How Much Does Gas Fireplace Installation Cost in Toronto? (2026 Guide)

Here is the short answer for 2026: most complete gas fireplace installations in Toronto land between $4,500 and $10,000, including the fireplace, venting, gas line work and finishing. Converting an existing wood-burning fireplace with a gas insert typically runs $3,000 to $6,500 installed, and a gas log set can come in under $3,000. Where your project falls in those ranges comes down to four things, and this guide breaks down each one.

Toronto gas fireplace costs at a glance

The four parts of every installation quote

First, the fireplace itself, usually the biggest single line on the quote. Entry-level builder models start around $2,000 to $3,500, popular mid-range units run $3,500 to $5,500, and large linear designer fireplaces reach $5,500 to $10,000 and beyond.

Second, venting. A direct-vent fireplace needs a route to the outdoors, either straight through an exterior wall or up through the roof. A short horizontal run through the wall behind the fireplace is the simple case, typically at the low end of the $500 to $2,000 range. Long runs, offsets around framing, or roof terminations push toward the high end.

Third, the gas line. Expect roughly $500 to $1,500 depending on the distance from your meter or existing line to the fireplace location, and whether your current line has capacity for another appliance. This work must be done by licensed gas technicians and inspected.

Fourth, framing and finishing. A fireplace needs a wall to live in: framing, drywall or stone, a mantel or surround. Replacing an existing unit in the same opening keeps this near $1,000; building a new full-height stone feature wall from scratch can add $5,000 or more.

Insert, new install or log set: three different budgets

If you already have a wood-burning fireplace, a gas insert is usually the most economical route at $3,000 to $6,500 installed. The insert vents through a liner in your existing chimney, and the masonry opening replaces most of the framing and finishing work. Real gas heat, minimal construction.

A brand new direct-vent fireplace is the flexible option: it can go in almost any room, on an outside wall or with a vent run to the roof. That flexibility is what the $4,500 to $10,000 range pays for, since venting, gas line and finishing all scale with the location you choose.

A gas log set is the budget path for a working wood-burning fireplace in good condition: a realistic log and burner assembly installed in the existing firebox, typically $1,500 to $3,000 all in. It is more about ambience than heat output, and it keeps the fireplace you already have.

What moves the number up or down

Things that push a quote up: long or complicated vent routes, a gas line run across the house, high-end finishing like full-height stone, and condo installations that involve building management requirements. Things that keep a quote down: an exterior wall location, an existing gas line nearby, and simple finishing. None of this is obvious from a photo, which is why the ranges above are ranges, and why serious quotes follow a site visit or a detailed conversation about your space.

Permits, inspections and code in Ontario

Gas appliance work in Ontario must be performed by licensed gas technicians, and inspections are part of a professionally done installation. If your project involves structural changes, a building permit can apply as well. A reputable installer builds these requirements into the quote; a suspiciously low estimate that skips them usually costs more to fix later, and can void insurance coverage.

Why nobody serious quotes over the phone

A phone estimate for a fireplace installation is a guess about your venting, your gas line and your walls, made without seeing any of them. Anyone can pick a reassuring number that changes later. A written quote after reviewing your space is the number that actually holds, and it protects you as much as it protects the installer.
