A reference for the homeowner whose oil furnace is aging out or has failed and who is deciding what fuel runs the house for the next twenty years. The three real paths, what an oil-to-propane conversion actually involves, the rebate math written out plainly, and what the relationship with your propane supplier looks like after.
Stay on oil with new high-efficiency equipment, switch to propane, or move the house to an electric heat pump. Each path has a different equipment cost, a different rebate picture, and a different kind of home it fits. The page below walks through each one in order, in the homeowner’s vocabulary, with the rebate numbers source-attributed at the bottom of the section.
Replace the existing oil furnace with a new high-efficiency oil furnace. The fuel chain you already know, no tank conversion, no electrical work.
Decommission the oil tank, install a propane tank and high-efficiency propane equipment, switch the house onto a propane delivery schedule.
Move the house onto a cold-climate air-source or ground-source heat pump as the primary heating system. Backup electric resistance or a small backup fuel furnace, depending on the design.
A homeowner who has read the rebate stack on the heat-pump path and still wants propane is not making a mistake. There are specific situations propane fits better than electric heat — and a homeowner who knows which one is theirs is a homeowner who will be comfortable with the bill for the next twenty years.

No federal program currently pays a rebate on a high-efficiency propane furnace. The Canada Greener Homes Grant closed; the Canada Greener Homes Loan closed to new applicants in October 2025. The federal Oil to Heat Pump Affordability Program is still active in Ontario, delivered through IESO — but the program only funds switches from oil to an electric heat pump. A switch from oil to propane is excluded by design. The federal rebate stack on this path is $0.
Ontario’s Home Renovation Savings program is the province-wide rebate currently paying out. It funds heat pumps, heat-pump water heaters, insulation, windows, smart thermostats, and home energy assessments. A high-efficiency propane furnace is not an eligible measure. Replacing oil equipment with propane equipment captures $0 from HRS on the equipment itself.
HRS pays heat-pump rebates 2.5× larger to non-natural-gas-heated homes than to natural-gas homes — and a propane home is a non-gas home under the program. Installing a cold-climate air-source heat pump alongside the new propane furnace, with the heat pump carrying the shoulder seasons and propane covering the deep cold, captures $1,250 per ton up to $7,500 for a cold-climate ASHP. A ground-source heat pump captures $2,000 per ton up to $12,000. This is the largest single rebate available to a homeowner committed to propane as the primary winter fuel.
Insulation, windows, and air sealing through the HRS assessment-bundle stream cap at $10,000 for a non-gas home — most projects land somewhere below that. A heat-pump water heater paired with the conversion is another $500. A smart thermostat is $100. Bundling three or more assessment-stream upgrades adds a $500 bundle bonus, and the program reimburses up to $600 of the home energy assessment that anchors the bundle. None of this is for the propane furnace; all of it stacks alongside.
A homeowner converting oil to propane, installing a 3-ton cold-climate heat pump as a hybrid alongside the new propane furnace, and bundling envelope work (insulation, windows, air sealing) and a smart thermostat: heat-pump rebate $3,750 (HRS, propane home, $1,250/ton × 3), envelope bundle around $8,000 (under the $10,000 cap), smart thermostat $100, three-upgrade bundle bonus $500, home energy assessment reimbursement $600. Total realistic rebate stack ≈ $13,000 — and none of it is for the propane furnace. The propane furnace is paid out of pocket; the rest comes back through HRS. If the same homeowner is willing to drop the propane furnace and run an all-electric heat-pump path, the rebate stack on the equipment grows substantially under federal OHPA — the trade-off being that the house no longer keeps a fuel-based heat source for the deep cold.
The Guelph Greener Homes Program offers a 0%-interest 10-year property-tax-bill loan up to $50,000 for residential energy retrofits, with a separate $15,000 low-income grant stream for air-source heat pumps. The loan stream is currently waitlisted; the program does not fund propane or oil furnaces, but a hybrid heat pump installed alongside a new propane furnace is eligible for the heat-pump portion. Verify current waitlist status at the City of Guelph portal before relying on the program.
BetterHomes London is launching Spring 2026: a low-interest property-tax-bill loan up to $40,000 with a $10,000 income-based incentive on top, scoped to heat pumps and envelope work. Propane and oil furnaces are not eligible. Verify launch status and current terms at betterhomeslondon.ca before a London-region conversation that references the program.
Waterloo Region has endorsed the RetrofitWR program design but FCM funding has not yet been confirmed and there is no public launch date. The Region’s TransformWR climate plan targets a 100% reduction in fuel-oil and propane use by 2030, so eligibility is likely to follow the Guelph/London electrification scope when the program does launch.
A general Brantford energy-retrofit program is in design — expected 2026 rollout per City staff, terms not yet public. Separately, the income-restricted Ontario Renovates stream (sometimes informally called the Brantford Forgivable Loan) offers up to $25,000 fully forgivable over 10 years; for severely income-restricted Brantford-area households (~$33,500–$61,500 income, ~$30,000 asset cap), a furnace replacement — including propane or oil — may qualify when it is deemed an essential health-and-safety repair. This is the single program in B&J’s service area under which a propane furnace itself may be funded; the income bracket is narrow.
No municipal retrofit financing in these counties as of May 2026. Rebates flow through provincial HRS, and — for income-qualified oil-heated households — the IESO Energy Affordability Program with federal OHPA integration.
The house is on a different fuel, on a different schedule, with a different long-term relationship to its supplier. The four things that change in practice.
The article expands the page into a working reference: the eight-step project sequence with TSSA and CSA citations, the tank-ownership trade-off across fifteen years, the full rebate-stacking math, and a short section on what to ask an HVAC contractor before signing the conversion quote.
Assessment → permits → equipment selection → tank placement → line work → oil-tank decommissioning → commissioning → first fill. Every step with the responsible trade and the code or regulation that governs it.
Customer-owned versus supplier-owned, what each model does to the cost of ownership across a typical conversion lifecycle, and when each one is the right answer.
The setback table for aboveground tanks 125–500 USWG, 1,000 USWG and larger, underground tanks, and how the rules land on a rural lot, a small-town lot, and a tight urban infill.
What TSSA requires, what a qualified PM-2 contractor will do, and why the decommissioning record matters at the next property transaction.
The Perth County example from this page, expanded with line items for the heat-pump portion, the envelope bundle, the supporting measures, and the eligibility caveats.
The short list of questions a homeowner should put to the HVAC contractor before the conversion contract is signed — every one of them practical, every one of them grounded in the codes the work has to meet.
A named rep takes the call, not a queue. Tell us where the house is, what the oil furnace situation is, and where you are in the decision — staying on oil, converting to propane, or weighing the heat-pump path. We can usually settle the propane question and the next-step question in one conversation.
Standing routes across nine regions. Same rep year-round; off-hours emergency dispatch through the same number.
