If you wish to go abroad for the courses, then you need to clear all your backlogs and get the Degree certificate/ provisional degree certificate and with that only you can take admission in the colleges present in canada for different Masters courses. Without clearing, the backlogs, it won't be possible for you to do a course on the computer science/computer application there.

I hope this helps. Wish you a great day!
