A permit is required to replace exterior doors and windows with models that have the same dimensions.

Since, in order to receive a permit, the models submitted must comply with requirements, it is strongly recommended you obtain your permit prior to signing a contract for your project.

Exterior walls

If your work is to be done on an exterior wall, before ordering your supplies, please carefully read the Sud-Ouest borough’s document on doors and windows (Appendix F of the Sud-Ouest urban planning by-law, in French).

It identifies the original types of doors and windows and the authorized replacement models, according to the type of building. If your windows or doors are original, you must preserve exactly the same appearance (form, materials and model).​

All exterior walls are included in this requirement, except one that leads to a rear yard. Certain exceptions apply if your property is an architecturally significant building, in which all exterior walls are included, or if it is located near the Canal de Lachine.

It is important that you check to see if your building is recognized as significant or architecturally significant, or if it is located in a significant sector in order to fully understand the replacement requirements applicable to your property.

Rules to follow

• Use of polyvinyl chloride (PVC) on the exterior of windows, including the frames, is prohibited throughout the Sud-Ouest. However, you can use a hybrid model.
• For an architecturally significant building (a property of local interest, a property subject to the Cultural Heritage Act, and places of worship identified in Appendix B), exterior window cladding must be in wood or aluminum
• For a significant building and a building located in a significant sector, windows can be in wood, aluminum or hybrid
• Skylights, windows and French doors on a home must comply with “Energy Star®” certification according to criteria established by Natural Resources Canada for Climate Zone 2
• Original glass block must be preserved and reinserted in the opening
• Original stained-glass windows must be preserved and reinserted in the opening
• Except in the case of an architecturally significant building, modification of the colour of an original architectural component is allowed
