Yes, clearly, our democracy has worked well.
From my experience with the Law Commission of Canada and the Ontario referendum, I would say that our system could be more effective, especially in terms of including representatives and the varying views of the electorate.
There is no doubt that Canada enjoys a successful democracy, but the system does have its problems or flaws, shall we say. Fixing them would simply involve reforming the electoral process to provide for more proportional representation. That is not to say Canada's system isn't working.
