If a candidate decides to study in Canada, he will gain points in three areas-language, education, work experience, and additional points if he is young. Education in Canada can give valuable points for various immigration streams such as Express Entry or PNP streams.
Students are also allowed to work up to 20 hours per week while pursuing their course which helps them gain valuable Canadian work experience and add points to their CRS score.
Studying in Canada will help you get familiar with the culture, people, and language (English/French) which will help your social integration once you become a permanent resident.
