Fence height rules and permits in Canada

There is no Canada-wide fence-height rule

Municipal bylaws control ordinary residential fence height in many communities. A fence that is acceptable in a rear yard may be too high in a front yard, and pool enclosures often have a separate permit or safety regime.

Four official examples

Edmonton: the city's current zoning material uses 1.3 m as the normal maximum in front yards and 2.0 m in other yards. A development permit is required for an over-height fence or privacy screen. Edmonton also says an ordinary fence does not require a building permit unless it is part of pool or hot-tub screening.

Calgary: the Land Use Bylaw sets 1.2 m for the portion of a residential fence extending between the front façade and the front property line and 2.0 m in other cases, with separate provisions for gates and special situations.

Ottawa: the fence bylaw uses a lower maximum in a residential front yard than in other yards and has special visibility-triangle rules at corners and driveways.

Toronto: the city says fence height depends on the location of the fence and the property type. Pool enclosures have additional requirements, including a zoning certificate and pool-fence enclosure permit.

What can change your fence rule?

• Front, side or rear yard location
• Corner lot and driveway sightlines
• Pool or hot-tub enclosure
• Fence material
• Privacy screen on a deck or rooftop terrace
• Grade changes or retaining walls
• Heritage or site-specific controls

Do not copy a height from another city

Even nearby municipalities can use different measurements and approval systems. Search your own municipality and confirm the current bylaw before ordering material or setting posts.
