“The tarsands are the roadblock to Canada signing onto a meaningful target,” said Eriel Tchekwie Deranger, a climate-change activist and member of the Athabasca Chipewyan First Nation in Alberta. The point is that the tarsands are a bad bad bad bad story, and it's on Canada's head. The world on the one hand is looking to Canada to fill in the gap between oil demand and oil production with those tar sands. Environmentalists would prefer that oil simply go away, and tarsands will act to keep the oil business alive, plus the tarsands are just a nasty way of producing oil.
