Thousands of Canadians are expected to participate in the Great Canadian Shoreline Cleanup, running Sept. 15-23.

With an estimated 1.5-million tonnes of debris from the 2011 Japan tsunami possibly washing up on the West Coast and posing a threat to waterways and coastal areas, the public can make a difference. More than 42,000 Canadians have already registered to clean up nationwide.
