A compact island town with an old core, riverside lots and four-storey buildings

Census 2021 counted 11,638 residents on about 5.5 km², up 8% since 2016, according to Centris. The town’s own portrait puts the 2024 estimate at 11,900. The site planning by-law that came into force in November 2025 splits the town into sectors, and each sector has its own housing.

Brucy and the Grand Boulevard: the original centre

The by-law says a good part of the centre dates back nearly 50 years and belongs to the original fabric of the island. Brucy first housed working families, then summer visitors. Before the autoroute du Souvenir opened, regional traffic ran along the Grand Boulevard. The same text notes that many buildings here went years without renovation. Frames from that era seldom match today’s catalogue sizes, so we build to the opening.

The heritage core: clay brick, stone and two storeys

By-law 748 describes the oldest streets as the first settlement, with deep lots, narrow frontages and mostly two-storey buildings in clay brick and stone. It names sills, lintels and galleries as period details. A brick opening with a stone sill has a fixed outline. A new frame has to fit the sill and lintel you already have, so we bring frame samples to check the proportions.

Riverside streets: large lots, mature trees and a flood zone

The by-law describes this sector as curving streets that follow the shore, houses set back from the road and large lots under mature trees. It also says part of the sector lies in a flood zone. Ask the town about extra rules before you change basement openings in that part. Above grade, the work follows the same steps as anywhere else.

Île-Bellevue and Maricourt: buildings with boards and neighbours

Île-Bellevue stands out in the by-law for four-storey buildings of homogeneous design, with a rail line and the autoroute du Souvenir close by. Maricourt has multi-unit buildings on a wooded hillside. If you own a unit, read your declaration of co-ownership before you order, since that document settles who has the say over outside windows and doors. Because of the rail line and highway, sound is a fair question to raise at the estimate.

Do I need a permit to replace windows or doors in L’Île-Perrot?

It depends on how many windows and whether the size changes. The town’s by-law 677 draws the line at half of the building’s windows. Doors have no line of their own in that table, so ask the town about a door. Call the one-stop desk at 514 453-1751.

The half-of-the-windows rule

The permit table in by-law 677 says a permit is needed to replace more than 50% of a building’s total windows, or to change the size of openings. It lists replacing less than 50% of the windows under maintenance and repair, with no permit and no certificate. Count every window in the building, then compare. The compilation we read is dated 6 February 2026, and it states it has no legal value.

What to file when a permit applies

For a replacement above the half mark, by-law 677 asks for the detail of the windows to be installed and their locations. We prepare that list for you with each opening’s size and position. The town’s permit page says you apply at town hall or online, that only some permits are online, and that payment is made at town hall.

Site planning review (PIIA) by-law 748

By-law 748 came into force on 14 November 2025 and replaced by-law 620. Its table lists renovation that changes the number or size of exterior doors and windows, except when only a part hidden from the public street is affected. Same-size replacement is not on that list. The advisory planning committee gives its opinion on PIIA files, and you reach it through the same desk.

Why the town asks before work starts

The permit page tells owners to check with the town before they begin, and the town’s special planning program for the Grand Boulevard and boulevard Perrot area shows it pays close attention to building quality there. A short call before you order is cheaper than sorting out a missing permit after the install.

How we serve L’Île-Perrot, from the Grand Boulevard to Brucy

Grand Boulevard and the centre

25 km and about 24 minutes from our Saint-Laurent showroom, without traffic. Houses near the Grand Boulevard are often among the town’s older ones, so we check the condition of the brick mould and sill around each opening during the visit.

Boulevard Perrot and the heritage core

25 km and about 25 minutes, measured to the Sainte-Rose-de-Lima church. On the oldest streets we match the proportions of the brick and stone opening, and we show you a frame sample against your wall before you decide.

Pointe de Brucy and the riverside

26 km and about 27 minutes. For a riverside lot with large trees, we talk about which walls face the water, and we leave basement openings to a second conversation after you have heard from the town.

L’Île-Perrot is 25 to 26 km from our showroom

Our crews start at 1190 Rue Bégin in Saint-Laurent and cross to the island. The times are rounded OpenStreetMap driving figures to each named place, with no traffic added.

Questions L’Île-Perrot owners ask

Must I get a permit before replacing windows in L’Île-Perrot?

Replace more than half of the building’s windows, or change the size of an opening, and by-law 677 calls for a permit. Replace less than half and it calls for none. For doors, no line in the table settles it, so call 514 453-1751 before you order.

Which PIIA sector does my house fall in?

By-law 748 divides the town into sectors, among them the centre, the heritage core, the riverside, Île-Bellevue and Maricourt. The review applies where the number or size of exterior openings changes, and it skips changes that only touch a part hidden from the street. Ask the town which sector your address falls in.

I own a condo on Île-Bellevue. Where do I start?

Start with your board and your declaration of co-ownership. That document settles who has the say over outside windows and doors. We quote each opening on its own line, which a board can approve one item at a time.

Is L’Île-Perrot far from your Saint-Laurent showroom?

From 1190 Rue Bégin in Saint-Laurent it is 25 to 26 km, about 24 to 27 minutes without traffic. The estimate at your house is free, and the written quote comes after it.

Will Québec pay part of my window bill?

Rénoclimat pays up to $300 for each eligible window and caps a house at $4,500, according to quebec.ca on 13 November 2026. We read the program steps with you so the file is ready before the install.
