You can build a fence on the property line only if both property owners agree. Otherwise, you must build your fence 1" (one inch) inside your property line.
Location and height limit:
Front Yard 0.75 m (2.5 ft)
Side or Back Yard 1.80 m (6 ft)
If your fence is being built around a swimming pool, you will need to contact the Municipal Law Enforcement & Licensing Department. Applicants must apply through the CloudPermit.ca online permitting system.
For more information, you should read the Fence Guidelines.
