It's an interesting situation. I'm assuming you're talking about variety registration. Theoretically, when you register a variety in Canada, it's supposed to be a national registration. Provinces again—Ontario is a big one; Quebec is a big one—have big concerns around things like fusarium, as Alberta does, and they actually restrict registrations. If I develop a variety in Saskatchewan and register it through the western committee, theoretically it's supposed to have a national registration but very, very seldom does it. What that means is that seed can't be sold in those provinces where it's not registered.
