Do permit rules change from one city to the next?

Yes, and sometimes from one borough to the next. We read each city’s own pages on 12 November 2026. Here is how four kinds of rule compare, so you know what to ask before you order.

Four Montréal boroughs, four different answers

LaSalle and Verdun ask for a permit even when the new window or door has the same size as the old one. Lachine says a permit is generally not required for same-size models, except in a site planning (PIIA) sector. Saint-Léonard says a permit is needed to replace them, and it does not define a minor job, so we ask the counter. Where a permit applies, all four pages set the fee at $9.80 per $1,000 of work, with a $167.40 minimum for a residential building.

Laval, Châteauguay and Rosemère: same size can mean no permit

Laval lists same-size replacement as work that needs no permit, but asks for one when an opening is less than 1.5 m from the property line. Châteauguay needs no permit when size and position stay the same, though a PIIA approval can still apply. Rosemère allows renovation of $20,000 or less before taxes without a permit, if the openings, the look and the structure stay the same.

Old villages and heritage buildings add a review

In Châteauguay, a house built before 1920 goes to a PIIA review for window work, under by-law Z-3600. In La Prairie, owners in the heritage site need the culture ministry’s authorization for all exterior work, as the Quebec heritage page explains. In Terrebonne, by-law 1011-003 sends changes to doors and windows on inventoried heritage buildings to a PIIA approval.

Declarations, size tests and small-job limits

Terrebonne asks for a declaration of works before an exterior renovation, and its DT-01 form says it is not a permit. Brossard requires a permit unless the openings are not altered. In La Prairie, by-law 1252 treats a window that keeps its size as minor maintenance, but only under four conditions, including a total under $5,000.

How to pick the right page

Find your town in the five regions above. If it sits in a group, such as the West Island, the North Shore or the South Shore, open the group page first. It links each town and names the rules that differ between them. If you live between two towns, pick the nearer one and call us.

What our estimate covers anywhere in the region

The estimate is free and takes place in your home. An estimator measures every opening and checks the frames. You then receive a written quote. It lists each opening, so you can attach it to a permit request where your city asks for one.

How scheduling works by region

Call (514) 387-0001 Monday to Friday from 9:00 to 16:00, or use the quote form, and tell us your town. The steps stay the same everywhere. Only the drive changes, from 10 km to Chomedey to 36 km to Vieux-Terrebonne from our showroom, measured without traffic.

Greater Montréal is 10 to 36 km from our showroom

Questions about our service area

Do you serve my town?

Yes. We serve all of Greater Montréal: the island, Laval, the North Shore and the South Shore. Find your town in the list above. If it is missing, call (514) 387-0001 with your address and we confirm.

How do I get a price for my windows and doors?

A price comes from a written quote after an in-home estimate. An estimator measures your openings first, so the quote fits your home. The estimate is free.

Who installs the windows and doors?

Our own crews install them. We are a licensed contractor, RBQ 5735-2130-01, and we have installed windows and doors for 35+ years.

Do I need a permit?

It depends on your city, and sometimes on your street. Some cities ask for a permit even for a same-size swap, and others do not. The section on permit rules above compares them, and each town page gives the details and the official link.

Is there a government grant for new windows?

Quebec’s Rénoclimat program pays up to $300 per window. The cap is $4,500 for a house and $6,000 for a duplex, a triplex or a multi-unit building. It applies to new files since October 1, 2026, and conditions apply. See quebec.ca for the latest rules.
