On September 15, 2026, the Government of Canada proposed a new Productivity Mega Deduction, which would significantly expand the scope of capital investments eligible for Immediate Expensing.

If implemented as currently proposed, qualifying capital assets may be eligible for a 100% deduction of their capital cost in the year they become available for use, rather than being deducted gradually over multiple years under the traditional CCA (Capital Cost Allowance) system.

For Canadian businesses considering investments in equipment, computer software, production lines, transportation equipment, and other capital assets, this proposed measure is an important development to monitor.

  1. What Is the Productivity Mega Deduction?

When a Canadian business purchases a capital asset, the full purchase price is generally not treated as an immediate expense for tax purposes.

Instead, qualifying depreciable property is generally subject to the CCA system, under which the capital cost is deducted over time according to the applicable CCA Class.

Immediate Expensing changes the timing of that deduction.

Under Immediate Expensing, qualifying capital costs may be deducted in full in the year the asset becomes available for use, subject to the applicable rules and limitations.

For example:

A business purchases qualifying equipment with a capital cost of $1,000,000.

If the equipment qualifies for the Productivity Mega Deduction and becomes available for use during the year, the business may potentially deduct the full $1,000,000 capital cost in that year.

However, an important distinction should be made:

100% Immediate Expensing does not mean that the government is subsidizing 100% of the asset’s purchase price.

Rather, it accelerates the timing of the tax deduction. This can reduce taxable income in the current year and may improve the business’s cash flow and the after-tax economics of the investment.

  1. A Much Broader Range of Capital Investments May Qualify

The Productivity Mega Deduction builds on previous capital investment measures, including the Productivity Super-Deduction.

Under the existing Productivity Super-Deduction framework, certain qualifying investments benefit from immediate expensing, covering approximately 15% of capital asset investment.

The proposed Productivity Mega Deduction would expand the scope significantly. According to the Department of Finance, approximately two-thirds of capital asset investment could potentially qualify for Immediate Expensing.

The proposed measure would generally apply to most qualifying depreciable property acquired on or after September 15, 2026.

However, this does not mean that every asset purchased after that date automatically qualifies for a 100% deduction.

The asset’s CCA Class, acquisition date, whether it is new or used, when it becomes available for use, and how it is used by the business can all affect the tax treatment.

  1. An Important Number to Understand: What Does 6.4% Mean?

Another figure that has attracted attention is 6.4%.

It is important to clarify that:

6.4% is not Canada’s corporate income tax rate.

The figure refers to the Marginal Effective Tax Rate (METR).

METR is not a tax rate that businesses simply apply to their taxable income when filing a tax return. Instead, it is an economic measure used to assess the overall tax burden associated with an additional dollar of capital investment. It can take into account corporate income taxes, CCA deductions, investment tax credits, and other tax provisions.

According to the Department of Finance, previous capital cost measures had reduced Canada’s METR from 15.4% to approximately 13.0%. If the Productivity Mega Deduction is implemented as proposed, the government estimates that Canada’s METR could decline further to 6.4%.

Therefore, when discussing the 6.4% figure, it is important to distinguish between:

the corporate income tax rate

and

the Marginal Effective Tax Rate applicable to new capital investment.

These are two different concepts.

  1. How Much Tax Could a Business Save?

A simple example can help illustrate the potential cash-flow impact of Immediate Expensing.

Assume:

  • Qualifying equipment cost: $1,000,000
  • The equipment becomes available for use during the year
  • The business meets the requirements for Immediate Expensing
  • The business has sufficient taxable income to use the deduction
  • The applicable combined federal and provincial corporate income tax rate is assumed to be 26.5%

The theoretical current-year tax value of a $1,000,000 deduction would be approximately:

$1,000,000 × 26.5% = $265,000

However, this $265,000 should not simply be interpreted as a permanent $265,000 tax saving.

Without Immediate Expensing, the capital cost may also generate CCA deductions over future years.

