Environment and Climate Change Canada is leading the implementation of the agreement and working with a number of departments, agencies and agencies on both sides of the boarder representing governments, Aboriginal peoples, water basin management agencies and other local public bodies. Canada is cooperating with the Ontario government as part of the 2014 Great Lakes Water Quality and Health Agreement on Water Quality and Ecosystem Health and is working with Canada, which coordinates the activities of eight federal departments and three provincial departments to support the implementation of the GLWQA. The United States and Canada first signed the agreement in 1972. It was amended in 1983 and 1987. In 2012, it was updated to improve water quality programs that ensure the ”chemical, physical and biological integrity” of the Great Lakes. Until 1978, the two countries expanded their approach to combating the many sources and types of pollution in lakes. The 1978 Great Lakes Water Quality Agreement set itself the goal of ridding the Great Lakes of persistent toxic substances – pollutants that come from many sources and can harm the health of all species because they remain in the environment for a long time, with an approach that takes into account the entire ecosystem. A 1987 protocol to the 1978 Great Lakes Water Quality Agreement added specific efforts to rehabilitate the most polluted areas of watersheds, known as ”Areas of Concern,” and to develop management plans for the elimination of pollutants at sea level. The IJC was tasked with assessing progress in achieving the 1972 and 1978 objectives every two years and held meetings every two years before concluding each biannual report on the progress of the work. The 2012 agreement will help the United States and Canada jeopardize the water quality of the Great Lakes and strengthen measures to anticipate and prevent environmental damage. The new provisions address invasive aquatic species, habitat degradation and the effects of climate change and support further work on existing threats to the health and environment of Great Lakes Basin populations, such as harmful algae, toxic chemicals and ship releases. Through the GLWQA, in Canada and the United States, programs, technologies and other measures needed to better understand the Great Lakes ecosystem and restore and protect water quality and ecosystem health will be developed by GLWQA, Canada and the United States, in consultation and cooperation with the governments of the federal states and provinces. , Densosten, Dener Non-Nations and Métis, local authorities, watershed management agencies and other local public bodies.
From 1918 to the late 1960s, the IJC repeatedly reported pollution problems in the Great Lakes and their linkage channels as part of its border treaty jurisdiction. These reports included recommendations for action that formed the basis for the first Great Lakes Water Quality Agreement in 1972. Canada and the United States have agreed to reduce pollution in industries and communities and limit the amount of phosphorus that has entered lakes, resulting in excessive algae growth, particularly in the Erie Sea. New laws have reduced phosphorus levels in household detergents and municipal treatment plants have been upgraded or expanded. Eriesee has recovered rapidly thanks to these efforts, and the value of binational cooperation for environmental rehabilitation in all lakes has been touted internationally as an unprecedented success.
