The Fuel Excise Suspension Is Live: What It Means for Client Cash Flow and the April CPI Read

Two things happened in the same week. On April 20, Statistics Canada published March CPI data showing gasoline prices rose 21.2% in a single month, the largest monthly gasoline increase ever recorded in Canada. On the same day, the federal government’s temporary suspension of the 10-cent-per-litre federal fuel excise tax took effect. The timing is not coincidental, but the relief the suspension provides needs to be calibrated carefully against the scale of the shock it is responding to.

What the Excise Suspension Actually Does

The federal excise tax on gasoline is a flat levy of 10 cents per litre, applied at the point of production or import and embedded in the pump price consumers pay. Suspending it does not eliminate provincial fuel taxes, carbon pricing mechanisms that remain in place, or the retail margin that has also expanded during the crisis. In practical terms, a Canadian driver filling a 60-litre tank saves approximately $6.00 per fill at the pump, assuming the full benefit is passed through at retail. The Canadian Centre for Policy Alternatives and independent fuel pricing analysts have noted that pass-through is not always complete: refiners and retailers sometimes absorb a portion of tax changes rather than adjusting pump prices dollar-for-dollar.

The more significant effect may be on commercial operators. Trucking companies, agricultural operations, and construction firms that consume diesel in volume face meaningfully higher savings per fill than a passenger vehicle owner. A long-haul trucking operator running 500 litres per fill and filling twice a week saves approximately $1,000 per month per truck. At scale, this is material to operating margins that have been compressed significantly by the energy shock since March.

The CPI Picture and What Comes Next

March CPI came in at 2.4%, up sharply from 1.8% in February. The entire acceleration is attributable to energy: gasoline prices rose 21.2% in a single month, and fuel oil and other heating fuels rose 26.1% year-over-year. Excluding gasoline, CPI rose only 2.2%, which is essentially on target. This matters for the Bank of Canada because it signals that the energy shock has not yet meaningfully spread into core inflation. The Bank’s preferred measures, CPI-trim and CPI-median, were tracking at approximately 2.3% and have been easing in underlying trend terms since late 2025.

The problem is April. RBC Economics has estimated that headline CPI will exceed 3% in April, driven by continued elevated crude prices and the falling out of the carbon tax base-year effect, which had been suppressing the year-over-year comparison. The federal excise suspension, which took effect April 20, will offset some of this pressure in the April data, but not enough to prevent a headline reading that looks alarming in isolation. Statistics Canada will release April CPI on May 19. Between now and then, the Bank of Canada’s April 29 decision and Monetary Policy Report will be the most important data point for advisors to track.

What the April 29 Decision Means for Borrowing Costs

The overnight rate has been at 2.25% through four consecutive holds. Market pricing as of April 10 showed a 93% probability of another hold on April 29, with essentially no probability of a hike. The energy-driven inflation spike argues against cuts; soft growth and an unemployment rate holding at 6.7% argue against hikes. The Bank is effectively pinned. What makes April 29 different from a standard hold announcement is the accompanying Monetary Policy Report, which will publish the Bank’s updated forecasts for inflation, GDP, and employment with the full energy shock incorporated. Those forecasts will set expectations for the rest of 2026 and are the primary input for fixed-rate mortgage pricing in the weeks that follow. Clients with renewals approaching in the May to September window should be watching the MPR closely for signals on where the Bank sees the inflation path resolving.
