That’s not the point. The point is that, at least in ontario, the Ontario College Graduate Certificate is a pathway for diploma students to access Graduate Studies (masters and phd). You don’t need a bachelor degree to be accepted in a Graduate Certificate program, and sometimes you don’t even need a college diploma but work experience will get you in. These programs are not Graduate Level. You can’t go from College Diploma to Masters, but if you do a College Graduate Certificate, which is a pathway, you can. Some shady colleges are using the term “graduate studies” to refer to this kind of program, but to be a graduate studies program you need at least a bachelor degree and these are open to diploma students.
