I will repeat that this is not my area of expertise. I really want to be clear that I have to caveat my answer. I'll try to be limited to what I've seen.
My understanding is that many of the servers are in Canada. It's just that they're not owned by a fully Canadian-owned organization, which leaves the door open to potential risks, if ever situations were to happen geopolitically that would require them to be open.
I think much of the data is actually stored in Canada, but it's not owned by fully Canadian corporations. Again, this is not my area of expertise.
