@silverstone,
proof of fund does not mean proof that you have made any initial payment. It only means proof that you will be able to pay all your tuition and living expenses when you get to Canada. They Embassy needs the summation of all your expenses including tuition,accomodation,food etc and calculate it all against the financial evidence you have produced to be able to see if you meet the financial obligation for visa approval.
Normally,if u apply to stouffville college,One year academic admission will be written on ur unconditional admission letter and you need to show a proof of financial capability for the whole year. When you get to Canada,you may need to extend your visa. What matters now is to get your visa first,then other things will follow.
ciao
