Reducing phosphorus loads to Lake Simcoe and south-eastern Georgian Bay – Cumulative, estimated reduction in the amount of phosphorus reaching Lake Simcoe and south-eastern Georgian Bay due to stewardship projects

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Reducing phosphorus loads to Lake Simcoe and south-eastern Georgian Bay indicator reports the contribution projects funded by the Lake Simcoe Clean-Up Fund (April 2007 to March 2012) and Lake Simcoe / South-eastern Georgian Bay Clean-Up Fund (April 2012 to March 2017) are making toward reducing the amount of phosphorus reaching the water bodies from their watersheds. Changing how land is managed in the watershed helps to reduce the amount of phosphorus from rural and urban sources reaching Lake Simcoe and south-eastern Georgian Bay and to restore the lakes' health. This indicator is used to provide information about the state of the Lake Simcoe and south-eastern Georgian Bay basin and Canadian environment. It is also used to assess progress towards implementing the 2016–2019 Federal Sustainable Development Strategy. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for the data sources and details on how the data were collected and how the indicator was calculated.
