Pesticides utilisés à des fins esthétiques : politiques provinciales et règlements municipaux – Leçons tirées et meilleures pratiques

The report analyzes the regulatory landscape of aesthetic pesticides in Canada, noting that while over 200 municipal bylaws have been adopted since the 2001 Supreme Court decision in Hudson v. Spraytech, effectiveness varies by scope and enforcement. It highlights that 'white lists' of safe products and broad bans covering all landscaping elements are more effective than narrow bans limited to lawns. Evidence from Ontario and Toronto shows significant reductions in pesticide presence in water and usage (up to 83% and 57% respectively) following bans. The document recommends removing exceptions for golf courses, implementing permit systems, and combining legal mechanisms with public awareness and enforcement.

• Regulatory scope varies between broad bans covering all landscaping elements—seen in Ontario, Nova Scotia, Peterborough, and Montreal—and restricted bans that only apply to lawns, such as those in Manitoba, New Brunswick, and Calgary.
• The effectiveness of pesticide reduction measures differs significantly by approach: voluntary programs involving education and awareness resulted in only a 10-24% reduction in use, whereas an Ontario study found reductions of 80-83% in water samples containing common active ingredients after a ban was implemented.
• Between 2003 and 2008, the city of Toronto observed a 57% decrease in the use of pesticides for aesthetic purposes following the implementation of its regulations.
