Egress Windows in Montreal: Why They're Essential for Safety, Comfort & Building Code Compliance

A Homeowner's Guide to Regulations, Safety Benefits, and Installation

What Is an Egress Window?

An egress window is a code-compliant window designed to provide a safe emergency escape route from a basement or bedroom while also allowing emergency responders to enter if necessary. In Montreal and throughout Quebec, egress windows are an essential safety feature whenever a basement contains a sleeping area. Beyond code compliance, they transform dark basements into bright, comfortable living spaces by increasing natural light and ventilation.

Why Egress Windows Matter

Whether you are finishing a basement, creating an in-law suite or renovating an older home, installing a properly sized egress window is one of the smartest investments you can make. During a fire or emergency, stairways may become inaccessible. A compliant egress window provides an alternative escape route that can save lives. It also helps emergency personnel gain rapid access to the home when every second counts.

Modern egress windows also improve the overall functionality of your basement. They introduce significantly more daylight, improve airflow, reduce the feeling of being below grade and make finished spaces feel larger and more welcoming.

Quebec Building Code Requirements

The Quebec Construction Code requires emergency escape windows to provide a minimum unobstructed opening of 0.35 m² (3.77 sq. ft.) with no clear dimension smaller than 380 mm (15 inches). These measurements refer to the clear opening when the window is fully open, not the glass size. The window must be operable from inside without keys, tools or special knowledge and remain open without being held. If a window well is installed, sufficient clearance must allow the sash to open fully and permit safe escape.

Choosing the Right Window

Casement windows are generally considered the best choice for egress applications because nearly the entire opening becomes usable when the sash swings outward. Sliding windows can sometimes meet code requirements but usually need to be substantially larger since only one side opens. Selecting the appropriate style depends on the available wall space, foundation opening and the intended use of the room.

Benefits Beyond Code Compliance

• Provides a safe emergency escape route.

• Helps create a legal basement bedroom.

• Brings more natural light into the basement.

• Improves ventilation and indoor comfort.

• Can increase resale value and buyer appeal.

• Modern energy-efficient windows help reduce heat loss and improve year-round comfort.

Professional Installation Matters

Installing an egress window often requires enlarging the foundation opening, waterproofing the new opening, adding proper drainage and ensuring the surrounding structure remains sound. Depending on the municipality or Montreal borough, permits may be required when altering a foundation opening. Working with an experienced installer like Selcan Windows and Doors helps ensure the project complies with local regulations while delivering long-term performance and protection against water infiltration.
