
The Department of Finance estimates that the measure would expand immediate expensing from approximately 15% of business investment in capital assets under the Productivity Super Deduction to roughly two-thirds. That headline number is significant, but it is only part of the story.
The draft legislation contains several practical considerations that may matter more to businesses than the expansion itself, including which assets would qualify, how the proposed rules interact with the existing capital cost allowance (CCA) system, the impact on mergers and acquisitions (M&A) valuations, and whether a permanent immediate expensing regime should change how capital investments are evaluated.
Permanent Expansion of Eligible Property Is the Real Story
The PMD has largely been described as an expansion of the Productivity Super Deduction introduced in the 2025 federal budget. While that description is technically accurate, it understates the significance of the proposal.
The Productivity Super Deduction provided immediate expensing, meaning a full deduction from taxable income, for specified categories of property. The proposed PMD would make immediate expensing available on a much broader and permanent basis for qualifying depreciable property.
That is a meaningful change for capital planning. If enacted substantially as proposed, immediate expensing would become less of a temporary incentive to capture before an expiry date and more of a standing assumption in long-term investment models.
Exclusions Deserve Equal Attention
The government’s announcement focuses on expanded eligibility. However, the draft legislation shows that the boundaries of the regime will be just as important.
The proposed definition of “immediate expensing property” excludes several CCA categories, including property in specified portions of Classes 1 and 3; Classes 14, 14.1, and 51; and certain vehicles, qualified liquefaction equipment, and specified resource-related property.
Property that does not qualify for the PMD would generally remain subject to existing CCA rules, including the enhanced first-year deduction under the Accelerated Investment Incentive where applicable.
For businesses, determining whether a particular expenditure falls within the immediate expensing regime may become an important consideration in future investment decisions.
Asset Classification Becomes More Important, Particularly in M&A
One practical consequence of the proposal is that CCA classification may carry considerably more economic significance in business acquisitions.
Under the existing system, classification generally determines the rate at which the tax cost of an asset is recovered through deductions over time. Under the PMD, classification may determine whether the cost of an asset is recovered immediately or continues to be deducted over several years.
This change is particularly relevant in business acquisitions.
Consider an acquisition in which the purchase price is allocated among equipment, buildings, and goodwill. If the cost of qualifying equipment can be deducted immediately while goodwill and certain buildings remain outside the PMD, the allocation of consideration may have a significant effect on the purchaser’s tax profile.
For businesses negotiating asset acquisitions, tax analysis should be part of the transaction discussion before the purchase price allocation is finalized, rather than addressed after closing.
Important Rules Are in the Details
The draft legislation contains several important provisions that are easy to miss in a high-level review of the PMD.
First, the regime is not limited exclusively to new property. Subject to detailed eligibility and anti-churning rules, certain used property acquired on or after September 15, 2026, may qualify. At the same time, the rules are designed to prevent taxpayers from creating new immediate expensing opportunities through certain related-party transfers and other transactions.
One technical change that may receive less attention is the proposed definition of an “eligible partnership.” Under the proposed PMD, an eligible partnership must have members consisting entirely of corporations or other eligible partnerships. Partnerships with one or more individual partners would generally remain subject to the source income limitation.
Businesses operating through partnership structures, particularly corporate groups that use limited partnerships alongside corporations, should review how the proposed definition applies to their ownership arrangements before assuming the same treatment available under previous immediate expensing measures will continue.
The proposed rules also make clear that immediate expensing is not intended to create a second deduction under the CCA rules. Where a taxpayer claims the immediate expensing deduction for qualifying property, no other CCA deduction is available for that property for the year.
These provisions illustrate why the practical effect of the PMD will depend on the details of each transaction, not simply the 100% deduction headline.
Permanence Changes the Planning Question
The proposed permanent nature of the PMD may be as important as the expansion of eligible property.
Temporary incentives tend to influence the timing of capital expenditures. Businesses may move projects forward to take advantage of a higher first-year deduction before the measure expires or begins to phase out.
A permanent immediate expensing regime creates a different planning environment. Rather than asking whether an investment can be completed before a tax incentive expires, businesses can incorporate the proposed tax treatment into long-term capital budgeting, financing, and investment models.
That does not mean the tax deduction should drive an investment decision. The commercial return on the underlying project remains the starting point. The tax treatment may, however, change the after-tax economics of an investment that already makes sense from a business perspective.
For example, a manufacturer planning to acquire $5 million of qualifying equipment would generally recover its tax cost over several years under the existing CCA system. If the equipment qualifies for the PMD, the full $5 million could potentially be deducted in the year it becomes available for use.
The total tax deduction is not increased, but the timing of the deduction could materially improve near-term cash flow and reduce the amount of external financing required for the project.
Planning Should Begin Before Enactment
The PMD remains proposed legislation, and the final rules may change. That does not mean businesses should wait to assess the implications.
Companies with significant capital expenditures or acquisitions already in their planning pipeline should begin identifying which assets could qualify, which assets will likely remain subject to existing CCA rules, and whether transaction structures or purchase price allocations should be revisited.
The same analysis should be incorporated into capital budgeting models. The proposed regime could affect the timing of cash flows even if it does not change the total amount of deductions available over the life of an asset.
For businesses with large capital programs, the impact of deduction timing can be material.
Ryan Insight
The PMD will likely be remembered for expanding immediate expensing from a relatively targeted measure to a much broader part of the capital cost recovery system. For businesses, however, the more important change may be what that expansion does to the underlying tax analysis.
The distinction between qualifying and non-qualifying property becomes more significant. CCA classification matters more. Purchase price allocations may have a greater impact on cash taxes. The treatment of used property and related-party transactions requires closer attention. The permanent nature of the proposed regime also allows tax depreciation assumptions to be built into longer-term capital planning, rather than revisited every time a temporary incentive is introduced or approaches expiry.
Legislative proposals of this magnitude can create planning opportunities well before they become law.
Ryan can assist businesses in assessing how the proposed rules may apply to capital expenditure programs, potential acquisitions, and other transactions. This includes modelling the tax and cash flow impact of immediate expensing, reviewing CCA classifications and purchase price allocations, determining eligibility for immediate expensing, and assessing how the PMD interacts with existing CCA measures and other tax incentives.
