There is nothing to fear, i think you didn't read it properly.
The people mentioned in that article, they all loved that country and they didn't want to leave. One has stated its one of the best country in the world and he just moving bcoz of his home ties.
The problem they mentioned in the article was Canadians gives preference to their people first, instead of Immigrants in terms of wage, position etc. thats not bad. immigrants, they just move to Canada and start looking for work, but Canada employer they look for ppl with Canadian education, that y many immigrants are not getting a proper job with proper wage.
But for international student, it wll be easy for them as they will be having a Canadian education. So if you are going to study, settle and if you have gained practical skills in you field, required to work in Canada you don't have to worry.
Chill
They are far better than other country in terms of wage.
The thing is we never satisfy with anything, we want more and more.
