Onvergence between the Liberal Party of Canada and the Progressive-Conservative of Canada

The main hypothesis of this paper is that the Liberal Paty of Canada and the Progressive Conservative PArty of Canada, both enact the same policies and that it doesnt really matter who is in power, since Canadian poltics has a lot of convergence. I began with what I have sent however, i need more specific policies that where created by both parties while in power. this paper has to demonstrate that both parties are really similar centrist parties. My sourcing is not correct.
