On Sept 8, 2026, gas will jump ~10¢/L

The temporary suspension of the federal fuel excise tax ends. Here's the exact timeline, estimated impact, and strategy to minimize cost.

⏳ Countdown

On April 14, 2026, Prime Minister Mark Carney announced the temporary suspension of the federal fuel excise tax starting April 20, 2026. The measure ends on September 7, 2026 inclusive.

As of September 8, 2026, the tax returns to full force:

  • • Gasoline: +10 ¢/L
  • • Diesel: +4 ¢/L
  • • Aviation fuel: also restored

What this means for you

For an average Quebec vehicle consuming 1,750 L/year, that's about $175 more per year starting September 8, assuming everything else stays constant (which it won't — world oil price, USD/CAD, refiner margin also matter).

Cumulated over the 4 months remaining in 2026 (Sept-Dec), that's roughly $58 extra per average driver.

Suggested strategy for September 7, 2026

  1. 1.Do a full tank on Sept 5–6 and 7, ideally at your usual best station.
  2. 2.Do NOT stockpile gas in jerry cans: fire risk and evaporation losses wipe out the saving.
  3. 3.Beware anticipated hikes: some retailers may bump prices as early as Sept 6. Monitor provincial average via InfoGas.
  4. 4.Subscribe to price alerts on your usual stations (feature coming soon) to be notified of the first hike.

How to know if your retailer already restored the tax

InfoGas will show, starting September 1, an indicator on each station page: "Has this station already restored the full tax?". The calculation compares observed price against expected median (historical median + 10¢ post-Sept 8).
