About Blue Sea

Coldest Day of the Year is operated by Blue Sea Foundation (formerly known as Blue Sea Philanthropy). Blue Sea believes in the power of charities to make the world better. Our vision is to see a more generous world where charities thrive.

We are a registered charity with the CRA, but you may know us better from our three other national events in support of social service charities in Canada:
