Convertissez votre fournaise au mazout au propane en Ontario<\/h1>

Planning to convert your oil furnace to propane in Ontario? TSSA permits, oil tank removal, costs, rebates, and the full conversion process explained.<\/p>

\"Oil<\/figure><\/header>

Converting from oil to propane is one of the most practical upgrades available to Ontario homeowners, especially in rural areas where natural gas service is nowhere on the horizon.<\/p>

Avenir Energy helps Ontario homeowners make the switch with full residential propane service: tank placement and setup on your property, automatic delivery scheduling so you never run low, and annual maintenance plans that include 24\/7 emergency support. If you’re ready to start the conversion, request a quote and our team will walk you through your options.<\/p>

This guide covers everything specific to Ontario: the TSSA licensing rules, the permit process, what happens to your oil tank, which rebate programs actually apply, and how to choose a propane supplier in your region.<\/p><\/section>

Why Ontario Homeowners Are Switching From Oil to Propane<\/h2>

Ontario’s rural heating market is dominated by oil and propane, because most homes outside major urban centres don’t have access to the natural gas distribution network. For decades, heating oil was the default. That’s changing.<\/p>

Heating oil prices are volatile and trending upward<\/p>

Heating oil is priced on the global crude oil market and denominated in US dollars. Every time oil spikes, Ontario homeowners feel it directly. Propane has a more stable domestic pricing structure in Canada and is produced in significant volumes within the country.<\/p>

Oil infrastructure has a finite lifespan<\/p>

Above-ground oil tanks typically last 20 to 30 years; buried tanks closer to 15 to 20 years. Most tanks installed in the 1990s and early 2000s are now at or past their service life. The liability for a leaking underground tank falls entirely on the homeowner, including soil contamination testing, Phase II environmental assessments, and any required remediation costs.<\/p>

Propane burns cleaner<\/p>

Propane produces roughly 12 to 15% fewer CO2 emissions per unit of energy than heating oil, based on Environment Canada emission factors. It contains no sulphur and leaves no residue in your combustion system, which means cleaner heat exchangers, fewer breakdowns, and longer equipment life.<\/p>

Your fuel supply is stored on your property<\/p>

Your propane tank sits on your property, so you’re not dependent on a utility pipeline or fuel delivery network to keep your supply available. A propane furnace does need electricity to run the blower and controls, but appliances like propane fireplaces can produce heat without any power at all.<\/p><\/section>

TSSA Licensing and Permits for Oil-to-Propane Conversions in Ontario<\/h2>

In Ontario, any work involving propane appliances, including converting from oil, must be done by a TSSA-licensed gas technician. The Technical Standards and Safety Authority (TSSA) regulates fuel safety in the province, and propane installations are governed under Ontario Regulation 211\/01 and CSA B149.1.<\/p>

Who Can Legally Do the Work<\/h3>

The technician handling your propane furnace installation and gas line connection must hold a valid TSSA Gas Technician (GT) certification. The TSSA registry lists registered contractors, not individual technicians \u2014 so ask the contractor directly to confirm which GT certifications their team holds:<\/p>

  • GT1 (Gas Technician 1): Can install, service, and repair propane furnaces of any BTU input in Ontario. Certified G1 technicians have the highest level of certification and are authorized by the Technical Standards and Safety Authority (TSSA) to work on both residential and industrial propane\/natural gas appliances.<\/li>
  • GT2 (Gas Technician 2): Qualified to install, service, and maintain propane furnaces and other propane-fired equipment with an input of up to 400,000 Btuh independently in Ontario.<\/li><\/ul>

    You can verify any contractor’s licence through the TSSA’s online licence registry before signing anything. Ask for the licence number directly and confirm it’s current. At Avenir Energy, we work with TSSA-licensed technicians and qualified installers who meet this requirement.<\/p>

    Licensing \u2014 No Separate Permits Required<\/h3>

    In Ontario, a residential propane furnace installation does not require a separate permit or gas installation permit. The work must be performed by a TSSA-registered contractor with appropriately certified gas technicians, and the contractor’s TSSA registration covers the regulatory framework for the job.<\/p><\/section>

    What Happens to Your Oil Tank in Ontario<\/h2>

    This is often the most complicated and consequential part of an oil-to-propane conversion in Ontario. Decommissioning an oil tank is a regulated process, and the liability for any contamination remains with the homeowner.<\/p>

