Not true! Flavours existed, taste buds didn’t yet.

Canada’s official spelling is a unique mix as well as some of its own traits.

We add ‘u’ to colour, and centre is re, like British English. Or defence instead of defense. When we table bills it means to add them to the agenda, not pause them.

We use ‘z’ instead of ‘s’ in colourize, but call it ‘zed’. Its aluminum and ‘gynecology’, not aluminium and gynaecology.

We have our own words like ‘tuque’ instead of beanie.

Eh isnt just a joke, Canadian english has innovated English by adding a sentence final pragmatic particle (a word signifying the sentence is a question). Many languages have this while English needed a raised sound. Canadian added ‘eh’. Its similar to ‘ma’ in Chinese or ‘ne’ in Japanese. Mind you this last one never made it to my dissertation.

Not super related but I almost didnt get my PhD dissertation reviewed because while at LSE I insisted/demanded using neither British English nor American English, but Canadian English. In the end they caved and published it in my preferred spelling :).

I sort of hear you, but all other countries get around this because most new money has digital or computer vision trackers now. Making it in fact easy for vendors as their POS devices and software update for them.
