Heating oil has become sharply more expensive heading into the 2026–27 heating season. In its Consumer Price Index release for September 2026, published October 19, Statistics Canada reported that prices for fuel oil and other fuels were 57.8% higher than a year earlier. The agency said the increase has a greater impact on consumers in Atlantic Canada, where oil remains a common home heating fuel.
What Statistics Canada reported
The short answer: energy drove the September inflation number, and fuel oil posted the steepest rise of the energy items named in the release.
Headline inflation reached 3.1% in September, up from 3.0% in August. Energy prices as a group rose 19.0% year over year, compared with 15.4% the month before. Statistics Canada linked part of the move to crude oil, which climbed in September to its highest level since May amid continued uncertainty about the wars in the Middle East.
The key energy figures in the release:
| Item | Year-over-year change, September 2026 | August 2026 |
|---|---|---|
| Energy (all) | +19.0% | +15.4% |
| Gasoline | +27.8% | +22.8% |
| Fuel oil and other fuels | +57.8% | +43.7% |
Excluding energy, prices rose 2.1%. Excluding gasoline alone, inflation was 2.2%.
How heating costs showed up in shelter
The short answer: the oil increase was large enough to lift the shelter index on its own.
Shelter prices rose 1.8% year over year in September, after 1.5% in August, and Statistics Canada named higher fuel oil and other fuel prices as a contributor to that acceleration. Two other shelter lines are relevant to anyone selling home services: homeowners' maintenance and repairs rose 1.2%, while homeowners' home and mortgage insurance rose 4.9%.
The regional picture
The short answer: Nova Scotia posted the highest provincial inflation rate in the release, and Atlantic provinces felt the oil increase most.
Among the provinces listed in the highlights, Nova Scotia's year-over-year rate was 3.3%. Prince Edward Island and New Brunswick were both at 2.6%, and Newfoundland and Labrador at 2.4%. Statistics Canada noted that five provinces saw faster price growth than in August, mainly because of gasoline and fuel oil.
Oil's share of home heating explains the regional difference. Statistics Canada's Households and the Environment Survey table for 2023 shows oil as the primary heating energy for 28% of households in Nova Scotia and 28% in Prince Edward Island, and 13% in Newfoundland and Labrador. In Alberta and Saskatchewan, by contrast, three in four households heat primarily with natural gas.
Analysis: what this means for heating contractors
This section is HeatingNews.ca analysis, not part of the Statistics Canada release.
A 57.8% index rise does not mean every oil customer's bill rose by that amount; delivery contracts, tank sizes and consumption vary. As a simple illustration of scale only: a household that spent $3,000 on heating oil over a past winter would be looking at roughly $4,700 if its price per litre tracked the index and its usage stayed the same. Numbers of that size change what an owner considers worth doing before January.
For contractors in the Maritimes and Newfoundland, three practical points follow:
- Expect more "should we switch?" calls. Homeowners compare the oil price they see this fall with a heat pump or electric quote. Have honest, current answers ready on running costs, and on which provincial programs are open. Our Nova Scotia, Prince Edward Island and Newfoundland and Labrador pages track what was open when we last checked.
- Service oil customers well, too. Many oil-heated homes will not switch this year. Tune-ups, efficiency checks and tank inspections are a natural fit for customers trying to stretch every litre.
- Keep price claims factual. If your marketing cites fuel costs, quote the source and date, as we do here. A sentence such as "oil prices are up 57.8%" without context invites complaints when a customer's own bill tells a different story.
Our fuel-switching campaigns page explains how we structure marketing for this exact situation, with messages that change when prices or programs do.
What to watch next
Statistics Canada publishes the October CPI in November. The detailed CPI tables also break out natural gas and electricity, which matter for contractors outside Atlantic Canada.

Frequently asked questions
How much did fuel oil prices rise in September 2026?
Statistics Canada's index for fuel oil and other fuels was 57.8% higher in September 2026 than in September 2025, according to the CPI release of October 19, 2026. In August the year-over-year rise was 43.7%.
Why does this matter more in Atlantic Canada?
Statistics Canada said the increase weighs more heavily on Atlantic consumers because fuel oil is more widely used there. Its household survey for 2023 shows oil as the primary heating energy for 28% of households in both Nova Scotia and Prince Edward Island.
Did the release give figures for natural gas or electricity?
The highlights we read did not give September figures for natural gas or electricity. Those series are published in Statistics Canada's detailed CPI tables.
Is this a forecast of this winter's heating bills?
No. The CPI measures price changes compared with a year earlier. It does not predict what a given household will pay this winter, which depends on delivery prices, consumption and weather.
