The one subtle difference I've noticed between Canadian and American English is on school grades. American say "first grade" where as Canada say "grade one".

Toronto here, I think approximately I'd say first-sixth grade, and grade 7-12. Grade one just sounds wrong though.

Well, Toronto is ground zero for Americanization. First grade sounds super American to my ear, I'd never say it over grade one.

Odd, I grew up in Toronto and Grade 1 sounds fine to me.

in the US, people tend to say "first grade", but if you say "grade 1" nobody would blink, people say it all the time, teachers, administrators, etc.
