1 year tuition fee + CAD $10,000. If you want to be on the safer side, try exceeding the minimum amount they are expecting to see on your bank statement.
For example, your tuition fee for a year costs $15,000. Add $10,000 to that, and that will sum up to $25,000. $25,000 is the MINIMUM amount they need to see on your bank account. Sometimes, exceeding the minimum amount will increase your chances, but of course, showing them where you have sourced out your funds will make your case stronger. Do not forget to include any loan letter (if you have), salary certificates of your parents and yours (if you're working), and other documents. If you have relatives in Canada who will be supporting you during your studies, it also ideal to ask a letter from them indicating all the things they will support you with.
Hope this helps.
