VANCOUVER, British Columbia (AP) — Members of Canada’s First Nations and their allies are mounting last-ditch challenges to two massive fossil fuel pipelines that already are under construction and have strong government backing. In campaigns reminiscent of the Standing Rock protests in the U.S. Great Plains, the anti-pipeline actions in Canada’s far West feature acts of civil disobedience including blockading roads and construction sites, and coordinated campaigns against banks and underwriters that are financing the pipelines. Dozens of protesters have been arrested. The activists’ targets are the Coastal GasLink pipeline to carry fracked gas from northeastern British Columbia to a Pacific port for export to Asia; and the Trans Mountain pipeline from Alberta’s tar sands to near Vancouver.
