Ha, ok, I guess my theory has holes in it... ya that is strange that the IONIQ comes with a cooling option in Norway. Only thing I can think is that either it isn't CSA approved, or they figure not enough people in Canada want it to make it an option.
Here's a useful comparison chart of the different EV battery warranties (created in Dec 2016 by Gary Exner, linked from GreenCarReports.com) Since it was created in 2016, it doesn't have the IONIQ on it http://images.hgmsites.net/lrg/battery-warranties-for-12-battery-electric-cars-sold-in-the-u-s-de...
I agree that most of the vehicle is the same. It might make sense to separate out the 'tech' section? Mind you, also the battery section? Maybe it makes sense to wait a while and see if the forum is mostly pure EV owners (which I imagine it will be since it's closely linked to other EV forums)
