Do I legally need security bars on my basement windows in Ottawa?

No, Ontario Building Code does not generally require security bars on basement windows for existing residential homes. Security bars are a personal security choice, not a standard legal requirement for homeowners.

That said, there are important code considerations that actually work against bars in certain situations.

Egress Requirements Are the Key Code Factor

The Ontario Building Code requires that basement bedrooms (and rooms used as sleeping areas) must have at least one window that meets egress requirements - meaning it must be large enough for a person to escape through in an emergency. The minimum opening is typically 0.35 m² with no dimension less than 380mm. If you install security bars on an egress window, those bars must be openable from the inside without tools or keys - otherwise you're creating a fire safety hazard and a code violation.

This is the one area where bars can become a legal issue. A basement rec room or storage space has more flexibility than a basement bedroom.

Ottawa-Specific Context

Ottawa doesn't have a municipal bylaw specifically mandating security bars on residential properties. Some rental properties may have additional requirements depending on the building classification, but for a standard single-family home, bars are entirely optional. If your property is a rental unit, it's worth confirming with Ottawa Building Services or a licensed contractor, as rental housing standards can differ.

Practical Alternatives to Consider

Many Ottawa homeowners opt for laminated security glass, window sensors tied to a home alarm, or window well covers for below-grade windows - all of which improve security without the egress complications that bars create.

If you're replacing basement windows and want to address both security and energy efficiency at the same time, that's a great opportunity to upgrade to a proper egress-compliant window with laminated glass.
