We use English in this house, although the wifey spews the odd word in Anishinaabemowin now & then. I have a few choice words in Gaeilge and a couple others, too. I call Americans 'Yanks", too. lol There isn't a lot of difference between Canadian words and American words, though. Mostly localised differences. Food's pretty much the same, too. We say "roof" as in "goof" rather than "roof" as in "ruff", "creek" as in "peek" rather than "creek" as in "crick".
Measurements are in metric.
Hobbies are stuff like gardening, woodworking, running, hiking, camping, boating, etc. Much the same as in the States, I'm sure.
