I have been to Toronto twice and enjoyed it. Also Ottawa, Montreal, Quebec, Victoria, and Vancouver.
If you are into scenery, might I suggest the Canadian Rockies and the Badlands (can be done in one trip). Also out east in Nova Scotia and the Gaspe Peninsula. I believe Newfoundland is well worth a visit (haven't made it there yet).
@antedeluvian I have also been to Toronto a couple of times and liked it. But Canadians (or at least Torontians) obviously pay as little attention to the idiots they elect as Aussies do. They say you get the politicians you deserve....and if you don't look closely at the guys first you are stuck with them.....
My family doctor retired about 18 months ago. He referred me to a much younger doctor at another practice who left town less than year later. I was then transferred to another doctor in the practice who also left for another postion, though still local. So now I'm on my third doctor in that practice, but have yet to meet him.
I did have physicals with the first two doctors before they left.
