you don’t need to pay tuition to be approved of study visa. But you have to proof that you have sufficient fund to cover Atleast one year of your study and 1 year living expenses( stated on IRCC website) in Canada.
also make sure you pay any tuition deposit(usually $500-$3k depends on your DLI) you have with your DLI.
I believe you applied late for the visa. You are suppose to have more than 90days left before your learning start date from the time you applied for study permit. But due to Covid-19 there should be an exemption.
Best of luck
