Macklem Flags Energy-Price Spillover Risk With CPI Near 3%, Six Weeks Before Heating Season

If your home runs on natural gas — as most Canadian homes do — the Governor's warning is largely not about you, and it is worth saying so plainly rather than letting a headline do the work. Natural gas is priced through its own supply, storage and distribution system, and it is not a refinery product competing for distillate margin.

History supports the separation. Natural Resources Canada has reported that Canadian home heating oil prices in 2023 ran 40% to 70% higher than in 2020 depending on the jurisdiction, while residential natural gas costs rose 15% to 30% over the same period. Two fuels, one three-year window, materially different paths. That is a historical comparison rather than a 2026 forecast, and it does not mean gas is immune to global events. It does mean that treating every heating fuel as one exposed market is wrong.

The exposure is also concentrated in a way national averages hide. Roughly 25% of Atlantic Canadian households heat with oil, against about 6% across the rest of the country, and nearly two-thirds of those Atlantic oil-heated households sit at or below median income. Federal estimates put about 1.165 million Canadian homes on oil for at least part of their space heating as of 2020, including some 287,000 in the Atlantic provinces, 266,700 in Ontario and 465,200 in Quebec. Oil heating is a minority fuel nationally and a majority concern regionally.

Ontario households face a separate seasonal change on the same calendar, and it has nothing to do with refinery margins. The Ontario Energy Board resets Regulated Price Plan electricity prices once a year on November 1, and winter Time-of-Use periods and winter Tiered thresholds run from November 1 through April 30. For Tiered customers, the residential lower-price threshold rises from 600 kWh a month in summer to 1,000 kWh for the winter period — more consumption at the cheaper rate, which matters a great deal to an electrically heated home.

What is unusual this year is the information gap. The reset date is certain; the number is not yet public. As of September 2, 2026, the Board had not announced Regulated Price Plan prices for the period beginning November 1, 2026, and its most recent price announcement remains the one issued on Friday, October 17, 2025. That release set the winter Time-of-Use prices of 9.8, 15.7 and 20.3 cents per kilowatt hour and Tiered prices of 12.0 cents for the first 1,000 kWh per month and 14.2 cents above it — the rates Ontario households are paying right now, and only until October 31. Any electricity calculation you run this week uses a price with an expiry date on it. Note the announcement's precedent without treating it as a schedule: last year's came in mid-October.

Broader questions about where Ontario electricity prices go from here sit in a longer arc, which we covered in our look at Ottawa's clean electricity strategy and what doubling the grid by 2050 means for homeowners.

A fixed-price fuel contract is not a way to save money. It is a way to trade an unknown price for a known one, and whether that trade pays off depends entirely on what happens next — which nobody, including the Bank of Canada, claims to know. What the Governor's statement gives a homeowner is not a prediction. It is a documented, on-the-record reason to think the range of outcomes this winter is wider than usual, and that is the classic argument for buying certainty.

The Bank's accompanying press release put the same warning in its formal register, saying that "the longer that high oil prices and elevated refinery margins persist, the greater the risk of spillover to the prices of other goods and services", and scheduled the next rate announcement for October 28, 2026. That date sits three days before Ontario's rate reset and just ahead of the coldest part of the fall. Three decision points, one six-week window.

One caution about what follows. No Canadian regulator publishes standard terms for fixed-price, price-cap or pre-buy heating fuel contracts — those offers are commercial and vary by supplier — so the table below is a list of questions to ask, not a description of what is typical.

For the rate-path side of the same decision, our companion report covers the Bank's hold at 2.25% and its warning that consecutive hikes remain possible if oil keeps pushing inflation higher.

Servicing is the one item on this list that pays regardless of what fuel prices do. A furnace running at its rated efficiency burns less of whatever it burns, and a system that fails in January costs more than a system that fails in September. Natural Resources Canada advises that oil-fired furnaces and boilers need annual cleaning and tuning, while natural gas and propane furnaces and boilers should be serviced at least every two years.

There is also a supply-side reason to move early that has nothing to do with contractor schedules. Furnace oil inventories are built through the fall and drawn down through the coldest months, when demand runs at its seasonal peak and can exceed refinery production. That is a documented cycle, not a shortage claim. It simply means the fall is when the system has the most slack.

Worth being honest about the limits of that argument: no source establishes that service appointments become scarce in a particular week, and any supplier who tells you otherwise is selling urgency. Book early because it is easier, not because someone told you the calendar is closing.

If you ran heat-pump numbers last year and set them aside, the inputs have changed. Not the equipment, and not the rebates — the fuel price assumption underneath the payback period. Macklem said market expectations for oil have shifted up since July, and a payback calculation built on a lower expected fuel price now understates the case for switching.

The federal estimates give a sense of the stakes and of the spread. Natural Resources Canada has put heat pumps at two to four times the efficiency of an oil furnace, with an oil-heated household switching to an eligible unit saving roughly $1,500 to $4,500 a year, subject to regional and household factors. It has also estimated that a fully oil-heated Canadian home burning 1,000 to 3,500 litres a year spent roughly $2,000 to $5,500 on heating in 2023, depending on climate, province, equipment efficiency and heating load. Those ranges are wide for a reason. They are not your number.

So run your own. Pull your actual litres from last year's delivery invoices, use a current local quote rather than a national average, and if you are in Ontario, remember that the electricity side of the comparison changes on November 1. This is a calculation to revisit, not a purchase to rush — and the equipment decision has its own sequence of steps, which we set out in our guide to oil tank removal in Atlantic Canada and the conversion options that follow.

The Bank's position, stated plainly, is that the spillover has not happened yet. That is the sentence to hold onto. The reasonable response to a widened range of outcomes is to price your options while the market is calm and the calendar is open, and then to decide with real quotes in front of you.
