Share your ideas: Assessing phosphorus targets for Lake Ontario
Current status: Closed
We are seeking your comments on an assessment of Lake Ontario’s nutrient targets under the Canada–U.S. Great Lakes Water Quality Agreement. Input received will be considered in the development of a final recommendation on targets for Lake Ontario.
Nutrients like phosphorus are essential to the growth of aquatic plants and algae. Too much phosphorus leads to excessive growth of toxic and nuisance algae, yet too little phosphorus can affect aquatic food webs. Nutrient-related impacts affect our health, environment, economy and well-being. Nutrient targets are a key tool that guide planning and action to achieve environmental results.
In 2020, Canada and the United States established an expert task team to review the interim nutrient targets for Lake Ontario and determine whether they should be revised. Based on the findings of its assessment, the task team does not recommend revising the targets at this time. For more information, visit the preventing toxic and nuisance algae page of Canada.ca.
