now is definitely a better time than a few years ago to be looking for a rotary job in canada, but i wouldn't say it is easy, especially with 150 hours. the schools here are still putting out enough 100 hour pilots to fill the vacancies that are out there. your chances of being hired would be affected by what your 150 hours consists of...turbine and mountain time would definitely help your chances. you would also probably have to expect to work on the ground for a period of time before a company would get you flying.
hopefully this helps a bit?