    Above-Ground Oil Tanks<\/h3>

    Above-ground oil tanks (ASTs) in Ontario are regulated by the TSSA under O. Reg. 217\/01. Tanks used for heating fuel must be properly decommissioned by a qualified person. That process includes:<\/p>

    • Draining all remaining fuel (unused oil can be transferred to another tank or disposed of by a licensed waste carrier)<\/li>
    • Cleaning the interior to remove sludge and residue<\/li>
    • Rendering the tank incapable of holding fuel (removal, cutting, or approved slotting)<\/li>
    • Disposing of the tank through a licensed metal recycler<\/li><\/ul>

      Above-ground decommissioning typically costs $500 to $1,500 in Ontario.<\/p>

      Underground Oil Tanks<\/h3>

      Underground storage tanks carry a higher regulatory burden. If your home has a buried oil tank, common in homes built before the mid-1970s, you must:<\/p>

      • Hire a qualified environmental contractor to excavate and remove the tank<\/li>
      • Conduct soil sampling around the tank to test for petroleum hydrocarbon contamination<\/li>
      • If contamination is found, complete a Phase II Environmental Site Assessment (ESA) and remediate the soil to Ministry of the Environment standards<\/li><\/ul>

        Underground tank removal with clean soil test results typically costs $2,000 to $5,000. If contamination is present, remediation costs can reach $10,000 to $30,000 or more depending on the extent of the leak.<\/p>

        Do not leave a buried tank in the ground without formal assessment and documentation. If a tank leaks years after you assumed the issue was resolved, you or the next owner bears the full cleanup cost.<\/p>

        Paul M. Ladner, CEO of Avenir Energy, notes: “When you go from a 70% efficient oil furnace to a 96% propane unit, the fuel savings start compounding immediately. Add in the fact that propane produces no soot or residue in your heat exchanger, and you’re looking at lower maintenance costs and a furnace that lasts longer. That’s the real return on a conversion.”<\/p><\/blockquote><\/section>

        The Hybrid Heating Workaround<\/h2>

        If you install a hybrid heating system, pairing a propane furnace with an air-source heat pump, the heat pump component may qualify for rebates under Ontario’s Home Renovation Savings program and any active federal energy efficiency programs. In a hybrid setup, the heat pump handles the heating load down to approximately -15\u00b0C to -20\u00b0C, and the propane furnace takes over in extreme cold. This gives you rebate eligibility while retaining the cold-weather reliability propane provides in Ontario winters, and this setup is consistently one of the most efficient ways to heat in cold climates.<\/p>

        For the latest program details and eligibility requirements, speak with a licensed energy advisor who can complete a pre-retrofit EnerGuide assessment.<\/p>

        Pro Tip: If your home also has an aging oil or electric water heater, switching to a propane water heater at the same time as your furnace conversion can reduce installation costs through bundled labour. Ask your contractor to quote both together.<\/p><\/section>

        What an Oil-to-Propane Conversion Costs in Ontario<\/h2>
        Component<\/th>Typical Cost Range (Ontario)<\/th><\/tr><\/thead>
        High-efficiency propane furnace (supply + install)<\/td>$3,500 \u2013 $7,000<\/td><\/tr>
        Gas line installation (tank to furnace)<\/td>$500 \u2013 $2,000<\/td><\/tr>
        Propane tank setup (rental, often included with supplier agreement)<\/td>$0 \u2013 $500<\/td><\/tr>
        Oil furnace removal<\/td>$200 \u2013 $600<\/td><\/tr>
        Above-ground oil tank decommissioning<\/td>$500 \u2013 $1,500<\/td><\/tr>
        Underground oil tank removal (no contamination)<\/td>$2,000 \u2013 $5,000<\/td><\/tr>
        Total (above-ground tank, no contamination)<\/td>$5,000 \u2013 $12,000<\/td><\/tr><\/tbody><\/table><\/div>

        Most Ontario homeowners with above-ground tanks and no environmental complications land in the $6,000 to $9,000 range for a complete, permitted, inspected conversion. If you’re also replacing a water heater or adding a propane appliance at the same time, bundling the work with one contractor typically reduces overall labour cost.<\/p><\/section>

        The Conversion Process: Step by Step in Ontario<\/h2>
        • Get quotes from TSSA-licensed contractors. Confirm their licence number before signing anything.<\/li>
        • Choose a propane supplier and arrange tank placement. Your supplier will assess your property for tank location. For above-ground tanks, CSA B149.2 requires a minimum 3 metres (10 feet) from any building \u2014 setback requirements differ for underground tanks and smaller cylinders.<\/li>
        • Install the propane furnace. Avenir Energy\u2019s technician installs the furnace, runs the gas line from the propane tank, connects the appliance, and sets up the venting.<\/li>
        • Commission the system. Once the inspection is passed, the technician fires up the furnace, checks all connections under pressure, verifies thermostat operation, and walks you through the equipment before leaving.<\/li><\/ul><\/section>

