1 & 2 are colleges in Toronto, too many chinese there. Kids may not focus on study. And they are only college, the degree is not very popular. 3 is in halifax and 4 is in winnipeg. Personally I think 4 is better than 3. Regarding the weather, 4 is the worst as the city is very in land, very cold in the winter. 3 is in the east shore, beside the atlantic ocean, probably have the best weather
