The Globe and Mail reports the "Act On Climate Change" march included "representatives from First Nations, environmental activists and political groups" who are trying to convince politicians to ban oil sands extraction and prevent pipelines from being built to bring that oil to market.

Protesters dressed in red even marched in a formation that made a thermometer, meant to "send a message about climate change," the Globe and Mail reported. If it were a real thermometer it would have shown temperatures at a chilly 44 degrees Fahrenheit by 4 p.m. — the high for the day. Most of the day, however, temperatures were lower with some wind chill and high humidity.