          Choosing a Trusted Propane Supplier in Ontario<\/h2>

          Once your furnace is installed, you need a propane supplier to fill your tank. This decision matters more than most homeowners realize.<\/p>

          What to look for in a supplier:<\/p>

          • 24\/7 emergency service in applicable Ontario markets (critical in rural areas, where delays can leave you without heat for an extended period)<\/li>
          • Automatic delivery or remote tank monitoring so you never run out mid-winter<\/li>
          • Transparent pricing and clear delivery fee structure<\/li>
          • Residential heating experience, not just commercial cylinder service<\/li><\/ul>

            Avenir Energy serves residential propane customers across Southern Ontario, including areas formerly served by Sparlings Propane, one of Ontario’s longest-standing propane retailers. With our 24PROPLUS plan, you get priority emergency response, annual safety inspections, and proactive tank monitoring.<\/p>

            So when winter hits, you\u2019re not left wondering when your next delivery will arrive or who to call if something goes wrong. It\u2019s dependable propane support built for rural Ontario homes.<\/p><\/section>

              Frequently Asked Questions About Switching From Oil to Propane in Ontario<\/h2>
              Do I Need a Permit to Convert From Oil to Propane in Ontario?<\/summary>

              No. In Ontario, a residential oil-to-propane conversion does not require a separate building permit or gas installation permit. The work must be performed by a TSSA-registered contractor with certified gas technicians, and your propane supplier verifies the installation before the system goes live.<\/p><\/details>

              Can I Get a Rebate for Converting From Oil to Propane in Ontario?<\/summary>

              A straight oil-to-propane furnace conversion does not currently qualify for Ontario’s Home Renovation Savings program, as it focuses on heat pump adoption and building envelope improvements. The Canada Greener Homes Grant closed to new applications in February 2024. If you combine a propane furnace with an air-source heat pump in a hybrid configuration, the heat pump component may qualify for provincial rebates.<\/p><\/details>

              What Happens to My Oil Tank When I Switch to Propane?<\/summary>

              Underground tanks require excavation, removal, and soil sampling. If petroleum contamination is found, remediation under Ontario Ministry of the Environment standards is required. Never leave a buried tank in place without formal assessment and signed documentation from a qualified environmental contractor.<\/p><\/details>

              Is Propane Cheaper Than Heating Oil in Ontario?<\/summary>

              Fuel prices fluctuate for both, but the more meaningful comparison is cost per unit of usable heat. A modern high-efficiency propane furnace operates at 96 to 97% AFUE, converting nearly all fuel into heat. Most older oil furnaces run at 65 to 85% AFUE. That efficiency gap means propane delivers significantly more heat per dollar spent, even when the headline per-litre price looks similar to oil.<\/p><\/details>

              How Does Wireless Tank Monitoring Work With an Avenir Propane Account?<\/summary>

              With Avenir’s propane service, wireless tank monitoring comes built into your account \u2014 your supplier sees your levels in real time and schedules deliveries automatically. With oil, remote monitoring usually requires a separate aftermarket device, and you still manage ordering yourself.<\/p>

              A sensor on your propane tank transmits live level readings to our system around the clock. When your level drops to the reorder threshold, we schedule a delivery before you run out. You don’t need to track your usage or call ahead.<\/p>

              You can also check your level directly through your Avenir online account or the Nee-Vo app on your phone, which shows the same real-time data our delivery team is working from. For Ontario customers managing a rural property, a farm, or a seasonal home, this means your propane supply stays covered without you having to stay on top of it manually.<\/p><\/details>

              I’m Moving to a Rural Ontario Home With Oil Heat. Should I Convert to Propane?<\/summary>

              If the oil tank is aging or the furnace is more than 15 years old, converting before moving in is worth serious consideration. A pre-purchase home inspection that flags an aging oil tank or furnace is a legitimate negotiating point. You may be able to ask the seller to decommission the tank as a condition of sale, removing that liability before you take ownership. If you’re setting up propane service in Southern Ontario, we handle everything from tank placement to delivery scheduling and can connect you with a certified installer in your area.<\/p><\/details><\/section><\/article>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
