Hello Gagan :)

There are few popular courses in Canada for post graduation. These are as follows:

1. Science and Engineering
2. Forensic Science (Non-medical)
3. Information technology
4. Health care
5. Hospitality Management
6. Business Management

Amongst these, the first 3 might be more suited to you.

Now, requirements are:

1. Minimum of 50% in Bachelor's degree with not more than 2 backlogs per year.

2. Minimum 6 bands overall in the IELTS exam.

Another option for you: you could learn some vocational skills of your field and apply for a job.

Hope this helps.
All the best.
