Why it matters
- Canada proposes immediate expensing for about two-thirds of capital investment, up from roughly 15 per cent.
- The Department of Finance estimates a C$36 billion fiscal cost over five years and says the reform would cut the marginal effective tax rate on new investment to 6.4 per cent.
- A pro-investment tax reform should be permanent and neutral, but its cost and results need public measurement.
Canada has spent years asking businesses to invest while taxing investment as if delay were a civic virtue. Mark Carney’s government is now proposing a better rule. The Productivity Mega Deduction would make immediate expensing permanent for a much wider range of depreciable property acquired from September 15, covering about two-thirds of capital investment rather than roughly 15 per cent under the earlier measure.
The Department of Finance estimates an incremental fiscal cost of 36 billion Canadian dollars over five years. It says the reform would cut the marginal effective tax rate on new business investment from 13.0 per cent to 6.4 per cent, below the government’s stated 16.9 per cent US figure. Reuters reported the same scope and quoted BlackRock chief executive Larry Fink saying the proposed structure could bring more money into Canada if Ottawa follows through.
Immediate expensing is a useful reform because it stops the tax code from punishing a firm for buying a machine, software or fibre-optic cable today. The deduction changes the timing of tax, not the underlying economics of every project. A productive investment can start earning sooner; a weak project remains weak. That is a cleaner test than a minister choosing which industry deserves a bespoke grant.
The risk is fiscal optimism. Ottawa is asking businesses to believe that the extra investment will repay the cost through higher output, wages and tax receipts. That may happen, but a forecast is not a cheque. The government should publish the legislative text, a full list of exclusions and an annual scorecard showing private investment, productivity and the cost per dollar of additional capital formation.
Canada does not need another temporary programme that expires before a factory is designed. It needs a stable tax base that lets firms plan, build and compete. Permanent expensing is a move in that direction. Its credibility will depend on whether Ottawa treats the 36 billion dollar price tag as a commitment to measure results rather than an invitation to stop counting.
