Canada’s Productivity Mega Deduction: What It Means for Business Aviation

September 15, 2026

On September 15, 2026, the Government of Canada, through the Department of Finance Canada, announced the proposed Productivity Mega Deduction, a major expansion of Canada’s capital cost allowance (“CCA”) regime intended to encourage business investment and strengthen Canada’s tax competitiveness.

The proposal would allow most depreciable capital property acquired on or after September 15, 2026 to be fully deducted in the year the property becomes available for use. For business aviation, this could substantially accelerate the tax deduction associated with qualifying aircraft and aviation equipment.

Although the Productivity Mega Deduction has not yet been enacted, it is expected to be implemented through forthcoming legislation and, given the government’s majority in the House of Commons, is widely anticipated to be enacted substantially as announced.

What Is the Productivity Mega Deduction?

Under the existing CCA system, taxpayers generally deduct the cost of depreciable capital property over time based on the prescribed rate for the applicable CCA class. The Productivity Mega Deduction would instead provide immediate expensing for most qualifying property.

The measure builds on the Productivity Super-Deduction announced in Budget 2025, which provided immediate expensing for approximately 15% of capital investment, including certain manufacturing and processing property, clean-energy equipment, zero-emission vehicles, patents, data network infrastructure and computers.

The new proposal is considerably broader. The Department of Finance estimates that approximately two-thirds of investment in capital assets would qualify for immediate expensing, at an incremental fiscal cost of $36 billion over five years beginning in 2026-27.

The government has proposed making the measure permanent as part of its broader objective of catalysing $1 trillion in additional investment in Canada. According to the Department of Finance, accelerated CCA measures announced in Budget 2025 reduced Canada’s marginal effective tax rate (“METR”) on new business investment from 15.4% to 13.0%. The Productivity Mega Deduction would reduce it further to 6.4%, compared with a 2026 U.S. METR of 16.9% and an OECD average of 19.0%.

YYZLaw’s Pre-Budget Submission

The announcement also follows recommendations YYZLaw submitted to the House of Commons Standing Committee on Finance in June 2026 as part of the Pre-Budget Consultations in Advance of the 2026 Federal Budget.

YYZLaw proposed a new Class 61 for “Designated Productivity-Enhancing Property,” with a 50% declining-balance base rate and enhanced first-year deductions of 100%, 75% or 55% for designated property. The proposal was intended to create a permanent framework for accelerating CCA treatment where investment would support Canadian productivity and competitiveness.

The Productivity Mega Deduction takes a broader approach. YYZLaw’s proposal contemplated designating specific categories of productivity-enhancing property for accelerated treatment, while the government’s proposal would extend immediate expensing to most depreciable capital property. Both approaches use accelerated CCA to encourage investment in Canada.

What Property Is Eligible?

The proposed rule is broad. Capital property subject to the CCA rules and acquired on or after September 15, 2026 would generally qualify unless it falls within one of the specified exclusions.

The principal exclusions are:

Class 1 and Class 3 buildings and additions to buildings;
Class 14 and Class 14.1 property, including franchises, licences and goodwill;
Class 51 property, including regulated natural gas distribution pipelines;
Certain vehicles in Classes 10 and 10.1; and
Property depreciated under Schedules V and VI of the Income Tax Regulations.

Manufacturing and processing buildings are excluded from the Mega Deduction because they fall within Class 1, but remain eligible for the separate temporary immediate-expensing treatment announced in Budget 2025. Property excluded from the Mega Deduction would continue to receive the existing temporary Accelerated Investment Incentive.

What Does This Mean for Aircraft?

Aircraft acquired after May 25, 1976 are generally included in CCA Class 9 and ordinarily carry a 25% CCA rate. Class 9 is not among the exclusions listed under the Productivity Mega Deduction.

Under the proposed rules, a qualifying aircraft acquired on or after September 15, 2026 can therefore qualify for immediate expensing in the year it becomes available for use.

Aircraft-related equipment may fall within different CCA classes and should be classified accordingly. Certain radar and radio equipment, for example, falls within Class 8, which is also not among the exclusions under the proposal.

The rules are also relevant to pre-owned aircraft. Previously used property can qualify where neither the taxpayer nor a non-arm’s-length person previously owned the property and the property was not transferred to the taxpayer on a tax-deferred rollover basis.

Existing CCA recapture rules also continue to apply. A larger deduction at acquisition may affect the tax consequences when the aircraft is later sold, making disposition planning an important part of the analysis.

Why It Matters for Business Aviation

The Productivity Mega Deduction follows another major federal tax change affecting aircraft transactions: the elimination of the luxury tax on subject aircraft effective November 5, 2025.

Together, these measures significantly improve the federal tax treatment of aircraft investment. The elimination of the luxury tax removed an additional acquisition cost from affected aircraft transactions, while the Productivity Mega Deduction would accelerate the deduction available on qualifying aircraft purchases.

For Canadian aviation businesses, this improves the economics of aircraft acquisition and fleet replacement and may encourage additional investment in aircraft, equipment, maintenance, refurbishment, management and related services.

The change is particularly relevant for businesses considering whether to acquire or replace an aircraft. The timing of the deduction can have a significant impact on cash flow and the after-tax economics of a transaction, especially where the aircraft represents a substantial capital investment.

What Aircraft Purchasers Should Know

September 15, 2026 is the key acquisition-date threshold under the proposed rules. The aircraft must also become available for use before the deduction can be claimed.

Purchasers should therefore consider closing and delivery dates, the available-for-use date, prior ownership, non-arm’s-length relationships and whether the transaction involves a tax-deferred rollover.

These issues will be particularly important where an aircraft is undergoing completion or refurbishment before entering service, where a transaction closes near a taxation year-end, or where related entities are involved.

The immediate deduction should also be considered alongside the potential tax consequences of a future sale, including the application of the existing CCA recapture rules.

Key Takeaway

The Productivity Mega Deduction represents a significant change in the tax treatment of capital investment in Canada. For business aviation, qualifying acquisitions of Class 9 aircraft made on or after September 15, 2026 can benefit from immediate expensing once the aircraft becomes available for use.

Combined with the elimination of the federal luxury tax on aircraft, the measure signals a clear shift toward encouraging aircraft and other productive capital investment in Canada.
