Federal NDP Leader Jagmeet Singh, also trying to mediate between two NDP premiers, wants the federal government to join B.C. in a Supreme Court reference to decide on jurisdictional issues. The federal Conservatives have long called for Trudeau to do more to get B.C. to drop its actions against the pipeline.
The Liberals say that all options are on the table, but insist that the pipeline will get built.
The prime minister has a lot to lose either way. But is destroying the oil and gas industry in Canada in the national interest?
