You must obtain a permit to add a door or window, or if you want to replace them with models of different dimensions.

It is recommended that you receive your permit before signing a contract for your renovation project.

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

Certain exceptions apply:

  • Addition of an opening is allowed if a dwelling or an additional premises is added to a building, as long as the new component complies with the architectural characteristics identified in Appendix B for the particular landscape unit
  • You are not allowed to fill in the side window or transom window to a door.
  • Addition of a window below the ground floor that respects the alignment of a window located on the ground floor is allowed, except for a wall opening onto a semi-basement entrance

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.
  • In the case of partial or complete filling in of an opening on a rear wall, the lintel and sill must be removed and the same wall facing as that of the adjacent section of the wall must be used, while respecting the masonry treatment. Does not apply to an opening to a crawl space.
  • 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
