Watching the National weather on CBC news I see that Norway House in Manitoba is included. A generaly area with a population of 6000. Which would actually place it in the top ten of Manitoba cities, but it is not officially in the top twenty largest cities and towns in Manitoba, according to Wiki.

I suppose they have to rotate the cities they show, but I'll be watching to see the towns they show next.
