Yes backlogs can matter. If you have a large amount of backlogs there can be concerns that you will not be a student who can complete their studies in Canada. For competitive programs schools will look at how many backlogs you have. Not discouraging OP from applying. Just pointing out that they do factor into some decision making.I think the agent is misguiding you here based on your backlogs. I had the same thing happen to me. Backlogs do not matter. But your CGPA is what matters. Try some other courses relevant to your field at a good college like George brown.
