Matt84 - Canadian operators overseas are still Canadian. They fly Canadian registered aircraft on a Canadian operating certificate and their employees pay Canadian taxes, and therefore, they must have the right to work in Canada.
Examples - Voyageur in Africa/Afghanistan, Execaire in Las Palmas/Mauritania, Summit in Africa (not sure if this is still going on), Trans Capital in Africa/Afghanistan, various Canadian airborne survey companies working overseas... ALL employ pilots with the right to work in Canada.
I have heard that CHC occasionally hires helicopter pilots that don't have Canadian work permits, but those are generally either higher time, ex-military guys are nationals of the country in which CHC just happens to have a contract (i.e. I believe they do this in Thailand) as part of the agreement with the local government. There may be other companies like this but I haven't heard of them.
