*Americans pretending to be Canadian call for Carney to use American spellings.

It’s a bullshit argument from a linguistic standpoint, not just political.

Like imperial/metric and fahrenheit/celsius, we just use the z vs s variably. Some people even switch between spellings for some words. I’m not sure there are even idiomatic or de facto rules about usage, since it seems to be an area of uncertainty for many.

Is there a list comparing some key words in British / American / Canadian spelling? I assumed the Canadians basically used American English, maybe with some accent, but this suggests there is a real Canadian English, implying differences to other variants.
