Countries define urban spaces differently. Urban populations are actually difficult to define in most cities. In fact, Calgary is unusual in that it is a single municipality. The majority of big cities (contiguous urban areas) have multiple municipalities. This is the case for a "city" like Norfolk. The city itself may be quite small but it is part of a larger and contiguous urban area, called a municipal statistical area (MSA) that is much larger. That's the 1.67 million figure.
