In-ground and above-ground pools

A pool is defined as an artificial, outdoor basin designed for swimming, bathing, or any other water recreation.

This definition includes wading pools, garden ponds, whirlpool baths, and hot tubs of 2000 liters or more, which have a depth of 45 cm (18 in.) or more at any point.

New provisions concerning the safety of residential swimming pools

To tighten safety measures around residential pools, the Quebec government announced an amendment to the Residential Swimming Pool Safety Regulation effective July 1, 2021. The changes being put in place are in response to the recommendations made by several coroners to reduce the risk of children drowning. They apply to all types of pools, including above ground, in-ground and removable pools.

The provincial regulation renders the acquired rights provided for in section 5.13 of the City’s Zoning By-law 2008-43 null and void for the owners of swimming pools installed before November 1, 2010. If this applies to you, you have until September 30, 2025 to ensure that your pool fencing and any other installation surrounding your pool comply with the zoning by-law.

The regulation calls for improvements in equipment surrounding residential pools to reduce the risk of diving accidents. Residents wishing to obtain a permit for the installation of a new pool or to replace a pool feature will be required to conform to the new provisions.

  1. Pools equipped with a diving board must be installed in accordance with the BNQ 9461-100 standard in effect at the time of installation and require a plan and a siting plan;
  2. Chain link fence enclosures with a mesh size greater than 30 mm will be required to be slatted so as not to permit the passage of a spherical object greater than 30 mm in diameter;
  3. No structure or fixed equipment likely to be used to climb over the wall of a swimming pool or enclosure should be installed within one metre of the pool;
  4. No window should be situated within one metre of a pool or an enclosure, unless it is at a minimum height of 3 m from the ground or its maximum opening is 10 cm.

If you have any questions about whether your swimming pool complies or want to find out the steps to take to bring it into compliance, you can contact the Urban Planning, Permits and Inspection Department at 450-672-4444 or

An above-ground pool that is less than 1.2 m (3.9 ft.) higher than the adjacent ground level must be enclosed by a fence. The fence may be situated on or near the property lines or around the pool. The wall of a building with openings cannot be considered as a part of the enclosure to limit access to the pool.

The minimum height for all fencing is 1.2 m (3.9 ft.), and the fence must completely enclose the area. The clearance between the ground and the bottom of the fence may not exceed 10 cm (4 in.).

The fence must not allow any opening greater than 11 cm (4.3 in.) and must not be climbable.

An above-ground pool must be fitted with a safety ladder. If the pool wall of an above-ground pool serves as a fence, the ladder must be raised, removed, or locked, and must not be accessible when the pool is not under supervision. In all cases, any ladder and/or deck providing access to the pool must be enclosed by a fence and a gate that complies with city by-laws.

Any pool whose walls are not completely vertical, such as inflatable pools, must be fenced in.

Ancillary buildings used to cover pools are not permitted.
