Pesticide Notification Rules & Bylaw Exemptions - London
In London, Ontario, rules about pesticide notification and exemptions are governed by provincial pesticide law alongside municipal practices for city-managed lands. This guide explains how notification typically works, which exemptions commonly apply, who enforces the rules, and how residents can report or appeal actions. It summarizes practical steps for property owners, tenants, contractors and community groups to comply with notification requirements and to request permits or exemptions where available. For provincial regulatory text see Ontario Regulation 63/09 (Pesticides).[1]
What the rules cover
Pesticide notification rules address when and how residents, applicators and municipal crews must tell others before applying pesticides, especially herbicides and insecticides used for cosmetic lawn care or landscaping. Exemptions can apply for public health vector control, agriculture, forestry, and some municipal maintenance activities. Local implementation may include additional notification practices on city property and specific program notices to residents.
Common exemptions
- Public health vector control (e.g., West Nile virus mosquito control) is routinely exempt from cosmetic bans.
- Agricultural and forestry uses operated under provincial rules are generally exempt from municipal cosmetic pesticide restrictions.
- Emergency control for invasive species or immediate safety hazards may be exempt, depending on the regulatory instrument.
Notification best practices
When notification is required, common practical steps include posting visible signs at treated properties, distributing written notices to neighbours, and providing advance notice periods for scheduled treatments. Applicators should keep records of dates, products used, label instructions followed and the notification method.
- Post visible signage at least 24 hours before and for a specified period after treatment when required by policy or contract.
- Provide written notice to adjoining properties and building managers when required.
- Keep treatment records and product labels for compliance and inspection.
