All of the Canadian youtubers that I watch pronounce the letter z as “zi”, as is done in the United States. However, I have read online that it is more common for Canadians to pronounce it as “zed”, as is done in the United Kingdom. Is this a regional thing? How do you pronounce the letter z?


As a mumbling Canadian, I always say Zed to avoid confusion with the letter C.
Regarding your point about Canadian YouTubers, I’m guessing their audience is overwhelmingly American, so they purposely say Z the American way. It also extends to money, temperature and other units. I hear Canadian YouTubers give prices in USD and temperature in F.
This Canadian youtuber doesn’t.
I’m Canadian, and I pronounce things the proper Canadian way.
When mentioning measurements or temperature, I use metric, and if I also happen to translate to imperial, I joke that it is a courtesy translation for the 3 countries in the world still stuck in the obsolete units.
In my experience, I find it’s usually g/z that tends to get the most easily confused when pronouncing as “zee,” guessing because both are voiced consonants. One of those cases where I have to request phonetic alphabet spelling if call/chat quality is too low to tell.
That makes sense. I assume it’s that, as well as perhaps consuming a lot of American media. I’ve noticed a lot of non-Americans sometimes using USD.
They export American exceptionalism as a default attitude.
And, after a century or more, it has taken hold far more than it has any right to.
I hope the increasing boycott of all things American that Trump has caused will start to reverse somehow that. But it will take a long time to undo - that shit is pervasive.