The key benefit is therefore largely the acceleration of the tax deduction.

The actual economic benefit will depend on factors such as the company’s taxable income, future profitability, applicable tax rates, the asset’s CCA Class, and other tax considerations.

  1. Not All Assets Will Qualify for 100% Immediate Expensing

This is one of the most important points for businesses to understand when planning capital investments.

The proposed Productivity Mega Deduction does not cover every type of depreciable property.

According to the currently proposed rules, exclusions include certain:

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

For property that does not qualify for the Productivity Mega Deduction, existing measures such as the Accelerated Investment Incentive may continue to apply.

The proposed rules also contain additional restrictions for certain used property.

As a result, businesses should not assume:

“Any equipment purchased after September 15, 2026 can be fully deducted immediately.”

The actual treatment depends on the specific asset and the applicable tax rules.

  1. Why Does “Available for Use” Matter?

When planning capital investments, businesses often focus primarily on:

When was the purchase agreement signed?

When was the payment made?

However, for Immediate Expensing purposes, another important question is:

When did the asset become available for use?

Simply paying a deposit or signing a purchase agreement after September 15, 2026 does not automatically mean that the business can claim the full deduction in the 2026 tax year.

The applicable tax year may depend on when the asset was acquired and when it became available for use, together with the other requirements of the proposed rules.

For businesses planning equipment purchases, production line upgrades, technology investments, or other significant capital expenditures, the timing of the purchase, delivery, and availability for use may therefore have important tax implications.

  1. Greater Tax Certainty for Large Investments

In addition to the Productivity Mega Deduction, the Canada Revenue Agency (CRA) announced another measure related to major investments on September 14, 2026.

For investment projects involving $1 billion or more in Canada, the CRA will prioritize certain requests for an Advance Income Tax Ruling.

An Advance Income Tax Ruling can provide businesses with greater certainty regarding how the Canadian income tax rules will apply to a proposed transaction before it is implemented.

This can be particularly relevant for large-scale investments, complex corporate reorganizations, and significant cross-border transactions.

This measure is primarily aimed at major investment projects and does not mean that ordinary business purchases require an Advance Income Tax Ruling.

  1. What Does This Mean for Canadian Businesses?

If implemented as proposed, the Productivity Mega Deduction could significantly change the timing of tax deductions associated with capital investments.

For businesses considering equipment, computer software, production lines, transportation equipment, or other capital assets, it may be useful to review:

  1. Which CCA Class does the asset belong to?
  2. Is the asset eligible for the Productivity Mega Deduction?
  3. When is the asset acquired?
  4. When does it become available for use?
  5. Does the business have sufficient taxable income to use the deduction?
  6. If the asset does not qualify, how do existing Accelerated Investment Incentive rules apply?
  7. Are there additional considerations for used property, related-party transactions, or specialized assets?

These questions are often more important than simply asking whether an asset qualifies for “100% expensing.”

AYL CPA’s Perspective

For businesses planning significant capital investments, September 15, 2026 is an important date to keep in mind.

At the same time, the Productivity Mega Deduction is currently a proposed legislative measure. Its final scope, implementation rules, and detailed requirements will depend on the enacted legislation and subsequent guidance.

Businesses should therefore avoid making investment decisions based solely on the headline that qualifying assets may receive “100% Immediate Expensing.”

A more comprehensive approach is to consider the company’s profitability, cash flow, asset classification, CCA Class, acquisition date, available-for-use date, and overall tax position before deciding how and when to make a capital investment.

Tax planning is often not simply about calculating how much tax a business can save this year.

It is also about understanding:

When to invest, what to invest in, how the investment should be structured, and when the tax deduction will become available.

AYL CPA continues to monitor changes in Canadian tax legislation and helps businesses understand how new tax measures may affect their financial and tax planning. Our goal is to help businesses connect tax considerations with their broader financial and operational decisions.
