When I refer to Newmarket I kinda mean Newmarket, Aurora, Bradford, East Gwillimbury, Stoufville etc. I loved all of York region and it was a very nice municipality to grow up in compared to some of the places I've been!
905 to 519 transition is what I did Rob. I like both places for their own strengths and weaknesses. Living in the country means I don't have access to high speed internet which I really would enjoy, but you are right about the clean air, the affordable homes, and I enjoy the lifestyle that comes along with being out here!
