However the medicore distant degree and work experience you get in India doesn't help much. They value Canadian education more. That's why now they are planning to increase the points for Canadian education to 30. It's easy to get skilled jobs here. And, most of the direct PRs I see here are working in Call Centers.
This is just a hope. There's zero, z-e-r-o statements from official sources that stated the amount of extra points that would be given to students in Canada. If these points would even exist, to begin with. The only thing that was said is that they would consider ways to support international students to get PR. My bet is that we'll see more programs like the New Brunswick one, where students can apply for the PNP before the end of the course.
Then don't do mediocre courses. Good courses here help you get jobs. I studied in a program that had 50% PRs studying through OSAP to get skilled jobs. The ugly truth is most of the PRs who land here don't get skilled jobs and end up working in factories and call centers.
You're right. There's two ways of seeing this:
1 - The official data. In accordance with the StatCan's CENSUS 2015, there's a pretty reasonable gap between FSW and CECs (1yr after PR): 44k vs 70k. So, the data supports the idea that a Canadian diploma will get you higher salaries. That's one of the reasons why I plan on getting a college diploma once a land, as PR (I would NEVER pay the crazy amounts they ask for international students, no way). But, even considering that I plan on studying once I land, I do understand it's all about a piece of paper at the end of the course. Based on countless reviews I read and feedback I received from people that I know, the vast majority stated that the college courses didn't covered subjects in depth, most assignments were very superficial, and that they didn't learn anything new from what they already knew prior to the course. Maybe there are exceptions, there always is, but that's the view that I have after so many months of research within people from Brazil (my home country). But, in the end, canadian employers values that, so we need to play by the book.
2 - From my own experience. Based on the people that I know (Brazilians) that arrived in Canada as PR, I don't know a single one that is in a survival job after 1yr. Maybe this might not represent the whole newcomer situation, since I know there's some sort of prejudice against Asians, Africans and Indians, for example.
Finally, just to be clear: yes, getting a Canadian diploma helps. But, considering the time it takes for you to actually get that diploma, you'll probably meet these same salaries if you're properly qualified and have a good language proficiency.
