Canadian here. It really depends on if it’s a cultural use or something the government might have an influence on through legislation. They can force industries to label packages in metric, but they can’t force grandma to change her manually-transcribed recipes. The other big influence is obviously our neighbours to the south. A lot of industries haven’t switched over there, and we get their products. Main culprit here would be the construction industry, lumber and hardware is all in US customary units and I hate it.
