Montréal, Quebec contractors who apply pesticides must follow municipal rules that limit cosmetic and municipal pesticide use and require permits or authorizations for some activities. This guide explains how the city regulates pesticide application, who enforces the rules, what common violations look like, and practical steps to obtain authorizations, comply on site, and appeal enforcement decisions.

Scope of the municipal rules

The City of Montréal restricts certain pesticide applications on municipal land and in public spaces and sets conditions for permitted uses. Contractors should verify whether a specific treatment is allowed, requires a permit, or must follow label, provincial and municipal conditions before starting work.

Always confirm permit requirements with the city before scheduling pesticide work.
