Former U.S. vice-president Al Gore has accused the oil industry of financially backing the Tories and their "ultra-conservative leader" to protect its stake in Alberta's lucrative oilsands. Canadians, Gore said, should vigilantly keep watch over prime minister-designate Stephen Harper because he has a pro-oil agenda and wants to pull out of the Kyoto accord -- an international agreement to combat climate change. "The election in Canada was partly about the tar sands projects in Alberta," Gore said Wednesday while attending the Sundance Film Festival in Utah.
