The federal government is responsible to facilitate the PPWB and interprovincial issues. The Constitution gives the federal government the power to address differences among provinces. The Canada Water Act gives the authority to allow the federal government to be a member of the federal-provincial PPWB agreement. Disagreements amongst PPWB members can be referred to the Federal Court of Canada. Under the Master Agreement on Apportionment, the federal government is responsible to conduct and pay for monitoring.
Environment and Climate Change Canada is the lead federal department on water issues and represents Canada on international issues. Environment and Climate Change Canada conducts water quantity and quality monitoring for the PPWB. The department administers the Canada Water Act, and is responsible for source water protection on federal and Aboriginal lands, regulation of toxic substances, protection of fish habitat from deleterious substances, and assessing the state of the environment.
Agriculture and Agri-Food Canada was the founding federal member of the PPWB. The department works with Environment and Climate Change Canada to fulfill the federal responsibilities of the PPWB. The department is involved in promoting environmentally sustainable agriculture.
Other federal departments are involved in water issues. Although none of these departments directly participate in the PPWB, federal PPWB members would consult with them if needed. Health Canada is the lead federal department on the protection of drinking water and is involved with the regulation of toxic substances. Indian and Northern Affairs Canada is the lead federal department for Aboriginal lands. The Department of Fisheries and Oceans is the lead federal department to protect coastal and inland fish habitat. Transport Canada administers the Navigation Protection Act that ensures that all Canadians have access to navigable waters.
