Mashoor,
Of all the pilots I know who came to Canada from another country, learned to fly, then stayed and obtained permanent residency, they all either had a primary skill that Canada was actively looking for (as advertised on the Citizenship and Immigration website) or they had stayed long enough on an education visa that they genuinely began and maintained a relationship all the way through to marriage. I won't say that being a professional pilot is a not a required skill here in Canada. However, it is not a required skill that would earn you very many points when it came to doing your Immigration paperwork. You'll need to have something else to offer besides "low time pilot." Unfortunately for you, Canada has WAY too many homegrown low-time and high-time pilots out of work to offer that as a skill...including if you have a degree. No Canadian airline currently requires a degree for hiring purposes - many prefer you to have one, but its not yet a pre-requisite.
