Canadian business news: Ontario says its new Ontario Competitiveness Tax Cut will hand businesses more than $8 billion in tax relief over five years, but the headline promise comes with a catch: it only takes effect once federal legislation passes.

Key Takeaways
- Ontario announced the Ontario Competitiveness Tax Cut on October 28, 2026, ahead of Finance Minister Peter Bethlenfalvy’s Fall Economic Statement on Thursday, October 29.
- The measure would provide more than $8 billion in additional provincial tax relief over five years.
- Eligible businesses could permanently and immediately write off 100% of the value of a wide range of capital investments.
- It only takes effect following passage of federal legislation. It is not yet claimable in full on that basis alone.
- The government projects at least $11 billion in additional capital investment, 30,000 new jobs, and about $6 billion added to Ontario’s GDP. Those are projections, not results.
What Ontario Announced
Ontario announced the Ontario Competitiveness Tax Cut on October 28, 2026, one day before the Fall Economic Statement. The measure is part of Ontario’s multi-year Tax Action Plan and is the provincial component of the federally announced Productivity Mega Deduction.
In plain terms, the province wants businesses to spend on equipment, buildings, and technology now, not years from now. Under the Ontario Competitiveness Tax Cut, eligible businesses would be able to permanently and immediately write off 100% of the value of a wide range of capital investments.
The list is broad. It includes fibre-optic cable, software, aircraft and certain vehicles, patents, rail track, machinery and equipment, bridges and roads. That range matters, because it reaches manufacturers, logistics firms, tech companies, and builders alike, not just one sector.
The Ontario Competitiveness Tax Cut in Numbers
The province puts the value of the measure at more than $8 billion in additional provincial tax relief over five years. Combined with accelerated write-off measures in Ontario’s 2026 Budget, total provincial tax relief supporting business investment would exceed $12 billion over five years.
Then come the projections, and they deserve to be labelled as exactly that. The government estimates the cut would drive at least $11 billion in additional capital investment, 30,000 new jobs, and about $6 billion added to Ontario’s GDP. None of that has happened yet. Those figures are what the government expects, not what it has delivered.
Ontario also cites a marginal effective tax rate on new investment falling to about 3.6%, versus 16.9% in the United States, 19% across the OECD, and 26% among G7 countries. Those comparisons are government figures, offered to make the case that Ontario would be the cheapest place in the G7 to invest.
Why Ontario Is Doing This Now
The timing is not accidental. The Ontario Competitiveness Tax Cut announcement is framed squarely as a response to United States tariffs, and to a fight for investment that Ontario believes it cannot afford to lose.
Finance Minister Peter Bethlenfalvy said: “In the face of U.S. tariffs, our government is helping Ontario businesses invest, grow and remain competitive on the global stage.”
He added: “The Ontario Competitiveness Tax Cut will be a gamechanger for business investment in the province, supporting 30,000 new jobs as we continue working to make Ontario the most competitive business environment in the G7.”
That is a bold claim, and it will be tested by something Ontario does not control: the federal Parliament. The cut only takes effect following passage of federal legislation, so businesses watching this announcement should read it as a plan in motion, not a tax break they can claim in full today.

Small Businesses Get a Separate Cut
The province also highlighted a previously announced small-business tax cut alongside the competitiveness measure. That cut benefits more than 375,000 small businesses, worth up to $5,000 per business per year, totalling $1.1 billion over three years.
That piece is separate from the Ontario Competitiveness Tax Cut, and it matters for a different reason: it reaches the small firms that will never buy an aircraft or lay rail track, but still feel every tariff and cost increase first.
What to Watch Next
- The Fall Economic Statement on Thursday, October 29, 2026, where Bethlenfalvy is expected to set out more detail.
- Progress of the federal legislation the Ontario measure depends on.
- Whether the Ontario Competitiveness Tax Cut prompts businesses to announce new investment, or they wait to see the final rules before spending.
- How the province measures the 30,000 projected jobs against real hiring in the years ahead.
With the Ontario Competitiveness Tax Cut, Ontario has made a big promise with a big number attached. The question now is whether the legislation, the investment, and the jobs follow in that order.
