I wanted to move to California about ten years ago. My career was headed that way as I was working with some of production people for The Rolling Stones at the time and they were in Los Angeles. My wife wasn't so keen. She was finishing her fellowship in Gyn/Onc and had some offers to go south but they all made her nervous for some reason.
So, as with all marriages, we compromised and stayed in Canada.
Still, I have vivid memories of one interview in Miami where they set us up with a real-estate agent. She showed us some of the possible places we could live and one was a condo on the beach. 3,500 sq ft. with windows on three sides and a private elevator BUT (and this was the uber-cool thing for me) you went down to the lobby and walked out onto the beach! You just can't get that in Canada!
To this day I joke with her when the first snow falls - "Do you remember that condo on Miami beach? We could have been living there BUT NOOOOO!!!!" : )
OHIP is different for Gyn/Oncs now. They cooked up an APP which is basically a salary and not fee for service. In the process their salary increased by a factor of 2.5. It has it's own issues but many of them were moving to the US for dollars and they had to stop that somehow. Now I think most are paid more in Canada than the US - at least the ones in academic centers.
