Does Nunavut get its own area code? Area code boundaries are a pretty good
proxy for economic activity, but quantization error creeps in (at least in the
US and Canada) because they're limited to legacy sub-national political
boundaries. As far as cultural boundaries go, 503/541 and 703/540 spring to
mind... (Are 514 and 819 francophone? or just 418?)
