Heating oil is up 44% from last year — how to budget for this winter's fill-ups

Headline inflation held at 3.0% in August. For homes heated with oil, the number that matters is much bigger. Statistics Canada's fuel oil and other fuels index rose 43.7% year over year in August, up from 29.5% in July. It's a big reason the Atlantic provinces had the highest inflation rates in the country.

The heating season hasn't started yet, so there's still time to plan for it.

What 44% looks like on your bill

Your own usage matters more than any average, so start from what you spent last winter:

• Spent $2,500 last season → roughly $3,600 at the same usage
• Spent $3,500 → roughly $5,000
• Spent $4,500 → roughly $6,450

Another way to see it: at 3,000 litres a year, a common figure for an older detached home in the Maritimes, every 10 cents per litre adds $300 to the season.

The CPI tracks prices, not bills. A mild winter or a better-sealed house can close some of the gap. A cold January can widen it.

Why there's no quick relief

• Crude is the driver. Oil has been above US$100 amid the Middle East conflict, and diesel and furnace oil come from the same refining stream. Heating-oil dealers in the Maritimes are warning that prices could climb further as demand picks up in the winter.
• The federal gas tax pause doesn't help. The excise-tax holiday extended to January 2027 applies to gasoline and diesel at the pump, not home heating oil.
• The carbon charge is already gone. The consumer fuel charge ended in April 2025, so no rebate or reduction is coming from that side either.

Help that opens October 1

• Nova Scotia's Heating Assistance Rebate Program (HARP) starts taking 2026–27 applications on October 1. Last season it paid $400 per household. It covers singles with net income up to $30,000, households up to $45,000, and anyone receiving GIS, the Allowance, or Income Assistance. About a third of last winter's budget went unused, so if you qualify, apply.
• Other provinces run their own winter programs, often opening in the fall. Check your provincial energy or social-services site before the first fill.
• The federal Oil to Heat Pump Affordability grant stopped taking new applications on July 31, 2026. If you already applied, final receipts are due by January 31, 2027. Make sure your installer is booked well before then.

If you're a senior on a low income, a GIS top-up is what qualifies you for HARP. Use the GIS calculator to check whether you're eligible.

Four ways to spread out the cost

1. Ask your dealer about a budget or equal-billing plan. Spreading the year's estimated cost over 10 or 12 months doesn't cut the price, but it takes the shock out of a $1,000 January fill.
2. Compare fixed-price or capped contracts carefully. Locking in a price protects you if prices keep rising. It costs you if prices fall. With prices this unpredictable, neither outcome is guaranteed.
3. Get the furnace serviced now. A tune-up and a clean nozzle are cheap compared with burning extra oil all winter.
4. Seal the cheap stuff first. Weather-stripping, a programmable thermostat and closing off unused rooms often pay for themselves within a single season at these prices.

Build it into the monthly budget

Take your estimated seasonal increase, divide it by the months left until spring, and set that amount aside every month starting now. For a home going from $3,500 to $5,000, that's about $250 a month from October through March. Compare that with what the average household in your province spends on shelter using the cost of living tool.

The takeaway

Heating oil is the fastest-rising item in the CPI right now, and it's concentrated in the regions that can least avoid it. Estimate your season from last year's bills, apply for provincial help as soon as it opens October 1, and set up equal billing before the first cold snap so the extra cost doesn't all land in one month.
