I may immigrate to Canada in a few months from Bay Area, USA. I have a 4 year old kid. I have heard that schools in Canada are very good, but looks like as in Bay Area, USA there is some kind of performance ranking/rating among schools in Canada too. One of our places to settle is in BC Province's Greater Vancouver area for work reasons. In one website I saw some schools in BC rated from 1 to 10, with the 10 rated schools considered the best, and saw many schools with 4, 5 etc rating. Is this rating a big concern or in general all schools in BC provide quality education even if rating not that great?
