Rolling Stone magazine reports that opposition is building in Canada to a proposed “northern alternative” to the controversial Keystone XL oil pipeline. And the report says the disaster caused when Enbridge Energy’s 6B pipeline spilled “tar sands” crude into the Kalamazoo River in 2010 has only added to fears north of the border.

Rolling Stone’s Jeff Goodell says opposition to the proposed Canadian pipeline is especially strong among Native American tribes, known in Canada as the First Nations.

Enbridge is a major player in the push to build a pipeline linking the tar sands oil fields in Alberta with a proposed oil terminal in British Columbia. The government of Canadian Prime Minister Stephen Harper ramped up its support for the plan after the Obama administration blocked the Keystone XL project. It would have stretched from Alberta of the Gulf Coast.
