I fail to see how the 27,000 (non-tax paying) Canadians in the UAE are being inconvenienced by the governments refusal to give the bully more landing rights in Canada. Currently there is enough capcity to move ALL of them to and from Canada every 9 weeks.
There simply isn't the demand for point to point traffic between Canada and Dubai to warrant more flights.
Personally I would love to see Canada close the airspace for a week and see what happens. Its a long way to most of North America if you can't come over Canada......
