No British equivalent of the Prairies/Great Plains in North America. Not sure if a regional party on the right would emerge in the 25 or so rural Prairie ridings. Just hard to imagine Don Valley West and Souris-Moose Mountain having similar voting patterns.
I think some educated guesses can be made. The main cities have a Labour core but overall vote Conservative. The agricultural and oil dependent areas vote strongly Conservative (though the agricultural areas may have some Lib Dem history). The post-industrial areas may vote Labour (it’s unclear to me how much impact industries such as coal mining have on voting habits given the lack of obvious enduring NDP strength, can other posters expand on this?). The Indigenous areas are probably the hardest to work out. The strength of the NDP in these areas suggests Labour, but they’re the sort of group that either the Lib Dems or regionalist party could appeal to (and there would probably be stark geographic divisions).
