First phase: 2011-2016

This action plan, the fifth since 1988, gave rise to some remarkable initiatives to protect and enhance the St. Lawrence River. Three major issues––water quality improvement, conservation of biodiversity and sustainable use—were the focus of all the initiatives implemented by federal and provincial departments and agencies, as well as by many stakeholders from riverside communities.

Over forty projects were jointly carried out by scientific experts from the eighteen federal and provincial departments that signed the action plan. Two programs were implemented to monitor the health of the river and develop forecasting models to better predict future changes in water and ecosystem quality.
