Keynesian  economics are a left policy that Conservatives loudly amd largely reject. Because it was a minority government, Harper had to support the economy in the last recession - he was forced to by the Keynesian left.

I think the wage stagnation of  the last 20 years may be a large contributor to our very low growth during the Conservative years, teetering on depression. The Liberals are getting money circulating in the economy. The good times are a result of that.
