Where are you originally from? what country did you file your case in? How many countries have you visited so far in your life time?
1. You only need to show funds for one year's expenses. Normally that range varies from school to school. However, it falls somewhere between this range of $30,000-$32000. Showing extra money out of this range is a plus point. Let's say, showing $40,000 would be great.
2. Not every school has this requirement of accepting first semester fee in advance in Canada. So fulfilling this requirement won't alone help your case.
You need to take care of your travel history reason, imho. See, if you can show more money in your bank account.
That's all what I can think of as a layperson.
