Support for minority rights, the labour movement, and the continuation and expansion of the welfare state are the key elements of leftism. Liberals in Canada are an odd mix of leftism and traditional liberalism, but the NDP are not really liberals at all. Their staunch opposition to free trade is a big part of that (I have no doubt the Liberals will pass TPP, awful copyright provisions included). They also proposed expanding universal health care to cover drugs, which is huge.
It seems as if the discussion of left vs. right in Canada has devolved to fiscal liberal vs. fiscal Keynsian, which is to my mind absolutely bizarre.
As a key practical example of the difference between the two parties, the Liberals would never filibuster back to work legislation.
YEP!
