Come out to lend a hand in cleaning up the waste that washes up on the shores of Lake Ontario and the Rouge River to make your national urban park a cleaner place!

We are co-hosting this event in collaboration with WWF-Canada and Ocean Wise during World Cleanup Day, the International Coastal Cleanup, and World Rivers Day weekend. 9 am-1 pm. Free. Pre-register.
