Ontario

Are you talking about Fleming college ,Ontario, Canada? If yes, then it's hard. Actually, the colleges are not that reputed in Canada. Fee maybe less and they won't provide any placement assistance. I know some people who graduated from Fleming college. They are struggling to get a job.
This is one side of the coin.
Another side, everything is based on your luck and if you have contacts there in Canada like your family relatives is there and if they help you to get a job, then it will be somewhat easy otherwise you will struggle.

MS in CSE is a very competitive course, and all the colleges/universities you have mentioned are under SPP. SPP courses get high number of applications, so it becomes even more competitive.

GRE scores might prove to be important in your case.

Yes, you have decent scores in IELTS which are more than enough to get admission in these institutions but your academic scores will also matter.
