Cosmetic Pesticides – Provincial Policies & Municipal Bylaws: Lessons Learned & Best Practices

The report analyzes the landscape of cosmetic pesticide bans in Canada, evaluating the effectiveness of various provincial and municipal regulatory frameworks. It argues that the most protective laws utilize 'white lists' of approved low-risk pesticides, maintain a broad scope of coverage across all landscaping elements, and combine legal prohibitions with robust public education and enforcement. The document highlights significant gaps in jurisdictions like Alberta and British Columbia, while praising the comprehensive approaches of Ontario and Nova Scotia.

• The most effective cosmetic pesticide initiatives are mandatory prohibitions supported by education programs, whereas voluntary programs involving only education and outreach reported only a 10-24% reduction in pesticide use.
• Regulatory frameworks based on 'white lists'—which identify safe or low-risk pesticides approved for use—are considered more effective than 'black lists' because the burden of proof for safety rests with the manufacturer rather than the government.
• Broad-scope bans that cover all landscaping elements (e.g., Ontario and Nova Scotia) provide more protection than narrow bans that only prohibit cosmetic use on lawns (e.g., Manitoba, New Brunswick, and Newfoundland and Labrador).
• Common exceptions for golf courses, sports fields, and indoor environments are identified as weaknesses that can undermine the overall effectiveness and purpose of cosmetic pesticide bans.
• Implementation of Ontario's cosmetic pesticide ban led to significant environmental improvements, with water samples showing reductions between 80% and 83% for several common active ingredients, including 2,4-D, dicamba, and MCPP.
• The City of Toronto's evaluation of its pesticide bylaw from 2003 to 2008 found that reported cosmetic pesticide use on lawns by residents decreased by approximately 57%.
• Beyond public health, cosmetic pesticide bans offer additional benefits including improved soil complexity, reduced pesticide run-off into waterways, and the creation of more robust environments that attract birds, butterflies, and bees.
