Hi, Considering the current and future scope, pursuing below certifications are worth.
1) Cloud Computing (AWS, AZURE)
2) IT Security ( CISSP/ CEH)
3) DevOps
4) AI / Machine Learning
5) DBA
6) IT Networking
7) Mobile Dev.

You can go for college in which BCA programme is available and can apply for the same. As your marks seem too low, so you have to try for admission.

With a 3-year degree you are not eligible for Masters in Canada and if you do MS in India you won't be eligible to apply for a second Masters in Canada. So you can do PG Diploma from a SPP college and see if you can do your Masters. It will be difficult if you don't get good grades.

There is no proper course for ethical hacking. For this you need to do your graduation in B.Tech or BCA / B.Sc. (CS/IT). After doing this you may proceed forward towards ethical hacking.

There is no entrance exam for BCA, you only have to clear the interview round.

In today's era, according to me computer technology is more preferable than the business.
