What Number 2 said........
I e-mailed Navcanada 18 months or so ago and did get a reply. The experienced controller program is dead but they implied that they would look favourably on an experienced controller applying through the normal channels, assuming that said controller had the correct qualifications to live in Canada & be a permanent resident (landed immigrant).
You would, however, have to retrain fully, going through their college (which i believe is in Winnipeg ACC now - someone correct me if i'm wrong) - which would be the equivalent of doing CATC all over again. Yay!!
Any help?
