Ottawa Introduces the Productivity Mega Deduction: Permanent Immediate Expensing for Business Investment
The Department of Finance Canada has announced the Productivity Mega Deduction, a major new tax measure aimed at boosting business investment and strengthening Canada’s competitiveness among G7 nations. The measure allows businesses to immediately and permanently write off the cost of a broad range of capital investments in the year the asset becomes available for use — rather than depreciating it gradually over several years.
What’s Changing
This builds on the temporary Productivity Super-Deduction introduced in Budget 2025, which covered roughly 15% of capital investment — including manufacturing and processing equipment, clean energy assets, zero-emission vehicles, patents, data infrastructure, and computers.
The new Productivity Mega Deduction significantly expands this, making immediate expensing available on a permanent basis for approximately two-thirds of all capital asset investment in Canada.
Key effective date: Property acquired on or after September 15, 2026 is generally eligible.
What’s Eligible
Most depreciable capital property subject to CCA rules acquired on or after September 15, 2026 qualifies, except:
- Buildings and building additions (CCA Classes 1 and 3) — manufacturing/processing buildings remain covered under the temporary Budget 2025 measure instead
- Franchises, licences, and goodwill (Classes 14 and 14.1)
- Regulated natural gas distribution pipelines (Class 51)
- Certain vehicles (Classes 10 and 10.1)
- Property under Schedule V and VI of the Income Tax Regulations
Immediate expensing also extends to Canadian development expenses incurred on or after September 15, 2026.
Assets that don’t qualify continue to benefit from the existing Accelerated Investment Incentive first-year deduction.
Restrictions to Note
- Used property is only eligible if neither the taxpayer nor a non-arm’s-length party previously owned it, and it wasn’t acquired via a tax-deferred rollover.
- Loss-creation restrictions apply to individuals and partnerships with individual members, consistent with the 2021 small business immediate expensing rules.
Special Rules for LNG Facilities
Liquefaction equipment (Class 47) at LNG facilities receives an additional allowance bringing the CCA rate to 100%, but only against income from liquefaction activity at that facility. This measure applies to assets acquired on or after November 4, 2025, and LNG facilities are exempt from the emissions intensity requirement previously proposed for this benefit.
Why It Matters
According to Finance Canada, the measure is projected to:
- Reduce Canada’s Marginal Effective Tax Rate (METR) from 13.0% to 6.4% — well below the U.S. (16.9%) and OECD average (19.0%)
- Cost approximately $36 billion over five years, starting 2026‑27
- Generate economic output of up to $22 billion annually
- Support up to 80,000 additional jobs annually within ten years
The Bottom Line for Business Owners
If your business is planning capital investments — equipment, machinery, technology, or clean energy assets — timing those purchases around the September 15, 2026 threshold could have a meaningful impact on your tax position. Given the exclusions (particularly around buildings and used-property rules), it’s worth reviewing planned acquisitions with your advisor to confirm eligibility and optimize timing.
