The Great Canadian Shoreline Cleanup is a conservation initiative of the Ocean Wise Conservation Association and WWF-Canada. The Shoreline Cleanupencourages people across Canada to remove shoreline litter to help create healthy waters for everyone, including the wildlife and communities that depend on them.

The Great Canadian Shoreline Cleanup is one of the largest direction action conservation programs in Canada and is a contributor to the International Coastal Cleanup. The Ocean Conservancy's International Coastal Cleanup is the world's largest volunteer effort for ocean health. It engages people to remove trash and debris from the world's beaches and waterways, identify the sources of debris, and change the behaviors that cause marine debris in the first place.

Volunteers and sponsors collect and catalogue litter which is then collected for analysis on sources of garbage that enter the ocean. For example, in 2011, 1,665 shoreline cleanup sites were claimed and a collective length of 3,144 km (1,954 mi) were cleaned, bringing in roughly 144 metric tonnes of garbage.
