Tim Fletcher has dedicated over 35 years to advancing water quality initiatives with the Ontario Ministry of the Environment, Conservation and Parks (MECP). His work has primarily focused on the development of water quality standards, both provincially, and nationally through his active involvement with the Canadian Council of Ministers of the Environment (CCME).

Throughout his tenure at MECP, Tim has provided expert scientific support and strategic guidance across a range of environmental programs, including source water protection, toxics reduction, Great Lakes water quality, and the Wastewater Surveillance Initiative launched in response to the COVID-19 pandemic.

In recent years, Tim has expanded his portfolio to include Pesticides Management, where he leads efforts that uphold and advance Ontario’s Pesticides Act and Regulation.
