A Decision Matrix and a Three-Winter Back-Test on Statistics Canada Price Data
Credit: Homeowner.ca
Every fall, oil- and propane-heated households get the same letter. Lock in now, cap your price for a fee, or ride the market. It reads like a pricing choice. It is actually a decision about risk: who carries the cost if the winter goes wrong, and what you give up if it goes right.
That decision matters most in Atlantic Canada, where oil is still the main heat source in more than a quarter of homes in Nova Scotia and Prince Edward Island. It also matters for rural propane households in Ontario and the West, whose contracts often come bundled with a rented tank and a minimum yearly purchase. Most of the guidance online is written for U.S. households, in gallons, under U.S. state rules.
This guide does two things. First, it lays out the four options side by side on the criteria that decide the outcome. Second, it tests each price structure against three real winters of Canadian heating oil prices, so you can see what locking in, capping or floating would have meant. No forecast. No supplier picks. Just the mechanics, the history and the clauses to check before you sign.
Start here. The table compares the three price structures suppliers offer, plus budget billing, which is often sold alongside them and often confused with them.
Canadian suppliers publish very few of their contract terms online. Treat the rows above as the questions to ask, then read your own agreement against them.
A pre-buy commits both sides. The New Hampshire Department of Energy describes it as a legally binding agreement under which the customer must purchase a set amount of fuel at a set price. That is the whole trade. You get a known price per litre. The supplier gets a known volume it can buy ahead.
The price is not today's price. One Ontario propane supplier states plainly that its pre-buy price is the current spot price plus a premium for storage and the market's expectation of future prices, and that the contract is irrevocable once accepted. Superior Propane says its fixed price is built from a 12-month outlook of supply, demand and inventories. Either way, you are paying for the supplier's view of the winter, plus a margin for carrying the risk.
The weak spot is volume. If you commit to 2,800 litres and burn 2,300, what happens to the other 500 depends entirely on your contract. The American guidance notes a typical approach is to apply the unused credit to off-season fuel at the current price, not the locked one. Some contracts carry it forward. Some do not. Ask before you sign, and get the answer in writing.
A capped plan sets a ceiling. When the market sits below it, you pay the market. When the market climbs above it, you pay the ceiling. You pay a fee for that protection whether or not the market ever reaches the cap.
That fee is rarely published in Canada. The only published range found in research for this guide comes from a U.S. market guide, which puts cap premiums at 10 to 30 cents per U.S. gallon, or roughly 2.6 to 7.9 cents per litre. Irving Energy's published U.S. terms show the other common features: the protection ends after a fixed period or when the covered volume runs out, and the plan requires automatic delivery.
A cap is useful when the fear is a spike, not a slow drift. It is least useful when the ceiling is set so high that the market never reaches it.
On a variable or market plan you pay the posted price on the day of each delivery. Nothing to break, nothing prepaid, and every movement in the market lands on your bill. Superior Propane notes that its variable propane rates typically rise in the fall and winter, which is exactly when a heating household buys most of its fuel.
Variable is not reckless. For a household that can absorb a bad month, or whose usage is too uncertain to commit to a volume, it avoids paying for protection it may not need.
This is the most common confusion in the category. An equal-payment plan spreads your estimated annual cost over 12 months. Ultramar, for example, re-evaluates the monthly amount every spring based on actual consumption and adjusts it.
Budget billing changes when you pay, not what you pay. Put it on top of a variable plan and a price spike still reaches you, just later, as a higher monthly amount or a balance at reconciliation. Put it on top of a pre-buy and you get both a known price and even payments.

If a sales pitch says a budget plan will "protect you from price increases," ask which price structure sits underneath it. The payment plan alone does not fix your price.
Statistics Canada's monthly retail price table publishes an average household heating fuel price, in cents per litre, for 16 Canadian cities, updated through August 2026. It has no propane series, so this test uses heating oil. Two cities were chosen: Halifax, because Nova Scotia does not regulate heating oil prices, and Montréal, as the central-Canada comparison.
