hey,

you did not mention in your question that you want to pursue for masters or bachelors course. see if you want to pursue bachelors than I will suggest you not to join because its really expensive. you also mention that your family financial condition is not good. after pursuing btech i n canada there is no surety that you can do job in canada and getting a scholarship is really difficult , it varies college to college. in india after btech freshers get job with 3-5lpa .

please think before taking any decision.
