Where the gas line actually reaches in Mirabel.

Only in parts of it. Énergir runs mains through the more developed sectors near Saint-Janvier and the commercial and industrial land around Montréal-Mirabel airport, but a lot of Mirabel's newer subdivisions and rural stretches were never built out with gas service. Before you shop for a fireplace, it's worth having your address checked against Énergir's network—if you're not on it, propane is the standard fallback and most direct-vent gas fireplaces carried by local dealers can be configured for either fuel.

Typical installs run $6,000 to $15,000 CAD. A direct-vent insert going into an existing masonry firebox on a street already served by Énergir sits toward the low end. A new built-in unit for a renovation or addition, especially one that needs a propane tank set and line run because the property sits outside Énergir's coverage, lands toward the top. The gap between those two scenarios is almost entirely about how much gas infrastructure already exists at your address.

Yes. Propane is the standard workaround for the many Mirabel properties outside Énergir's mains, whether that's a rural lot near the edge of town or a newer subdivision built without gas service. A local dealer helps arrange the propane tank set and line run and coordinates with a licensed gas fitter—the fireplace itself doesn't need to know the difference, since the same direct-vent models work on either fuel with the correct orifice kit. Budget a bit extra over the base install cost for the tank and line work.

Yes. You'll need a building permit through Mirabel's municipal building department, and the gas connection itself has to be done by a licensed gas fitter under the CSA B365 installation code. Most local dealers who help with projects here handle the permit application and coordinate the gas fitter's work, so you're not managing two separate trades and two sets of paperwork yourself.

Mostly geography and cost. Hydro-Québec electricity runs around $0.078 per kWh, among the lowest residential rates in Canada, which makes electric heat a genuinely cheap default rather than a compromise. Wood is the other mainstay—sugar maple, yellow birch, American beech, and red oak are all readily available across the Laurentides region, and a lot of Mirabel properties have the space to store and season a few cords. Gas only makes sense where Énergir's mains already run, which is a smaller footprint than either of those two options.

No—unvented gas appliances aren't permitted for residential use under Canadian code, Mirabel included. Every gas fireplace or insert installed here needs to be a direct-vent unit, pulling combustion air from outside and exhausting it back outside through sealed venting. That's not a local quirk, it's a national standard, but it's worth knowing upfront since some online listings from the U.S. market advertise vent-free models that simply aren't legal to install on this side of the border.

It depends mostly on whether your street has Énergir service or you're comfortable running on propane. Where either fuel is available, a gas insert with a stainless liner run through the existing chimney is a straightforward retrofit for an old wood-burning masonry fireplace, generally landing in the lower half of the $6,000-$15,000 range. If you'd rather keep burning wood—sugar maple and yellow birch are the local favourites—a certified low-emission insert is the more common upgrade path instead, and it sidesteps the gas-availability question entirely.

Plan on an annual check, ideally before the cold sets in around September or October rather than mid-winter when technicians are booked solid. A licensed gas fitter checks the burner, pilot assembly, gas connections, and venting, and cleans the glass. It's a lighter job than a wood chimney sweep, but on a unit that's your primary evening heat source through a five-month season, skipping it is how a pilot or ignition problem turns up on the coldest night.

Given how limited Énergir's coverage is here, gas usually only wins when your address is already on the network or you're fine adding propane. Wood is the traditional choice across the Laurentides region—sugar maple, yellow birch, American beech, and red oak all season well locally—though any wood-burning appliance still needs to meet certified low-emission standards and, for insurance, generally needs a WETT inspection. Pellet stoves, using regional brands like Granules LG, Energex, or Trebio at roughly $400-$575 a ton, split the difference: cleaner-burning than open wood and not dependent on gas infrastructure, though they do need power for the auger and blower. A lot of Mirabel households end up on electric or wood as primary heat and treat gas as a convenience add-on only where the mains already reach.

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.

Fireplaces are like icebergs—bigger behind the wall than in front of it. Replacement means removing the surrounding tile or stone (the finish material laps onto the fireplace face), pulling the old unit, setting the new one in the same enclosure, and re-finishing the wall. A hearth professional can determine what's behind your wall without demolition during an in-home preview.

Open fireplaces suck—literally. As the fire burns, it consumes air your furnace already paid to heat and pulls it out through the chimney, so the house is actually colder after the fire goes out than before you lit it. An insert fixes this: it seals the chimney, puts fixed glass across the front, and turns that hole in your house into a real heat source.
