If you live in the Greater Toronto Area, you already know that long weekends and gas prices go together like traffic jams and the 401. Every holiday stretch brings the same question: Should you fill up now, or wait and hope for a dip?
This year, the stakes feel even higher. Global instability, refinery bottlenecks, and seasonal demand have all collided to create one of the most unpredictable fuel markets in recent memory. But thanks to updated forecasts from industry analysts and gas‑price tracking tools, we can make a well‑informed prediction about what GTA drivers will face at the pumps this long weekend.
Where Prices Stand Right Now
As of mid‑May 2026, GTA gas prices have been hovering in the 186–191¢/L range depending on the day and the station. CityNews reports that prices were expected to rise to 188.9¢/L on May 13, 2026, following a 2‑cent overnight increase.
Gas Wizard’s forecast for the same period shows regular gasoline at 190.9¢/L, up 3 cents from the previous day.
These numbers give us a baseline heading into the long weekend.
Short‑Term Forecast: A Drop Before the Weekend?
Here’s the good news: Industry analyst Dan McTeague predicts a price drop heading into the weekend.
FuelWise reports that GTA gas prices are expected to drop by 5¢/L on Thursday and another 7¢/L on Friday, bringing regular gasoline into the 185.9¢/L range.
If this forecast holds, drivers could see some of the lowest prices of the month just as the long weekend begins.
Why Prices Are Moving the Way They Are
To understand the weekend forecast, it helps to look at the forces shaping the market right now.
1. Global Oil Supply Disruptions
The ongoing conflict in Iran and the blockade of the Strait of Hormuz—through which 20% of the world’s oil normally flows—has created massive supply instability. This disruption pushed crude prices above $120 USD/barrel earlier this year.
Even though crude prices have eased slightly, the market remains volatile. Canada’s national average recently sat at 183.9¢/L, still far above last year’s levels.
2. Federal Excise Tax Suspension
The federal government’s temporary suspension of the fuel excise tax (10¢/L off gasoline) has helped soften the blow. Ontario’s provincial average sits around 169¢/L, though GTA prices tend to run higher.
This tax break remains in effect until September 7, 2026, meaning prices this weekend are lower than they otherwise would be.
3. Seasonal Demand and Summer Gasoline
Every spring, refineries switch to summer‑grade gasoline, which costs more to produce. Combined with increased travel demand and ongoing refinery maintenance, this seasonal shift pushes prices upward.
4. Ontario Refinery Bottlenecks
Ontario’s aging refinery infrastructure means even routine maintenance can cause sudden price spikes. Supply tightens quickly, and GTA stations adjust within hours.
So What Does This Mean for the Long Weekend?
Putting all the data together, here’s the most likely scenario:
1. Prices Will Dip Before the Weekend
FuelWise’s forecast of a 12‑cent total drop between Thursday and Friday is consistent with recent market behavior and analyst commentary.
If this holds, GTA drivers could see prices around 185–186¢/L heading into Saturday.
2. Prices May Rise Again During the Weekend
Historically, long weekends often bring a small bump at the pump due to increased demand. While no source explicitly forecasts a weekend spike, past patterns and current volatility make it a reasonable expectation.
3. The Window to Save Money Is Short
If you want the best price, Thursday evening or Friday morning is likely your sweet spot.
What Could Change the Forecast?
Even the best predictions come with caveats. Here are the biggest wildcards:
1. Geopolitical Escalation
Any new disruption in the Middle East—especially involving Iran or the Strait of Hormuz—could send crude prices soaring again. Analysts warn that the situation remains fragile.
2. Refinery Issues in Ontario
Unexpected maintenance or shutdowns at Sarnia or Nanticoke refineries can cause immediate price jumps. Ontario’s infrastructure is aging, and even minor issues ripple quickly through the GTA.
3. Market Reaction to Demand
If long‑weekend travel surges more than expected, stations may raise prices temporarily.
Tips for Saving Money at the Pump This Weekend
Here are some evidence‑based strategies drawn from analyst guidance:
- Fill up in the evening. Gas stations often raise prices during morning rush hours. FuelWise notes that evening fill‑ups (6–10 PM) can save up to 10¢/L.
- Avoid highway stations. They consistently charge more due to convenience pricing.
- Use price‑tracking apps. Tools like Gas Wizard and FuelWise provide real‑time updates and predictions.
- Top up before leaving the GTA. Cottage‑country stations often charge significantly more on long weekends.
Final Prediction: What You’ll Pay This Long Weekend
Based on the latest data:
- Thursday: ~186–191¢/L
- Friday: ~185–186¢/L (after predicted drop)
- Saturday–Monday: Likely 186–190¢/L, depending on demand and station behavior
If you want the lowest price, Thursday night or Friday morning is your best bet.
