What we think of as traditional Canadian fiscal conservatism is more correctly prudent fiscal liberalism.

Oh 100%: Justin Trudeau's policies are either taken directly from the Con party (Carbon Tax credits, etc), or are directly in line with their values. The Con party has voted in favour/alongside the Liberal party in something like 95% of all votes taken since Trudeau came to power.

They just don't like him. That's fine, I don't either. The issue is that, also as you've stated, they keep inventing this idea that 'fiscal conservatism' A) has worked in the past, and B) will work now. They shuffle past the fact that when they were at their best they were Neoliberals.
