Wife can apply for OWP or visitor visa and daughter can apply for visitor visa. Whether they are gonna get their visa or not, it`s another issue. They are your ties to your home country so if you all move to Canada, you will need a much much stronger SOP and it becomes extremely hard to explain. Your daughter may not be able to stay in Canada throughout the entire trip so need to take that into consideration as well.
As long as you are aware that you need to take a degree which show strong career progression and align with your previous education and experiences, you will understand that the main problem here is for you to get admitted into a public well-known university. And that admission takes time and efforts. I know it`s hard cause you sound so lost, but you need to identity the priority and make time for it.
Good luck.
