Income inequality, known for its corrosive effects on health, happiness and community ties, is much worse in some large Canadian cities than others, according to a new analysis of Statistics Canada data.

While Vancouver, Toronto and Calgary have significant levels of household income inequality, the gaps between higher- and lower-earning residents in Brampton, Ont., Surrey, B.C., and Winnipeg are much less pronounced, according to the ranking assembled by the Local News Data Hub at Toronto Metropolitan University.
