OTTAWA — A look at key developments Sunday on the campaign trail:
The Liberals and Conservatives both held news conferences attacking the New Democrats' campaign promises. Liberal MP and former economist John McCallum said the shortfall between Mulcair's promises and his pledge to balance the budget amounted to $28 billion over four years. Tory cabinet minister Jason Kenney pegged the hole at a minimum of $8-billion in the first year of an NDP government. He said an NDP government would mean reckless spending and massive tax hikes that Canadians cannot afford.
NDP Tom Mulcair was the only major party leader on the campaign trail Sunday, attending a rally in Halifax. He dismissed the Liberal and Conservative attacks on his platform as a sign of desperation by rivals trying to blunt the NDP's momentum. Most recent polls suggest the New Democrats are in the lead.
