Our national affairs panel breaks down today's big vote in the House of Commons: With the Conservatives, Bloc Quebecois and NDP all finding reasons to vote it down, is there a risk this government falls and the country is thrust into another election? Plus, the Prime Minister will hold a call with Canada's premiers who are pressing for more details about the halted Canada-U.S. trade negotiations. We sift through it all with CBC's Chief Political Correspondent Rosemary Barton, Stephanie Levitz of the Globe and Mail and Ryan Tumilty of the Toronto Star.
