U.S. retailers' oilsands boycott sparks Calgary anger

CALGARY - Oilsands operations in Alberta suffered another public relations blow after two major U.S. retailers announced they were shunning bitumen-derived fuels in favour of greener gasoline for their fleets.

That has irate Canadians calling on people to shun them back, including one Calgarian who says he'll fight the bitumen ban with his wallet.

Also on Wednesday, Sierra Club Canada filed a complaint with Advertising Standards Canada alleging Shell Canada and Canwest violated the Canadian Code of Advertising Standards by not clearly marking several full-page Shell advertisements as ads.

The six-part series on climate change running in Canwest publications such as the Calgary Herald lacked proper disclaimers, the environmental organization said.
