The Guide to Eating Ontario Sport Fish is published every two years by the Ministry of the Environment in co-operation with the Ministry of Natural Resources.
Staff at the Ministry of Natural Resources and Ministry of the Environment collect fish which are analyzed at the Ministry of the Environment laboratory in Toronto. The fish are analyzed for a variety of substances, including mercury, PCBs, mirex, DDT and dioxins. The 2011-2012 edition includes advice for sport fish from more than 1,950 lakes, rivers and streams around the province, incorporating approximately 60,000 test results performed on 10,000 fish samples.
The Sport Fish Contaminant Monitoring Program, which started in 1976, is the largest testing and advisory program of its kind in North America.
