Wow, I thought only mature applicants were considered as criminals by VO who intend to illegally stay in Canada. Interesting to see they feel the same now about younger applicants as well. Honestly, If you have shown your fathers property who will support you then I really don't know what else they want. At your age they don't expect you to own properties and liquid cash. This VO has not even explained it properly. I strongly believe in AI technology and feel that is the future. I cant tell why VO does not feel that way maybe they are still old school and don't understand what it means.
In summary, your best bet is to go through some consultant, they know how to twist words and facts and make your profile look good which is exactly what VO wants.
