2.1 Introduction
Health Canada (HC) evaluates the risks to human health and the environment associated with the use of
pesticides and regulates pesticide products in Canada. In the interest of increasing the availability of realworld data for use in pesticide risk assessments, HC is implementing a Canadian Water Monitoring
Program for Pesticides (CWMPP). As part of this program, water samples are analysed to determine the
concentrations of pesticides present in Canadian waters. Federal laboratories will analyse approximately
200 chemicals (i.e., pesticide active ingredients and transformation products) in water from various
regions across Canada. The information is being collected to use in pesticides regulatory decisions, as
appropriate.
2.2 Objectives of the Requirement
HC requires the services of a contractor to carry out water sampling at specified sites in the Lower
Mainland region of British Columbia in 2025-26 and up to two option years. The information is being
collected to use in pesticides regulatory decisions, as appropriate. In support of HC’s goal of increasing
transparency, the generated pesticides data will be shared publicly through the Government of Canada
Open Data portal.
