On-demand heat backed by Enbridge Gas, right across Mississauga.

Installed gas fireplace and insert projects in Mississauga typically run $6,000 to $15,000 CAD. An insert dropping into an existing masonry firebox with a gas line already nearby—common in Streetsville and Cooksville homes built with a wood-burning fireplace as the default—lands toward the low end. A new built-in unit for a basement remodel or a highrise renovation, where gas line extension and venting through an exterior wall have to be worked around condo board rules, pushes toward the top of that range.

Yes, and it's one of the more common calls we get from Mississauga homeowners in older neighbourhoods like Clarkson and Port Credit, where the original masonry fireplace was built decades ago for wood and hasn't been used in years. A gas insert typically slides into that firebox with a liner run up the existing chimney and a new line tied into your Enbridge Gas service, and most conversions land in the middle of the $6,000-$15,000 range depending on how far the gas line has to travel.

In Mississauga, the honest answer is almost certainly natural gas. Enbridge Gas serves the overwhelming majority of the city, from established neighbourhoods like Erindale and Meadowvale to newer builds near the airport corridor, so most homes already have a gas line to the furnace or range that a fireplace install can tie into. Propane is really only a fallback for the rare rural or semi-rural property at the edge of Peel region that Enbridge hasn't reached, and your local dealer can confirm your specific address in minutes.

Most will. Units with intermittent pilot ignition run on AA battery backup that kicks in automatically, which matters in a region that's seen its share of ice storms take down power for days at a time. A handful of models, including some from Valor, skip the battery entirely because the pilot's thermocouple generates its own current. If backup heat during a winter outage is part of why you're buying, ask your dealer to point you toward one of those ignition systems specifically rather than assuming every gas fireplace handles an outage the same way.

A gas fireplace is a built-in unit framed into a wall, the standard choice in Mississauga's newer subdivisions and highrise units where there's no existing masonry to work with. A gas insert fits into an existing wood-burning firebox, the common route in older Streetsville, Cooksville, and Port Credit homes that already have a chimney chase to reuse. A gas stove is freestanding on a hearth pad, similar footprint to a wood stove but running off the gas line instead of cordwood, a good option for a basement or rec room that never had a fireplace to begin with.

Yes. You'll need a building permit through the municipal building department, and the gas connection itself has to be run by a technician licensed through Ontario's Technical Standards and Safety Authority (TSSA), a provincial requirement that applies whether you're in a detached home in Meadowvale or a condo tower downtown. Most established hearth dealers serving the region handle both the permit application and the final inspection as part of the job.

Realistically, no. Canadian gas code is more restrictive on unvented appliances than what you might see advertised on U.S. retail sites, and the vast majority of gas fireplaces installed in Ontario are direct-vent, pulling combustion air from outside and exhausting it back outside through sealed venting. That's also simply the better choice for a tightly sealed modern condo or a well-insulated newer build, where an unvented appliance would add combustion byproducts to indoor air with nowhere to go. If a model you're looking at is marketed as vent-free, confirm with your dealer whether it's actually certified for use in Ontario before you get attached to it.

Plan on an annual check, ideally in September or October before the first cold snap rather than January when technicians across the region are booked solid. A standard visit covers the burner, pilot assembly, gas connections, and glass, and usually runs somewhere in the $150-$250 range. Skipping it on a unit that's running most days through a five-month Mississauga heating season is how homeowners end up with an ignition fault on the one weekend they actually need the heat.

For most Mississauga households, gas wins on convenience: instant heat with no wood storage, no ash, and none of the WETT inspection or CSA B365 paperwork that insurers attach to solid-fuel appliances. Wood still has a following on the larger lots in Erindale and Clarkson where sugar maple and red oak are easy to source, but it's a smaller share of installs in a city this dense. Electric fireplaces, running off Alectra Utilities or Hydro One power at roughly $0.128 per kWh, are the easiest retrofit for a condo or a room where venting isn't practical at all, but they don't carry the same heat output as a properly sized gas unit for a main living space.

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.

Four numbers tell you what fits: the front width, the front height, the back width, and the overall depth of your existing fireplace opening. Grab a tape measure, jot those down, and snap a photo of the wall—those two things do more to move your project forward than anything else you can do today.

Most fireplaces are a thin metal box—they heat fine, but you rely on the fan to move the warmth into the room. Radiant models use a thick cast-ceramic firebox, about an inch and a quarter thick, that soaks up the fire's heat and radiates roughly 25–30% more warmth into the room with no fan running. If you watch TV in the same room or want heat in a power outage, radiant is worth asking about.
