I don't know what your beef is with
@k.h.p. , but what he is stating is facts, most of the reputed colleges accept admissions from November of last year, so most of the popular courses will already be filled, they are either closed or on waitlist.
If PGWP is your end goal, then you can study in any college that is willing to accept you, we are not trying to shame you for going to such a program in such a college. We are just stating the facts that many private colleges offer substandard tuition, and charge as much as the higher quality public colleges. Private colleges are always willing to take advantage of such students and will give them an offer letter without question on payment of the deposit/fees.
Ultimately, it's your life and your money (or your family's money). If your aim is to study then most of us here in the forum would advise you to look for a public college that will accept your marks or do a short program in your home country and apply with that, since your current degree marks are not good.
If your aim is to use the study permit and get a PR with a PGWP, then you are more than welcome to apply in any college that you find. No one is going to stop you. We don't have a hidden agenda either by stopping people from entering Canada so we have less competition or the color of the flag in our profile.
