withdrawing from the Commonwealth
Lets talk about it, "commonwealth", do you think Canada should continue to be ruled (symbolicly) by a English monarch? Since at least half of its population has not any English origin (unlike New Zealand or Australia) and do not identify themselves with Elizabeth II as queen (btw just my opinion, Canadian dollars are quite ugly, not because the queen is on it, but because it looks like monopoly bills). I guess you heard of QUebec independence movements, one first step would be to put out Canada from any English sovereignty (even symbolic) like Ireland did once, and that would reconciliate all the Canadians.
