Trudeau appealed to voters in Western Canada, aiming first to convince Albertans to vote Liberal after years of his party failing to capture any seats in the province.

"The other guys want to take us back to the days where they could get their hands on as much money as possible and spend it on bureaucracy and special interests. We have been building a Canada over the past few years that they do not like," he said.
