Welcome to the first Canadian Environmental Challenge hosted by the Green Grouch. The Green Grouch is a very grouchy (but funny) character that wants to help us all become better stewards of the environment. He's challenging the largest cities in Canada to see which one is the most environmentally friendly. Participation will only take about one minute of your time once per week (weekly checklist). With one click, you can compare fifty Canadian cities! If your city is not on our list, please login representing the nearest city.
