Our citizen scientists gather crucial litter data.

Every Great Canadian Shoreline Cleanup participant is a citizen scientist. While our volunteers are out collecting litter, they record the number, weight and type of items they find onto our litter Data Card. We compile all that indispensable information in our national litter database and share it locally and internationally.

Notably, our citizen science data has been cited in scientific papers and has informed litter-related policy. Municipal single-use reduction strategies, provincial analysis on the impacts of foam docks and federal action to ban unnecessary single-use plastics have all been influenced by our shoreline cleanup data.
