Where Énergir's gas lines reach Varennes, a fireplace lights instantly.

Installed costs typically run $6,000 to $15,000 CAD. The lower end covers a direct-vent insert going into an existing masonry firebox on a street already served by Énergir, with a simple gas line tie-in. The upper end applies to new construction or a full remodel that needs venting run through an exterior wall, a new gas line extended from the street, or a propane tank and line installed for homes outside Énergir's service area. Confirming which situation applies to your address is the single biggest cost lever before you shop.

It depends on the street, which is why this is the first question to settle before anything else. Énergir's network covers a real part of Varennes, mostly along established corridors closer to the river and older parts of town, but plenty of newer subdivisions and outlying streets have no gas main nearby. A local dealer can check your address against Énergir's coverage or, if you're outside it, plan the project around a propane tank instead. Either path works, but they lead to different equipment and different costs.

Yes, and it's a common request in Vieux-Varennes and other older sections where stone or masonry fireplaces were originally built to burn sugar maple or yellow birch. A gas insert typically runs a stainless liner down your existing chimney and ties into either an Énergir line or a new propane tank, with the work falling under the CSA B365 installation code enforced through Varennes' municipal building department. If your current fireplace is an old open wood-burning unit, converting also sidesteps the WETT inspection insurers often require on wood appliances.

Often, yes, depending on the ignition system, and that matters more in Montérégie than in most places. Longtime residents here still remember the 1998 ice storm, which knocked out Hydro-Québec power across the south shore for days and, in some areas, weeks. A gas fireplace with a standing pilot keeps running through an outage with no electricity at all. Units with intermittent pilot ignition need a battery backup to fire the igniter—ask your dealer which system is on any model you're considering, since it's a real consideration in a region with a history of major ice events.

A gas fireplace is a built-in unit framed into a wall, the usual choice for new construction or a full renovation. A gas insert fits into an existing masonry firebox, which suits the many Varennes homes, especially in the older riverside sections, that already have a wood-burning fireplace and chimney chase to reuse. A gas stove is a freestanding unit on a hearth pad, similar in footprint to a wood stove but running off an Énergir line or a propane tank instead of cordwood. For most existing homes here, an insert is the least disruptive upgrade.

Yes. You'll need a building permit through Varennes' municipal building department, and the gas line itself must be run by an RBQ-licensed gas fitter under the CSA B365 installation code. Most local hearth dealers coordinate both the permit and the licensed gas work as part of the project, since the two pieces need to be inspected together before the unit is signed off.

Direct-vent units, which draw combustion air from outside and exhaust it back outside through sealed venting, are the standard and the safer choice for a home running through a full Quebec winter. Vent-free models are permitted in some situations but come with strict room-sizing limits and show up far less often in local installs. Given how tightly sealed many Varennes homes are built against a five-month heating season, most local dealers steer homeowners toward direct-vent so indoor air quality isn't a tradeoff.

Plan on an annual check, ideally in September before the first real cold arrives rather than mid-winter when technicians book up fast. A technician tests the burner, pilot assembly, and gas connections, checks the venting, and cleans the glass. It's a lighter job than sweeping a wood chimney, but skipping it on a unit running daily through a Montérégie winter is how a pilot or ignition failure shows up on the coldest night of the year. Budget roughly $150-$250 CAD for a standard visit.

Given how limited Énergir's coverage is here, the honest answer often comes down to your address first and fuel preference second. Where gas is available, it wins on instant, thermostat-controlled heat with no fuel storage. Electric fireplaces deserve serious consideration too—Hydro-Québec's rate of about 7.8 cents per kWh is low enough that electric heat is cheap to run, and install costs are a fraction of gas at $500-$1,600 CAD. Wood remains the traditional choice, with sugar maple, yellow birch, American beech, and red oak all common in the region, and it keeps working without power—a real advantage after storms like the 1998 verglas. Many homeowners here end up choosing based on which fuels their street and budget actually support rather than a single best option.

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.
