Pool Fencing

Drowning is a silent danger and the second leading cause of death for Canadian children. If you have a pool, it's important to build a pool fence that meets local by-law requirements.

Keep young children safe and build a four-sided fence/barrier to separate the pool from the rest of the yard.

Information about Pool Fences

The purpose of pool fencing is to isolate the swimming pool, or yard where the pool is located, by completely enclosing it.

Find out what your municipality defines as a pool; many inflatable pools require proper fencing. It is important to check with your local municipality to find out what by-law requirements will apply to your property.



For example, the City of London’s Swimming Pool Fence By-law PS-5 requires

  • A fence which is a minimum height of 1.5 metres (4.9 feet);
  • Gates that are self-closing and self-latching;
  • Specific gap or opening sizes in the fence depending on the design and stay of the fencing used.

Municipalities require a swimming pool fence permit be obtained before installation of the pool. This permit will ensure the municipality conducts an inspection to confirm by-law compliance. 1