The stylized household and contract terms are assumptions, stated in full so you can adjust them to your own situation:
Three seasons were tested: 2021-22, when prices climbed through the winter and spiked in spring 2022; 2022-23, when contracts were signed near the high and prices then eased; and 2024-25, a calmer year.
These figures are illustrative outputs of the assumptions above, calculated by Homeowner.ca from city-wide average prices. They are not what any supplier charged, not a forecast, and not a savings estimate for your home.
In a rising winter, locking in wins decisively. In 2021-22 the Halifax pre-buy came in about 21% below the variable total, and the Montréal pre-buy about 26% below. The cap captured roughly half of that benefit, because the ceiling was breached from January onward in Halifax and from October onward in Montréal.
In a winter that starts high, the lock can lose. Contracts signed in August 2022 locked in near the peak. When prices dropped through spring 2023, the pre-buy ended up slightly above the variable total in both cities. The cap roughly broke even: it held the November spike down, and the market price applied once it fell.
In a calm winter, the choice barely registers. In 2024-25 the three structures landed within about 4% of each other in both cities. The cap fee was the main difference, and it was only partly recovered in the two or three months the ceiling was reached.
The pattern is the point. A pre-buy is a bet that prices will rise from where you sign. A cap is a hedge against a spike, and it pays out only when one arrives. Variable accepts both outcomes. None of them is right every year, and the timing of your signature matters as much as the structure you choose.
One more reading of the data: prices have not been quiet in 2026. The Halifax average moved from 169.5 cents in February to 213.1 cents in April and stood at 210.2 cents in August. A contract signed this fall starts from an elevated base, which is exactly the setup that made 2022-23 a poor year to lock in and would have made 2021-22 a good one. Nobody knows which pattern this winter follows. For context on the wider price picture, see our coverage of the Bank of Canada's energy-price warning ahead of heating season.
Three Atlantic provinces set maximum prices for heating oil and propane. Nova Scotia does not.
In Prince Edward Island, the Island Regulatory and Appeals Commission sets only maximum prices for furnace oil and propane, not minimums. Furnace oil adjusts every Friday; propane every second Friday.
Newfoundland and Labrador's Board of Commissioners of Public Utilities sets maximum prices for furnace oil, stove oil and propane. Sellers may charge any price at or below the maximum, but never above it. Prices adjust weekly, with extraordinary adjustments possible.
New Brunswick's Energy and Utilities Board builds its weekly maximum from a seven-day average benchmark plus capped margins. The maximum retail margin is 27.21 cents per litre for furnace oil and 25.0 cents for propane, with a maximum delivery cost of 5.0 and 10.0 cents respectively.
In Nova Scotia, the regulator sets prices only for gasoline and diesel used in vehicles, so heating oil and propane prices are set by suppliers, according to the Atlantica Centre for Energy.
A regulated maximum is not a fixed price. It is rebuilt each week from the market benchmark, so when world prices spike, the ceiling rises with them. The regulation limits how much margin a supplier can add. It does not stop the price from climbing.
That makes a supplier cap less redundant than it first appears. In PEI, New Brunswick and Newfoundland and Labrador, a cap still protects against the benchmark moving up. What the regulation does is narrow the gap between the posted maximum and what a supplier can charge, which reduces the value of shopping around on variable price. A pre-buy or cap is worth comparing against the current regulated maximum on the day you sign: if the locked price is well above it, you are paying a lot for protection.
In a regulated province, ask whether your variable price is billed at the maximum or below it, and by how much. A standing discount below the ceiling is a real, comparable number.
This is the heart of the market. In 2023, oil was the primary heating energy for 28% of households in Nova Scotia and 28% in PEI, 13% in Newfoundland and Labrador and 3% in New Brunswick, according to Statistics Canada's heating survey. Those shares are falling fast: PEI was at 65% in 2013.
Tax is part of the comparison. PEI provides a point-of-sale rebate of the 9% provincial part of HST on qualifying heating oil, though propane does not qualify. Nova Scotia rebates the provincial portion of HST on home energy products, and if it was not deducted on your bill you can apply for it within 24 months. When comparing a locked price to a posted price, confirm both are quoted the same way on tax.

