If the university accepts you without IELTS that means you will need to convince VO that your English is good (and they do not trust words but only official certificates), and even if VO issue you a SP without IELTS results, when you come to the university they will demand to take an English Placement test. If your marks are low they will accept you into program either after you study English for a year (that means you will need funds for tuition and living expenses for that year), or they could offer you to take English classes AND some academic classes- this also extends your stay in Canada, and you again will need more money.
