Three of Canada's main political leaders took part in an aggressive debate on the economy Thursday evening in Calgary, Alberta.
The most controversial moment of the night came when Stephen Harper used the term "old stock Canadians" in a debate on refugee policy.
Mulcair and Trudeau accused Harper of "fear-mongering" over the refugee issue.
There was lots of arguing over whether Canada should run a deficit.
Harper admitted that things aren't exactly perfect. “I’ve never said things were great,” he said (twice), but then asked: In what country would you have rather been during the 2008 recession?
Trudeau was extra aggressive, and often set his sights on Mulcair. The Liberals and NDP are fighting over the sizable anti-Harper vote.
Moderator Walmsley asked the leaders how they'd deal with the fact that millennials are having a really hard time affording real estate.
Harper responded by saying that his government was providing tax cuts to make things easier on everyone. One of those cuts is for home renovation.
Mulcair mocked Harper for responding to skyrocketing housing prices with a tax credit: "How do you renovate a house you can't afford to buy in the first place?"
There was a big debate over whether Canadians should be paying more into the Canada Pension Plan.
Harper has repeatedly referred to increased CPP premiums as a tax increase. He argues that because they're money taken off of a worker's paycheck they amount to a tax hike.
Trudeau fired back: "Pensions are not taxes." Increased CPP contributions will ultimately lead to higher payouts.
Mulcair agreed, and said he sees increasing the amount Canadians pay into the national pension plan as "an investment," not a tax hike.
Mulcair was asked about how Canadians can trust the NDP considering they've never formed a federal government. He replied by invoking Tommy Douglas. A lot.
Being that the debate was set in oil country, and that falling oil prices are affecting Canada's economic health, the leaders got feisty when asked about energy and carbon taxing, too.
Trudeau said his plan is to work with provinces to get emissions down.
But Harper said that a carbon tax is essentially just more revenue for the government, and that the energy sector "needs a government that is on its side."
Mulcair accused Harper of relying entirely on the oil patch for his economic plan. "You put all your eggs in one basket and you dropped the basket," he said.
