Well, I don't know. Not locking the door when you are away is a bit odd, and the insurance just won't pay if you are burglarized.. My understanding of the 'Canadian are not locking the door' thing was always about when you are at home. no?
I did not realize people locked their door when they're at home during the day.
I'm Canadian. I don't lock my door when I'm at home. I always assumed this question implied "when not at home", and I always answered that Canadians do lock their doors.
I don't think people in the US lock their doors when they're home during the day.
