Canada’s latest tax reform package is aimed primarily at businesses, with the federal government introducing a Productivity Mega Deduction designed to make it easier for companies to write off major investments immediately.
The measure was announced on September 29, 2026, in Barrie, Ontario, as the government promoted a broader strategy to increase business investment, productivity and job creation across the country, including through its investment strategy.
Under the proposal, businesses would be able to deduct the full cost of a much wider range of eligible investments in the first year an asset becomes available for use, rather than claiming the cost gradually over several years.

What the new tax reform would change
The government says the Productivity Mega Deduction would expand immediate expensing from roughly 15 per cent of business assets to more than 65 per cent.
Potentially eligible investments listed by the government include fibre-optic cable, greenhouse structures, mining property, oil and gas pipelines, software, research and development, computer equipment, aircraft, vehicles, patents, rail track, bridges and roads.
Immediate expensing does not eliminate tax on business income.
Instead, it changes when a company can claim the cost of an eligible investment, reducing taxable income sooner and improving cash flow during the early years of a project.
For example, a company purchasing qualifying equipment could claim the full cost in the first year instead of spreading deductions over the asset’s depreciation period.
The precise treatment will depend on the final legislative and regulatory rules.
Why Ottawa is making the change
The federal government says the tax reform is intended to reduce the cost of investing in Canada and encourage companies to build, expand and adopt new technology domestically.
Finance Minister François-Philippe Champagne described the measure as one of the most significant changes to Canada’s business tax system in decades, while the government framed it as part of a plan to attract capital and support higher-paying employment.
The government estimates that the changes would lower the marginal effective tax rate on new business investment from about 13 per cent to 6.4 per cent.
That calculation concerns the tax burden on new investment rather than the personal income tax rate paid by employees.
It also does not mean that every business or every project would receive the same tax result.
Which businesses could benefit
The measure could be relevant to companies making large capital investments in sectors such as manufacturing, transportation, energy, mining, construction, agriculture, telecommunications and technology.
Businesses that purchase machinery, digital systems, vehicles, buildings or specialized infrastructure may see the greatest cash-flow benefit if those assets qualify under the final rules.
Smaller companies could also benefit, but the practical impact would depend on whether they have enough taxable income to use the deduction and whether their investments fall within the eligible categories.
Businesses that are not profitable may not receive an immediate cash refund simply because they make a qualifying investment.
They may instead carry losses or deductions forward, depending on the applicable tax rules.
How this fits with other 2026 tax measures
The business-focused announcement comes after several federal tax measures affecting households and homebuyers earlier in 2026.
The first federal personal income-tax rate was reduced to 14 per cent for 2026 and later tax years, a change discussed in a tax cut analysis and reflected in information about the new income-tax rate.
The federal government has also legislated a GST relief measure for eligible first-time buyers purchasing new homes, including a full rebate on qualifying new homes priced up to $1 million, as outlined in coverage of the GST cut for first-time buyers.
For individuals, the Canada Revenue Agency lists five federal tax brackets for 2026, beginning with a 14 per cent rate on taxable income up to $58,523 and rising to 33 per cent on taxable income above $258,482. The Canada Revenue Agency’s tax information provides the applicable rates and brackets.
The Productivity Mega Deduction is different because it is targeted at business investment rather than a broad reduction in personal tax rates.
What happens next
The announcement establishes the government’s policy direction, but businesses will need detailed legislation and administrative guidance before they can determine exactly which purchases qualify and when the measure takes effect. Canadians have also been invited to share their views on how tax dollars should be spent.
Key questions include the eligible asset classes, effective dates, interaction with existing capital cost allowance rules, treatment of projects already underway and any limits that may apply to related-party transactions or specific industries.
Companies considering major purchases should not assume that an announced deduction is available until the relevant legislation has been enacted and the Canada Revenue Agency has published the applicable guidance.
The government says the wider investment package, including public capital spending and incentives for third parties, is expected to support more than $1 trillion in total investment over five years, amid concerns about Canada’s debt and interest costs.
That projection depends on businesses and other investors responding to the new incentives and proceeding with projects in Canada.
For workers and households, the intended benefit is indirect, while Canada’s wealth gap remains a broader concern.
The government is betting that lower investment costs will lead to more construction, expanded production, stronger productivity and additional employment.
Whether those gains materialize will depend on business demand, interest rates, trade conditions and the final design of the tax rules.
