Permits and authorizations

Montréal Construction and Conversion of Buildings By-law (11-018) is now in effect in Pierrefonds-Roxboro.

Residential swimming pools safety

The safety of our children is a priority in our borough. Before you buy or install an in-ground pool, above ground or inflatable, we recommend that you contact the borough in order to know the by-laws in matters of security and development of the site. Don't forget that obtaining a certificate of authorization is compulsory before installing a pool. Please see the section "Certificate of authorization" below for more information.

A swimming pool must be enclosed or fenced in a manner to protect its access. A hedge or bushes do not constitute an enclosure. The enclosure or the fence must meet the following provisions:

  • Be at least 1.5 meter in height;
  • Prevent the passage of a spherical object 10 centimetres in diameter;
  • Have no fixture, projection or open parts enabling it to be climbed;
  • Any door in the enclosure must be equipped with a self-closing and self-latching passive security device installed on the inside of the enclosure.

An enclosure is not required for an above-ground pool surrounded by an integrated fence if the height of the pool wall and the integrated fence is at least 1.5 meters. However, the following conditions apply:

  • Any ladder or steps providing access to the pool must be surrounded by an enclosure and by a gate of at least 1.5 meter high, fitted with an automatic closure and an automatic locking device;
  • Should the above-ground pool be accessible by a terrace or a patio connected to the ground by steps or stairs, access to the pool must be prevented by one of the following methods:
    - The top of the stairs or steps must be closed by a gate of a minimum height of 1.5 meter, fitted with an automatic closing and an automatic locking device;
    - A fence must be placed across the terrace, patio or platform so as to block access to the pool.

In addition to these provisions, the provincial by-law pertaining to residential pool safety requires that a pool be completely separated from any building by an enclosure or a fence of at least 1.2 m in height.

Inspections will take place throughout the summer and statements of offence may be issued without further notice.
