If you still heat your Ottawa home with oil, you are in a shrinking minority — and paying for it. Oil heating costs 30–60% more per year than natural gas, oil furnaces have fewer high-efficiency options, and finding HVAC technicians who service oil equipment is becoming increasingly difficult. On top of that, oil to gas conversion is now one of the most heavily subsidized home upgrades in Canada, with federal and provincial programs specifically designed to help homeowners like you make the switch.
This guide walks Ottawa homeowners through the entire oil to gas conversion process — from first assessment to final inspection. Whether you live in Kanata, Barrhaven, Orleans, or the rural outskirts of Ottawa, this guide covers what to expect, what it costs, and how to maximize your rebates.
Why Ottawa Homeowners Are Switching from Oil to Natural Gas
The benefits of an oil to gas conversion go well beyond fuel savings. Here is what Ottawa homeowners gain from making the switch:
💰
30–60% Lower Fuel Costs
Natural gas is significantly cheaper per unit of heat than heating oil. An Ottawa home spending $3,000–$4,000/year on oil typically drops to $1,500–$2,000 on gas.
📈
Higher Home Resale Value
Homes with natural gas heating sell faster and command higher prices in the Ottawa real estate market. Oil heating is seen as a liability by most buyers.
🌱
Cleaner & More Efficient
Natural gas burns 30% cleaner than heating oil. New 96% AFUE gas furnaces convert nearly all fuel to heat — oil furnaces max out at 86% AFUE.
🚫
No More Oil Tanks or Deliveries
Eliminate oil tank leak risks, soil contamination liability, and the hassle of scheduling oil deliveries. Natural gas arrives through underground pipes — no running out mid-storm.

The Oil to Gas Conversion Process: Step by Step
Here is exactly what happens during a complete oil to gas conversion Ottawa project from start to finish:
Step 1 — Week 1
Free Home Assessment & Quote
A Gas Man Ottawa technician visits your home to evaluate your current oil heating system, inspect ductwork, check gas line availability, and assess the oil tank situation (indoor vs buried). You receive a detailed quote covering every component of the conversion.
Step 2 — Week 1–2
EnerGuide Pre-Retrofit Audit (for rebates)
If you plan to claim Canada Greener Homes grants, a certified energy advisor performs a home energy audit before any work begins. This establishes your baseline energy performance and is required for rebate eligibility.
Step 3 — Week 2–4
Enbridge Gas Line Connection
If your home does not currently have a gas line, Enbridge coordinates the connection from the street main to your gas meter. In many Ottawa neighbourhoods this is subsidized or free. The timeline depends on Enbridge’s schedule — plan 2–6 weeks.
Step 4 — Day 1 of Installation
Oil Furnace Removal & Oil Tank Decommissioning
The old oil furnace is disconnected and removed. Indoor oil tanks are drained and removed for proper disposal. Buried tanks require excavation and soil testing — if contamination is found, remediation adds time and cost. The oil supply lines are capped and removed.
Step 5 — Day 1–2
Gas Piping & New Furnace Installation
Interior gas piping is run from the meter to the furnace location. The new gas furnace is installed, PVC venting is routed through the sidewall, and the condensate drain is configured. If you are also adding a heat pump or upgrading to a smart thermostat, these are installed simultaneously.
Step 6 — Day 2
Testing, Inspection & Commissioning
The system is fully tested — gas leak check, combustion analysis, airflow verification, and safety system testing. A TSSA inspection confirms code compliance. You receive a walk-through of your new system.
Step 7 — After Installation
EnerGuide Post-Retrofit Audit & Rebate Submission
The energy advisor returns for the post-installation audit to measure your improved efficiency. This documentation is submitted to the Greener Homes program to trigger your rebate payment. Gas Man Ottawa assists with all paperwork.

