Please help me!Hoping to here positive feedback

Hello, this is my 1st post, so let me start by introducing myself. My name's Manuel and I want to go to school in Toronto but the tuition fee doubles for international students. My "situation" is that as child I legally lived in Canada for 4 years and just a few months away from the government granting us our Canadian citizenship's the civil war afflicting my home country ended and my parents decided to go back ASAP! I was only 10 at the moment so it was completely out of my hands. So here comes my question/doubt: is there any type of "program" or anything of the sort that I would have access to, or is there an immigration process of the many options that the Canadian government offers that would apply to my situation? Please keep in mind that I do not seek a citizenship or financial aid, just for some financial relief. I'm asking for some guidance for the best option from someone that knows about these matters.

thank you.