Oil heats about 2% of Quebec households. Prices are not set by a provincial ceiling, so the Montréal back-test above applies directly. Quebec's Bill 10 amendments to its Consumer Protection Act take effect September 12, 2026, with exceptions, and add clearer notices and easier cancellation for online subscriptions. Whether a particular fuel agreement falls under those new rules is a question to put to the Office de la protection du consommateur.
About 1% of Ontario households heat with oil and 4% with propane, mostly outside gas-served areas. Ontario's overhauled Consumer Protection Act, 2023 was not yet in force as of July 2026, so the existing rules still apply. Under them, a contract obtained through misrepresentation can be withdrawn from within one year, and door-to-door agreements carry a cooling-off period.
Many propane households in BC, Alberta and Saskatchewan rent their tank from the same company that sells them fuel. That link can matter more than the price plan. CBC reported in January 2025 that one national supplier raised annual tank rentals by 50% or more for some customers in Nova Scotia, New Brunswick, Newfoundland and BC, and that the contract required buying at least 200 litres a year or facing a standby fee whose amount the contract did not specify.
BC's amended consumer protection law, in force since August 1, 2026, requires businesses to give subscription customers notice 30 to 60 days before renewal and lets them cancel a renewal without penalty. If your propane agreement renews automatically, ask your supplier whether it treats the agreement as a subscription contract under those rules.

Use this list with your contract in front of you. Each question has a clear answer in a well-written agreement. If the answer is not in writing, ask for it in writing.
The tank question works much like the rent-or-own decision many Canadians face with water heaters; our water heater rental guide walks through the same trade-offs.
The back-test points to a simple rule: match the structure to what you can absorb, not to a guess about next winter.
Your usage is steady year to year and you can commit to a volume with confidence. A jump of a quarter or more in your heating bill would strain your budget. You accept that, in a year when prices fall, you will pay more than your neighbour on variable. And the contract handles unused litres in a way you can live with.
You want protection from a spike without giving up a drop. The ceiling sits close enough to today's price to matter, and the fee is modest relative to your annual bill. It also suits less predictable usage, provided the plan does not penalize you for using less.
You can absorb a bad winter, or you have money set aside for heating. Your usage is uncertain, perhaps because of a new home, a renovation or a planned switch to another heat source. Or you live in a regulated province and your supplier bills a known amount below the posted maximum.
Even monthly payments matter more to you than paying as you go. It layers onto any of the three price structures.
If you are weighing an exit from delivered fuel entirely, our heat pump rebate breakdown by province is the place to start.

No. A pre-buy fixes the price per litre for a set volume. A budget plan spreads your estimated annual cost into equal monthly payments. You can have either without the other, or both together.
It depends on the contract. Common approaches include a refund, a credit at the current market price, a carry-over to next season or a forfeit. Ask for the rule in writing before you sign.
Generally no. The fee pays for protection you had during the term, whether or not you used it. Confirm the terms with your supplier.
A regulated maximum in PEI, New Brunswick or Newfoundland and Labrador is recalculated weekly from market benchmarks, so it rises when the market rises. It limits supplier margins, not the direction of prices, so a cap can still provide protection.
Statistics Canada publishes monthly average household heating fuel prices for 16 cities. Natural Resources Canada links to weekly consumer propane prices for 29 cities and a Canada-wide average.
Rental agreements typically reserve filling to the tank's owner, which is why switching suppliers usually means swapping tanks. Check your agreement for removal fees and notice requirements before you switch.
Suppliers usually open fixed and capped offers in late summer and early fall, ahead of the heating season. Some programs run only from October to April, so check the start and end dates against when you actually take deliveries.
Many provinces give a cooling-off period for direct sales. Newfoundland and Labrador, for example, allows cancellation within 10 days of receiving the contract, without giving a reason, and requires a refund within 15 days.
Yes, but some provinces offset it. PEI rebates the provincial part of HST on qualifying heating oil at the point of sale, and Nova Scotia rebates the provincial portion on home energy products. Check how your contract price is quoted.
