What does gas fireplace installation in Toronto include?
Best HVAC Toronto is a family-owned, TSSA-certified HVAC contractor serving Toronto and the GTA, with over 20 years of combined Ontario HVAC crew experience and manufacturer-authorized dealer status with Napoleon. Best HVAC Toronto installs natural gas fireplaces from downtown Toronto to Vaughan, handling new full-unit installations, direct-vent inserts into existing masonry or factory-built fireplaces, and wood-to-gas conversions. Every installation is performed by our TSSA G2 certified team, quoted in writing before any work begins, and completed with the required building permit and a TSSA pressure test.
Gas fireplace installation is licensed gas work in Ontario. The technician connecting your appliance to the gas supply must hold a current TSSA G2 certification. Every Best HVAC Toronto gas technician carries that certification and works under WSIB coverage and $2M general liability insurance, which means the paperwork is correct, the pressure test is performed and tagged, and you are not left with uninspected work that causes problems at home sale or insurance claim time.
The choice of venting type is the first decision every installation depends on. Direct-vent units draw combustion air from outside through a sealed co-axial pipe and exhaust flue gases back out through the same assembly, making direct vent the safest and most versatile option for nearly any room in a Toronto home. B-vent units draw room air and vent upward through the chimney, requiring vertical clearance and an appropriate flue. Ventless units burn without external venting and rely on oxygen-depletion sensors, but the Ontario Building Code restricts where they can be placed. We assess your room, ceiling height, exterior wall access, and gas line proximity before recommending a type, rather than defaulting to whatever is easiest to install.

Which gas fireplace or insert is right for your room?
Direct-vent inserts into existing fireplaces
The most popular request we receive from homeowners with an unused or drafty wood fireplace. A direct-vent insert slides into the existing firebox opening behind the original mantel and hearth, connects to a co-axial liner running up the chimney or through a side wall, and converts the space into a functional, safe gas appliance without major renovation. Starting from $2,500, it is the fastest and most affordable path to a gas fireplace in an older Toronto or North York home.
New built-in gas fireplaces from Napoleon and other leading brands
For rooms without an existing fireplace, a full standalone gas fireplace unit is framed into the wall with a new venting run to the exterior, then finished with a mantel, stone or tile surround, and glass front. Direct vent is the preferred option where an exterior wall is accessible, and linear models suit modern condo townhouses and renovated basements. Our team designs the venting route during the site visit so there are no surprises about penetration locations or finishing requirements.
Wood-to-gas conversions
An existing masonry or factory-built wood fireplace can be converted to gas using an insert and a correctly sized liner. We assess the existing chimney and flue, confirm it is structurally sound, and size the liner to the insert’s venting requirements. The result is a gas appliance using the existing firebox structure, which saves construction cost compared to a full new installation.
What happens after the fireplace is installed?
Proper commissioning is the step most often skipped by contractors who are unfamiliar with gas appliance work. After the unit is installed and vented, the Best HVAC Toronto crew pressure-tests the gas supply line, confirms the venting is drawing correctly, measures carbon monoxide at the room level, and runs the fireplace through its operating range on the remote or wall thermostat before signing off.
The carbon monoxide check is not optional. Ontario’s Fire Code requires a functioning CO detector on the same floor as any gas-burning appliance. We confirm the existing detector is within its service life and correctly placed, and we advise on upgrading to a combination smoke and CO detector where needed. This step takes ten minutes and it is the one that matters most for the safety of your household.
After the first season, book annual gas fireplace maintenance to clean the burner and pilot assembly, inspect the glass gasket, and recheck venting. We also handle gas fireplace repair on existing units, from a pilot light that will not stay lit to a fireplace shut off by an Enbridge Red Tag.
Fireplace projects from Etobicoke bungalows to Vaughan custom homes
We install gas fireplaces in homes across Toronto, including older Edwardian semis in Leslieville and the Danforth and post-war bungalows in East York, York, and Etobicoke with existing masonry fireplaces that suit a direct-vent insert, and in newer detached homes and townhouses in North York, Scarborough, and the GTA suburbs where a full framed-in unit is the right approach. Custom homes in Vaughan, Richmond Hill, and Markham often have two or three fireplaces that need coordinated gas line sizing so no single appliance starves the others.
The diversity of housing stock across the GTA means venting solutions vary considerably from job to job. An Etobicoke bungalow with a brick chimney and a clear exterior wall is a different project from a downtown Toronto semi where an adjacent shared wall limits penetration options. We plan the route during the site visit, file the City of Toronto or local municipal building permit, and price the job in writing, so you know what is happening and where before we start.
