Geesh, the cost of medical benefits alone in the US will probably cost you more then your paying for mortgage/rent in Canada..
I live In NJ, and the absolute bare minimum to the bone insurance for a single 35 year old is around $450.00 a month.. Throw in kids and your over $1000 easy.. Incidently, for $450 I have to pay the first $15,000 out of pocket.
