Swimming pools generally require a fence or enclosure of a specified minimum height with self-closing, self-latching gates to prevent unsupervised access, but exact requirements vary by province and municipality.
Pool fencing and enclosure requirements are primarily a life-safety measure to prevent drowning, especially for young children. While the National Building Code addresses some swimming pool enclosure conditions, most enforceable pool fencing rules come from provincial building codes and municipal bylaws. The required fence height, gate hardware, and setback from the pool edge can vary significantly by jurisdiction.

Ontario, Quebec, BC, and Alberta each set different pool fencing requirements through their building codes or separate pool safety regulations.
Many municipalities have pool fencing bylaws that are stricter than the provincial code, including setback, height, and material requirements.
CodeCan reports what the published building code says. It is not legal, engineering, or architectural advice, and it does not certify compliance. Building codes are adopted and amended provincially and enforced locally — always verify with your authority having jurisdiction (AHJ) before you build.
Most jurisdictions require a minimum of 1.2 m (4 feet), but some municipalities require 1.5 m (5 feet) or more. Always check local bylaws.
In many jurisdictions, if the pool wall height meets the minimum barrier requirement and the ladder is removable, a separate fence may not be required, but this varies by municipality.
Most municipalities require a permit for pool installation that includes fencing compliance, and some require a separate fence permit.
