Q: What would make a load unapproved for Canada?
A: Every single load has to be individually approved in Canada. ie, not just the manufacturer. That is why when a new 'caliber' comes out, there is a delay getting it into Canada while the USA has it for months. So, unless someone takes it upon themselves to apply for it, it cannot come into Canada commercially.
