Finance Minister Bill Morneau introduced his budget Tuesday just before 4 p.m. EST, but his customary budget speech to the House of Commons was delayed by an hour after a series of procedural manoeuvres by the Conservatives. When Morneau finally started speaking, Tory MPs drowned out most of his address by stomping and shouting. The Tories were protesting the justice committee's decision earlier in the day to pull the plug on its probe of the SNC-Lavalin affair.
