Federal election campaign underway with leaders in Ontario, Quebec and B.C.

Justin Trudeau began his bid for re-election Wednesday by framing the next 40 day campaign as a time for Canadians to make a choice: whether they want more of his sunny ways or a return to the gloomier days he says are characteristic of life under a Conservative government. But clouding over his optimism was the SNC-Lavalin scandal, given fresh life by a Globe and Mail report that the RCMP's investigation into potential obstruction of justice in the matter has been limited by the shroud of cabinet confidence. Moments after emerging from Rideau Hall, where he asked Gov. Gen. Julie Payette to dissolve Parliament, Trudeau faced a barrage of fresh questions on the affair.
