And here's a (kinda) scientific study of differences between Canadian, American, and Commonwealth English. https://geekdad.com/2013/12/55-canadianisms-1/
I know to call (what I call) the washroom, the "bathroom" when travelling in the USA to avoid funny looks, but some of these are surprising! The meaning of a "two-four" is universally understood in Canada ... you don't even have to specify what it is that you are speaking of.
To go out on the race track (for example), and "Give'er" ... everyone here knows what it means. Apparently, not Americans!
Item 40 in that study has been sanitized (and they mention this but don't give the real term). The real term that is used in place of "bugger" has four letters, the first one being F.
Question for the Americans. Do you know what a "double-double" is? All Canadians know what that is!
