Access to practical tools & resources to help Canadians better understand and conserve wetlands.


In 1972, Canada and the United States signed the Great Lakes Water Quality Agreement (GLWQA) in recognition of the urgent need to improve environmental conditions in the Great Lakes. The 1972 GLWQA established the commitment to restore and enhance water quality in the Great Lakes system. In 1978, the agreement was amended to introduce the concept of the ecosystem approach which recognizes the interconnectedness of all components of the environment and the need for an integrated perspective in addressing issues of human health and environmental quality. A 1987 amendment identified local Areas of Concern where beneficial uses of the ecosystem had been significantly degraded, and committed Canada and the United States to the remediation of these sites. In addition, the Protocol introduced other new annexes focusing on non-point contaminant sources, contaminated sediment, airborne toxic substances, contaminated groundwater, and associated research and development.
