Presently, in Canada, most airlines are welcoming foreign pilots with open arms.
Apparently, Canadian pilots aren't qualified for most vacancies due to the missing or specific type ratings. With B777 TR and time on type, Sunwing is waiting for your application with bated breath. You might try Canjet whilst you're at it. They're fond of talented pilots as well. Preferably, the non-Canadian kind.
Did I mention the Canadian Government will expedite your application should either of these carriers fancy your quals?
Worth a shot I should think.
