Thanks everyone for your suggestions.  Overall it looks like taxes are high in Canada than US but social benefit including health insurance are better in Canada.  Can someone share their experience on cost of living, like car insurance, rent etc on cities like Toronto or Vancover.  When I was at Boston, I used to pay $1,400 for 2 bedroom appt and about $70 on car insurance.  Food and other stuff are prettymuch same all over the US. 

Thanks.
