Instant heat, already plumbed to your street through Enbridge Gas.

Typical installs run $6,000 to $15,000 CAD. A direct-vent insert dropping into an existing masonry firebox in an older Riverdale or Leslieville home, with a gas line already nearby, tends toward the lower end. A new built-in unit for a condo renovation or a fresh addition—where venting has to be run through a wall or up through multiple floors—pushes toward the top of that range, especially in high-rise buildings where the strata or condo corporation has specific rules about penetrating the exterior envelope.

Yes, and it is a common request in Toronto's older housing stock, where masonry fireplaces were often built decades ago to burn sugar maple or red oak. A gas insert typically slides into that existing firebox with a stainless liner run up the old chimney, which usually lands in the $6,000-$9,500 range. If the wood fireplace never had a WETT inspection or the chimney needs relining anyway, converting to gas sidesteps the ongoing insurance requirement that applies to solid-fuel appliances and modernizes the fireplace in the same project.

Enbridge Gas serves nearly all of the city, so most homes—whether a semi in Scarborough or a townhouse near the waterfront—already have a line for the furnace or water heater that a fireplace can tie into. The exceptions tend to be very new developments where gas metering is still being extended, or condo towers where gas is centrally managed and individual units may not have direct access. A local dealer can confirm what is actually feeding your specific address before you settle on a model.

Most will, and that matters in a city that has seen multi-day outages during ice storms, including the widespread one in December 2013. Units with intermittent pilot ignition run on battery backup that kicks in automatically when Hydro One, Toronto Hydro, or Alectra Utilities service drops. Some standing-pilot models skip batteries entirely since the thermocouple generates its own current. If outage resilience matters to you, ask your dealer which ignition system a given model uses before you commit.

A gas fireplace is a built-in unit framed into a wall, common in new construction or a full renovation. A gas insert fits inside an existing masonry firebox, which is the typical retrofit in Toronto's older neighbourhoods where a fireplace originally burned maple or oak. A gas stove is freestanding on a hearth pad, a good option in a condo or smaller unit where a built-in isn't practical but there's still an exterior wall available for direct venting. For most existing houses in the city, an insert is the least disruptive way to modernize.

Yes. You'll need a permit through your municipal building department, and the gas connection itself has to be done by a technician licensed under the Technical Standards and Safety Authority, following the CSA B149 gas code. Most established Toronto hearth dealers coordinate both the building permit and the TSSA-licensed gas work as part of the job, which saves you from managing two separate approvals on your own.

Direct-vent is the standard here, and for good reason—vent-free gas appliances that burn into the room aren't approved for use under Ontario's gas code, so nearly every unit your local dealer installs will be direct-vent or B-vent, drawing combustion air from outside and exhausting it back outside through sealed venting. That is a simpler decision than in some U.S. markets where vent-free is common; in Toronto, the code has largely made the choice for you.

Plan on an annual check, ideally in September or October before the first cold snap rather than mid-winter when TSSA-licensed technicians are booked solid across the GTA. A service visit covers the burner, pilot assembly, gas connections, and venting, and typically runs $150 to $250 CAD. It's a lighter job than a wood chimney sweep, but skipping it on a unit running daily through a five-month heating season is how a pilot or ignition fault shows up on the coldest night of January.

Gas wins on convenience for most city addresses, since Enbridge Gas already reaches nearly every block and a direct-vent unit fires instantly without a permit headache tied to solid fuel. Wood still works well outside the core or on larger rural-fringe lots where sugar maple and red oak are easy to source, but it requires a WETT inspection for insurance and often isn't allowed in condos. Electric is the fallback for renters, condo units without exterior venting access, or anyone who wants a simple $500-$1,600 install with no gas line or chimney involved at all—Hydro One, Toronto Hydro, and Alectra Utilities customers pay around $0.128 per kWh, which keeps running costs reasonable for supplemental use.

Most modern gas fireplaces can—turn it on and off from the couch with a remote, or set a room temperature and let the fireplace hold the comfort zone for you. If low maintenance matters to your family, this is the feature set that makes gas the convenience pick over wood and pellet.

Because a fireplace is an iceberg—there's more behind the wall than in front of it. A low quote often covers only the unit; the full scope includes vent pipe, gas line or electrical, framing, and the tile or stone that has to come off and go back on. Make every bidder price the whole job. If a dealer can't speak to the full scope with confidence, that's your signal to keep looking.

If it was installed more than 15 years ago, probably. Older gas fireplaces keep a standing pilot light burning all the time, and that little flame can cost a couple hundred dollars a year. Newer models use pilot-on-demand ignition—the pilot lights only when you use the fireplace and goes out when you turn it off.

An insert is a fireplace that slides into a pre-existing wood-burning fireplace—if you don't have one, there's nothing to insert it into. A zero-clearance fireplace is built into a framed wall, which makes it the answer for remodels and new construction. Simple test: existing masonry fireplace means insert; blank or framed wall means zero-clearance.
