Can you suggest me what i need to do to extend my study permit. (if yes, can i apply now or later)?
If you are enrolled in a program that is for two years, they will only give you a study visa for two years.
After all, it is a visa to study so they won't give you a study permit longer than the time you will be in school.
Before you graduate, you can apply for post graduate work permit. That's how I did it when I was a student in Halifax.