What Should Replace Your Oil System? Furnace vs Boiler vs Heat Pump
The best replacement depends on what type of oil system you currently have and your home’s distribution method:
If you have an oil furnace with ductwork → A high-efficiency gas furnace (96% AFUE two-stage) is the most straightforward swap. Existing ductwork is reused. Add a heat pump for dual-fuel operation and maximum rebates.
If you have an oil boiler with radiators → A gas boiler replaces the oil boiler and uses your existing hydronic piping and radiators. No ductwork changes needed.
If you want to go all-electric → A cold climate heat pump can fully replace oil heating, but Ottawa’s extreme winters usually warrant keeping a gas furnace backup. See our heat pump vs furnace comparison for details.
If you have no ductwork → A ductless mini-split heat pump provides zoned heating and cooling without the cost of adding ductwork. Pair with a gas boiler for backup.
Oil Tank Removal: What Ottawa Homeowners Need to Know
The oil tank is often the most unpredictable cost variable in a conversion project. Here is what to expect:
Indoor above-ground tanks ($500–$800 removal): The simplest scenario. The tank is drained, disconnected, removed, and disposed of according to Ontario regulations. Any remaining oil is pumped out and recycled.
Buried underground tanks ($1,000–$3,000+ removal): These require excavation. If the tank has leaked, soil testing is mandatory and remediation costs can add $3,000–$15,000+ depending on the severity and proximity to groundwater. In Ottawa, the TSSA and Ontario Ministry of Environment regulate underground tank removal.
Liability note: As the property owner, you are legally responsible for any environmental contamination from your oil tank — even if it was installed by a previous owner. This is one of the strongest arguments for converting sooner rather than later, especially if you have a buried tank older than 15 years.

Frequently Asked Questions About Oil to Gas Conversion in Ottawa
How much does an oil to gas conversion cost in Ottawa?
The total cost ranges from $4,500 to $10,000 before rebates. The main variables are whether you need a new gas line from the street (which Enbridge often subsidizes) and whether you have a buried oil tank requiring excavation. After rebates, most Ottawa homeowners pay $2,000–$5,000 net.
How long does an oil to gas conversion take?
The on-site installation work takes 2 to 4 days. However, the full project timeline — including the EnerGuide audit, Enbridge gas line connection, and scheduling — typically spans 4 to 8 weeks from start to finish. Planning in spring or summer avoids heating season disruptions.
How much will I save on heating by switching from oil to gas?
Most Ottawa homeowners save 30–60% on annual heating costs. A home spending $3,000–$4,000 per year on oil typically drops to $1,500–$2,000 with a high-efficiency gas furnace. Combined with rebates, the conversion often pays for itself in 3–5 years through fuel savings alone.
Is natural gas available in my Ottawa neighbourhood?
Most urban and suburban Ottawa neighbourhoods have Enbridge gas service. Some rural areas south and west of Ottawa may not have gas mains. Contact Enbridge directly or ask Gas Man Ottawa during your free assessment — we can quickly verify gas availability at your address.
What happens to my old oil tank?
Indoor tanks are drained, removed, and disposed of through licensed waste contractors. Buried underground tanks are excavated and removed, with soil samples taken to test for contamination. If your buried tank has leaked, soil remediation is required by Ontario environmental regulations. Your Gas Man Ottawa assessment includes an evaluation of your oil tank situation.
Can I keep my existing ductwork or radiators?
Yes in most cases. If you have a forced-air oil furnace with ductwork, the ductwork is reused for the new gas furnace. If you have an oil boiler with radiators, the radiators and piping are reused with a new gas boiler. Ductwork may need repairs or sealing if it is in poor condition.
Should I add a heat pump during my oil to gas conversion?
It is an excellent time to consider it. Adding a heat pump during the conversion maximizes your rebate eligibility (heat pump rebates are the highest available) and gives you a dual-fuel system that minimizes gas use. The heat pump handles heating in mild weather and all your cooling, while the gas furnace covers extreme cold.
Does Enbridge charge for the gas line connection?
Enbridge often provides free or subsidized gas line connections for new residential customers, especially in established neighbourhoods. If your home is far from the gas main, there may be a charge. The cost and eligibility depend on distance and infrastructure — Gas Man Ottawa helps you navigate this during the assessment.
Is oil to gas conversion worth it if I plan to sell my home?
Absolutely. Oil heating is a red flag for Ottawa home buyers — it signals higher running costs and potential oil tank liability. Converting to gas removes this concern, often increasing your home’s market value by more than the conversion cost. Real estate agents in Ottawa consistently cite oil heating as a top negotiation point that reduces offers.
Will I lose heat during the conversion?
The installation itself takes 1–2 days during which your heating system will be offline. This is why spring and summer are the preferred seasons for conversions. If the work must happen in winter, Gas Man Ottawa can coordinate the schedule to minimize downtime — typically completing the swap within one full day so your home has heat by evening.
