5 TSX Stocks Positioned to Gain From Ottawa's Productivity Mega Deduction

Canadian businesses can now immediately expense eligible capital assets acquired on or after September 15, 2026, with no per-taxpayer dollar limit. The write-off doesn't reduce total tax relief over the life of an asset, but it pulls that relief forward to year one, flooding the company with immediate cash flow. For capital-intensive TSX names already sitting on profits to offset, that's a direct funding source for major projects while interest rates remain in a lower range than the 2024 peak.

The immediate expensing measure, designed to close the "productivity gap" between Canadian firms and their U.S. counterparts, favors established companies with existing taxable income. A deduction is worthless to a startup with no profit. It's a windfall for a profitable incumbent that spends tens of millions on equipment, machinery, and software every quarter.

The telecommunications play

Rogers Communications (RCI.B.TO) and BCE Inc. (BCE.TO) qualify. Both are upgrading fiber networks and 5G hardware at a pace that outstrips depreciation schedules written for older technology. Rogers spent $3.7 billion on capital expenditures in 2025. The ability to write off the first $1.5 million of that spending immediately changes the quarterly CAPEX math: the tax savings reduce the net cash outlay in the same fiscal year, lowering the cost of borrowing for the rest.

Telecom firms operate under Class 44 and Class 50 CCA categories, exactly the asset types the immediate expensing rule targets. The equipment doesn't qualify under traditional building exclusions (Class 1 to 6), but switches, fiber, and software do. BCE's dividend stability depends on consistent spending on fiber, switches, and 5G equipment without ballooning debt service. Accelerated write-offs let the company fund upgrades from internal cash flow instead of drawing down credit facilities at the current overnight rate.

The energy angle

Enbridge Inc. (ENB.TO) runs pipelines that require continuous modernization. Compressor stations, monitoring software, and line integrity upgrades are all eligible under the mega deduction. Enbridge reported $6.7 billion in capital spending in 2025. The first $1.5 million written off immediately reduces taxable income in year one, freeing cash that would otherwise go to CRA in quarterly installments.

Pipeline operators face a timing problem: rate hikes increase debt costs faster than revenue can adjust, because pipeline tariffs are often set years in advance under regulatory contracts. The tax write-off doesn't solve the rate problem, but it does provide internal liquidity. That matters when a 1% increase in interest rates can outweigh the benefit of any single tax break. The accelerated deduction bridges the gap.

The utility defensive

Fortis Inc. (FTS.TO) operates regulated utilities across North America. Its capital spending is predictable and massive, averaging $4 billion annually on grid upgrades, renewable integration, and system hardening. Regulated utilities earn a fixed return on rate base, so the immediate deduction doesn't change the long-term earnings profile. What it does change is the cash conversion timeline. Fortis can deploy capital in Q1, write off $1.5 million, and reduce tax payable in the same fiscal year instead of waiting through a 10-year depreciation schedule.

David Rosenberg has emphasized defensive positioning in the Canadian market, focusing on quality balance sheets and dividend stability when the yield curve signals economic cooling. Fortis fits that profile. The company's payout ratio holds regardless of tax policy, but the accelerated write-off lets it maintain capital discipline without tapping external markets.

The industrials catch

Canadian National Railway (CNR.TO) is the wildcard. Rail operators spend heavily on track maintenance, rolling stock, and logistics software. CNI's annual capital budget runs north of $3 billion. The mega deduction applies to locomotives, signaling equipment, and automation tools, all of which fall under eligible CCA classes. The company's profitability is high enough that $1.5 million written off immediately makes a measurable dent in quarterly tax bills.

The caveat: accelerated deductions create a tax cliff in future years. CNI will have fewer deductions available in years three through ten, potentially leading to higher tax bills later. Companies that deployed capital aggressively during the peak incentive window between 2022 and 2024 are now seeing phase-outs begin. CNI's advantage is operational flexibility. The company can time major capital deployments to match the tax incentive cycle, something smaller operators can't do.

The write-off favors companies that already have the profits to shield and provides a funding bridge for the five above. It does nothing for growth names burning cash.
