It's always worth looking at the past to find reason in the future.
Some of us licenced Canadian citizens "with" a B737 type rating may simply have no desire to work with/for certain
individuals who seem to constantly show up at places like Sunwing, Royal, Zoom, Canjet, etc., who are nothing more than 'born again' carriers anyway, with different names and paint jobs. Who amongst us believes that Canadian Labour officials have even the slightest clue about aviation in this country and who's available to take a 737 job? Isn't it easier to listen to the carrier's HR department than actually get up off your lazy arse and check it out?
I'm sure Sunwing needs qualified and experienced pilots. But, whomever they look for to hire, he/she should at least be Canadian!
Bottom line. Who cares? The future of aviation in Canada is overseas.
Last one out turn off the lights.

best of luck to you all!
happily and gainfully employed,
Willie
