I'm saying that, personally, I don't know, but I imagine the Department of Foreign Affairs and International Trade has an idea. There's also a publication entitled “Info Source”, which is a list of all government data bases. In my opinion, “Info Source” doesn't provide us with very useful information. It's simply a list of which we don't understand much.
I'm sure that someone in the federal government knows with whom we're exchanging personal information, country by country, but it's not me.
