The city of Montreal adopted a regulation on the sale and use of pesticides, which enter into force on September 2021 and January 2022 respectively.

The regulation prohibits and controls the sale of certain pesticides, including glyphosate, allowing only for the use of biopesticides. The new regulation will ban the sale of the most toxic household pesticides, but also pesticides used in agriculture. In all, 36 molecules will be prohibited by the regulations. 109 pesticides will be banned from sale to citizens from 2022, of which 35 are glyphosate base. The City will ensure that products banned from use are not sold to citizens. Human resources have been hired to ensure the application of this part of the regulation. Montreal will become the first city in Canada to ban and controls the sale of these products.

To operate on the territory of the City, any commercial pesticide applicator must obtain an annual permit beforehand, for a sum of $200. All commercial pesticide applicator must keep an annual record of their uses during the year and send it to the City. Sanctions are provided for in the event of breach. These sanctions can vary between $500 and $4,000, depending on the case. The license can be revoked in the event of a repeat offense.

The uses of synthetic pesticides will only be permitted for specific cases that represent threats to health (e.g. poison ivy) or tree survival (eg: emerald ash borer). No other use of pesticides, other than biopesticides authorized by the rules, will not be tolerated. The uses of synthetic pesticides will only be permitted in the following cases: outside buildings: rats, field mice, mice, wasp nests or carpenter ants. With regard to rodents, for example, it will be prohibited to use the most common and toxic rodenticides (brodifacoum, bromadiolone, bromethalin, chlorophacinone, difethialone, diphacinone, phosphine).
