This week, the Liberals introduced their new “Building Canada Strong Act," which is generating controversy over its proposed changes to environmental reviews and workers' ability to strike. Environmental Defence’s Julia Levin explains her worries that the plan will “steamroll” nature and communities, while Transport Minister Steven MacKinnon argues the bill will respect labour rights and environmental concerns, while getting the country building faster.

Plus, heads turned when Prime Minister Mark Carney told The New York Times that Canada had prepared for the "extreme tail risk” of U.S. military action. The NYT’s Ottawa bureau chief Matina Stevis-Gridneff and CBC’s senior defence correspondent Murray Brewster discuss whether this is a cause for alarm, or run of the mill.

And, B.C. Premier David Eby called a snap election this week, but his main opponents — the B.C. Conservatives — are officially leaderless after months of infighting. Former NDP cabinet minister Nathan Cullen and Conservative strategist Rachael Segal discuss whether Eby could face the voters' wrath, and how big a fight the B.C. Conservatives can mount on short notice.
