Are swimmable cities possible in Canada?

Natural bodies of water are embedded in many Canadian cities, but are we taking full advantage of them? We speak with Neil Egsgard, President of the Alberta Surfing Association, about a proposed redevelopment at Calgary's Bow River, and Larissa Holman, Director of Science and Policy with Ottawa Riverkeepers, about the importance of swimmable waters in our cities.  And Ian Young, an associate professor at Toronto Metropolitan University, about what municipalities have been getting right when it comes to urban beaches.
