A report commiss­ioned by the Toronto Board of Trade on global urban prosperity has given Calgary the top mark.

Calgary was awarded an “A” while Toronto tied for fourth with a “C” — the same grade given to cities such as Boston, London and New York.

Vancouver came in eighth and Quebec City placed 10th — both with an overall grade of “C.”

The Conference Board of Canada study, which is based on information gathered before the economic downturn, says Toronto is an attractive, livable city, but is languishing economically and is not very competitive.
