“Zee” is getting more popular especially with gen Z (unintended) who were raised with more widespread access to American media, social or otherwise. Like many Commonwealth countries, most of Canada uses “zed”, however.
Canada is unusual in many ways, I’d say hehe. We never separated from the British like the colonies did, so the languages (quebecois French, too!) have kept a lot of British influences. About 2/3 of its relatively small population of 41 million lives in the first 100km north of the US border - an individual in British-Columbia is 8000km+ and 5-6 time zones away from someone in the Atlantic provinces. We’re similar to the US in how different every province can be from one another, I think.
