On the show tonight: Gregor Robertson is the centre-left mayor of Vancouver. His main commitment? Making Vancouver the greenest city in the world. And Gregor has a long track record on being proactive on the environment - he was an organic farmer, ran an organic juice business, and has a strong love for riding his bike to work, even in the rain. Gregor heads up the Big City Mayors' Caucus and George wanted to know what his relationship is like with the mayor of Canada's largest city - Rob Ford.
Gregor Robertson: "[Rob Ford] obviously face unique challenges in Toronto, and Canadian cities are great cities. If you compare us to the rest of the world, a lot of great things are happening in Canadian cities. We do need more support from our provincial and federal governments. They haven't really cottoned on to the fact that the rest of the world is investing in their cities, and put their focus there, and that cities are kind of driving the pace."
