It is the largest city in Northern Ontario in population, and the 20th largest metropolitan area in Canada. In land area, it is now the largest city in Ontario, the seventh largest municipality in Canada, and the largest municipality in English Canada legally designated as a city.
It is also the only city in Ontario which has two official names -- its name in French is Grand-Sudbury. Unlike designations such as Greater Toronto or Greater Montreal, the name "Greater Sudbury" refers to a single city, not a conurbation of independent municipalities. However, the name Sudbury, without its official modifiers, is still the more common name for the city in everyday usage.
