Here are my (no1curr) thoughts:
I have never met anyone who alternated between French and English, despite living in both Western and Eastern Canada for extended periods of time.
I don’t know what Highway of Heroes is. (Maybe it came out after I left in 2007?)
I have never heard a Canadian say “maths”, unless maybe they were being pretentious/imitating a British person.
Canadians in most of the country tend to not freak out about snow. Snow is normal. You already have a shovel. It’s only here in Michigan that I’ve seen grocery stores completely sold out of milk, eggs, and butter as soon as a big snowfall is predicted.
Most of the country only/primarily sells milk in cartons/jugs. Ontario, you are weird.
