Fish Consumption Advisories
Canada is renowned for its pristine lakes and rivers, attracting recreational and subsistence fishers who enjoy and consume the diverse fish species they catch. There is growing concern, however, that certain fish species in some of Canada's freshwater bodies have acquired elevated mercury levels. Mercury released from human activities can be converted in the environment to a highly toxic form called methylmercury, which can bioaccumulate and biomagnify in fish tissue, particularly in predatory species like pike, walleye and bass. The consumption of mercury contaminated fish is one of the main pathways for mercury exposure in humans, and may pose serious health risks, particularly for young children and the developing fetus.
In addition to creating regulatory tools to reduce mercury releases to the environment, federal, provincial and territorial governments have placed fish consumption advisories on individual species, lakes and in some cases on entire regions, in order to prevent high levels of mercury exposure to consumers. The links below provide information on some fish consumption advisories that are available electronically. People who catch and consume fish as a staple part of their diet should consult local fishing and health authorities to obtain information about local advisories.
Examining Fish Consumption Advisories Related to Mercury Contamination in Canada (2001) outlines federal, provincial, and territorial roles, responsibilities and procedures related to fish consumption advisory development across Canada. This document is not intended to serve as a reference guide for these advisories because they can change over time. The links below provide up to date information on current advisories in various regions across Canada and/or contacts for the responsible agencies.
