Hellu ^^

I'm pretty new here and I plan on sending a fan letter to Victor Garber (actor). There is fan mail address to him in this database, and tge address is in Canada. But I've also checked another celebrity-address-database, Contact a Celebrity, which has an address in the U.S.(submitted in 2008).
I asked on the "Is This Address Still Up-To-Date?"- board here and that the Canadian address was up-to-date. But I can't help to find it a bit strange, since he doesn't live in Canada.

The question is, which one do I choose?
And does Contact a Celebrity and Fanmail.biz collaborate to get the right addresses?

Thanks in advice
