OBC DIVISION B · PART 3 · SECTION 3.11 — PUBLIC POOLS

Does an outdoor public pool need a fence or enclosure in Ontario?

Yes. Outdoor public pools must be enclosed by a fence or equivalent barrier with self-closing, self-latching gates to keep people out when the pool is unsupervised. A minimum height of 1.2 m (4 ft) is the common benchmark, with some municipalities requiring more.

Code reference
Outdoor public pools are required to be enclosed by a barrier that restricts unauthorized access to the pool area when it is not open or supervised. The enclosure must be of adequate height, resist climbing, and have gates or doors equipped with self-closing and latching hardware so the pool cannot be entered casually outside operating hours.

Paraphrased for clarity — open this provision in the BUILDAiD Library for the exact wording.

What this means in practice

The enclosure requirement layers with other regimes: Section 3.11 governs the public pool itself, O. Reg. 565 addresses operational access control, and municipal pool enclosure bylaws add local height and construction rules that sometimes exceed 1.2 m (4 ft). Design the fence to resist climbing, with no horizontal members forming a ladder and controlled gaps under and through the barrier. Gates need self-closing, self-latching hardware, with latches positioned out of easy reach of small children. Buildings can form part of the enclosure if their doors are controlled.

Plain language

Outdoor public pools must be fenced so children cannot wander in when no one is watching, with gates that swing shut and latch by themselves. Fences are generally at least 1.2 metres (4 feet) high, and some cities require taller ones.
