Egress windows are those abiding by the specified rules to function as an exit point in case of a fire emergency. When talking about egress windows, it is important to keep updated with regulations as end-result of not having the right sized window can be hazardous.
Basements need to have windows that serve as an escape in case of an emergency. It is illegal to use any space as a bedroom without fulfilling the requisitions. As per the NBCC, the required specific size is:
A window should have unobstructed openings with an area of 0.35 m2 with no dimension lower than 380 mm. To make sure the unhindered opening meets these requisitions, you should measure between sills, sashes and jambs.

The NBCC states that bedrooms should meet the given requirements:
- Offer 5% of minimum light for the flooring of the room
- Offer sufficient ventilation for all year.
- Should be rightly sized to serve as an emergency escape and need no key to open from the inside.
