Calgary was the only city on a list of world heavyweights, including Toronto, New York, Boston and London, to receive an overall A grade, earning the city top spot in a prosperity report commissioned by the Toronto Board of Trade and delivered Tuesday.


The report, conducted by the Conference Board of Canada for the TBT, ranked 21 cities around the world on such indicators as: gross domestic product, immigrant population, crime rate and income growth.


In comparison with other Canadian cities, Calgary scored better than fourth-place Toronto, with Vancouver taking eighth spot, Quebec City 10th and Montreal 13th.


The information used to compile the rankings was drawn from up to the end of 2007, when the economic boom was at its height.
