How to get extra money from Osap as a dependent child

So I am first year student and the problem is that my father is terminally ill and isn’t working for sometime and I have been covering part of the bills by working full time but with university I can only work part time but they are not giving me enough money for my survival eat and commute.

Is there a way I can appeal or fill forms for to say I am paying my share and desperately need money even it is loan because of financial crisis
