How Shifting to E10 Could Reshape Fuel Pricing Across Canada
Governments are constantly looking for ways to lower the pump price for drivers while meeting climate targets. One emerging strategy—re‑baselining fuel price calculations on the lower‑cost ethanol‑blend E10—has already produced measurable savings in New Brunswick and Nova Scotia. This approach could become a template for provinces nationwide.
Why the E10 Blend Matters
E10 mixes 10 % ethanol with 90 % gasoline, reducing the overall cost of the fuel because ethanol can be produced locally from corn or wheat at a lower price than petroleum‑derived gasoline. According to the International Energy Agency, ethanol‑blended fuels cost on average 0.6 cents per litre less than pure gasoline in North America.
The Regulatory Lever: Adjusting the Petroleum Products Pricing Act
By redefining the “reference fuel” in the pricing formula, regulators can align the maximum price ceiling with the market‑available E10 blend. This method sidesteps the need for a separate carbon‑adjuster surcharge, which the New Brunswick Liberal government recently eliminated.
When the Energy and Utilities Board (EUB) adopts this change, the projected drop can reach up to 7 cents per litre—a modest yet tangible relief for commuters.
Real‑World Example: New Brunswick’s Quick‑Turn Policy Fix
In December 2023, a staff member reviewing the Petroleum Products Pricing Act identified the reference to “conventional gasoline” and proposed switching to E10. Ministers expedited the order, waiving the typical 28‑day public‑review period, and the adjustment was signed the same day. The outcome was an immediate, if temporary, price dip for drivers.
Similar steps were taken earlier in Nova Scotia, where the province reported a 0.5‑cent average reduction in the first month after adopting the E10‑based calculation.
What Consumers Can Expect Over the Next Five Years
- Gradual price stabilization: As more provinces adopt E10‑centric pricing, the market will likely see a smoother price curve rather than sharp spikes.
- Increased ethanol production: Farmers will diversify into ethanol feedstocks, boosting local economies and reducing reliance on imported crude.
- Potential for higher blends: With infrastructure upgrades, provinces might explore E15 or E20, further lowering carbon emissions and fuel costs.
Pro Tips for Drivers
- Check your station’s fuel type—E10 is often labeled as “regular” or “unleaded.”
- Use fuel‑price tracking apps to see if your area benefits from an E10‑based price cap.
- Consider flexible‑fuel vehicles that can run on higher ethanol blends without performance loss.
Frequently Asked Questions
- Is E10 compatible with all cars?
- Yes, most gasoline engines built after 2000 can run on E10 without modifications.
- Will switching to E10 affect fuel efficiency?
- E10 typically reduces fuel economy by 1–2 % due to ethanol’s lower energy density, but the cost savings often offset the slight drop.
- How does ethanol reduce the overall price of gasoline?
- Ethanol is generally cheaper to produce domestically, and its inclusion lowers the blended fuel’s wholesale cost, which cascades down to retail prices.
- What’s the difference between a carbon adjuster and a fuel surcharge?
- A carbon adjuster directly reflects federal clean‑fuel regulations in the price formula, while a fuel surcharge is a post‑hoc fee that stations pass on to customers to cover the same cost.
