CDN Vs USA and CX
 

Sounds like many believe that it is harder for USA pilots at CX, does this apply to Canadians as well. Just curious I know little about this.

I don't know if there is any truth to the rumour that it is any more difficult for particular nationalities. What I can tell you is that it is not "easy" for any candidate - no matter what nationality.

However, to answer your question and set your mind at ease:
During my 2nd interview there were 9 candidates (including myself). 6 of us were Canadian. 5 of us out of the group were successful - all of us Canadian.

Hopefully that gives you some comfort. Good Luck.
