Hi Ronak,
You can apply for a student visa only if you have the admission offer from any of the universities located in these countries. Check for admission requirements and prepare firstly. If you meet the entry requirements, there is no reason why a university will not accept you. So instead of worrying about the visa process now, you should decide what to study and research on the entry requirements. Canada is a home to famous universities like McGill University, University of Alberta, University of Toronto, University of British Columbia etc.
