As you're aware, corporations can be incorporated federally or provincially. Provinces are responsible for partnerships of all kinds. There are other business arrangements as well, and trusts. That's also provincial.
My understanding, from the announcement made by the finance ministers in December, is that all the provinces have agreed to make changes to their corporate law statute to require the disclosure of beneficial ownership information. It's an excellent beginning.
In terms of the creation of registries, because of federal-provincial responsibilities, my proposed solution—I mean you can't get away from those responsibilities—would be that there be co-operation to set up a single portal and search engine that could pull information from all of the registries.
By the way, these registries already exist. They're called “business registries” or “corporate registries”. They don't currently contain beneficial ownership information, but they could. They could be amended.
Undoubtedly, it will be a bit of a patchwork over time, but presumably with the commitment, which exists right now, we'll get there. It would be most convenient for businesses to have one search engine that can pull all of the data from all of the registries at once.
