Erik,
I was writing some more on it, by then u had posted. Sorry for an incomplete posting, Bro.
On your query, plz note that it is always good to have some Canadian expo, even out of Canada. That 'increases' your chances, absolutely. More than the US degree, that u worked for a Canadian employer shall definitely help.
However, many other factors also matter in our job foray, whether in Canada or elsewhere over the entire Globe... the issues pretty much remain the same, if u know what I mean.
BTW: How much that overseas Canadian exposure shall take u along is not foreseeable, But it will help a lot, that's for sure.
Qorax.
