Hi,
Canada is not only a good place to build hours, but is a great place to gain EXPERIENCE. The way I understand it the only way to "build" time in the u.s. is to instruct. In Canada, there are more options, floats/bush, charter with small twins into short gravel strips, or straight into the right seat of a King Air is also possible.
I agree with the last poster in that there are alot of under qualified pilots out there trying to get a job but the strong will make it and the rest will peter off eventually.
Some thing that may work in you favor is that Canada seems to fuk over its citizens all the time, unlike the U.S., we WILL let outsiders in to take a job when there is a qualified Canadian looking. There are a ton of Aussies and keewies on the radio everywhere i go. Good luck, you cant go wrong if you get a job here, its some of the most challenging flying out there.
BTW, to the original poster. The NWT is really booming right now, there are companies expanding like crazy.
