Prime Minister Mark Carney and Alberta Premier Danielle Smith have signed an agreement that sets the framework for building a new pipeline, carrying bitumen to the west coast. The deal commits to simultaneously making Canada a “global energy superpower” and reducing greenhouse gas emissions to net zero by 2050. Indigenous co-ownership is a requirement for development, as is consultation with British Columbia. In response, Liberal minister Steven Guilbeault, a former environment minister and longstanding environmentalist, has resigned from cabinet. Campbell Clark, The Globe’s chief political writer, joins the show to explain what’s in the deal, the politics involved and how likely the pipeline is to get built.
