Well, let's see. Conservative politicians can appoint judges more to their liking, if they can get into power and stay there for a while. Provinces can use the not-withstanding clause to opt out of sections of the constitution if they've got the political guts to do it. And remind me exactly what the ammending formula for the constitution is: I seem to recall that no single small province can veto changes, although one large one could, but I may be mis-remembering.
I'm not optimistic about the chances for positive change in this country, but I'm not willing to throw in my hand just yet - my country deserves better than that. Your defeatist attitude certainly won't accomplish anything.
