NAV Canada are being 'pushed' to employ Canadians in ATC
Even though I was "lucky" enough to come through the experience controller route...I have no problem with companies hiring local.
If Nav Canada is able to recruit enough through local means then that is better for them and the job market in Canada (and more cost effective to start with).
Whilst frustrating for experienced ATCOs now looking to move for Canada...it can't really be argued that they should take precedence over local...unless the company is having problems with getting locals checked out on their sectors.
you can take someone off the streets and make them ATCO's in a few months
Even the experienced guys have to relearn a LOT of stuff...new airspace, new procedures, new accents etc etc. Although quicker than a newbie..it still takes afew months till checkout.
