What latch height does an Ottawa pool gate need?

Pool gates in Ottawa must have the latch positioned on the pool side of the gate, placed high enough that a young child cannot reach it — in practice, this means near the top of the gate.

The Ontario Building Code sets the minimum fence height at 1.2 metres (4 feet), and the latch must be located on the interior (pool-facing) side. The intent is straightforward: a child approaching the gate from outside cannot reach over or through to operate the latch. Most installers position the latch within the top 100 to 150 millimetres of the gate to satisfy both the letter and spirit of the requirement.

A few related details matter just as much as latch height. The gate must be self-closing and self-latching — meaning it swings shut and latches automatically without anyone pushing it closed. Propping a pool gate open, even temporarily, defeats the entire safety system. Gate openings and fence gaps must not allow passage of a 100mm sphere, which prevents small children from squeezing through or reaching through to manipulate hardware. Hinges should be positioned so the gate cannot be lifted off easily from the outside.

The City of Ottawa enforces these requirements under both the Ontario Building Code and the municipal Fence By-law. A bylaw officer can order you to bring non-compliant fencing up to standard, and more importantly, inadequate pool fencing is one of the most serious safety hazards associated with residential pools. Drowning is fast and silent — proper barriers are the single most effective prevention measure.

If you are installing a new pool or replacing aging fencing, make sure your contractor pulls the appropriate permit and that the fence and gate installation is inspected before the pool is used.
