Do you speak french? as montreal is on the French side of Canada (I hope or i'm going to look really stupid, lol). And I think if your visa is there you need to pass a french and english test although this could be just rumour, best to check with someone there.
My wife and I are looking at Toronto all the way round to Hamilton as it appears on the net to be only 8-10 hours flight back to blighty if we need to get back in an emergency (Dad has a heart condition). Also I have a friend from ON and she says that it is like a friendly London, lol but we are going to go on holiday before we make a move out there and see for ourselves. I've already been to Alberta and visited BC while I was there. I loved edmonton, calgary and vancover but I want to see what it is like in Toronto before I make up my mind.
