I would have preferred to have permanent residence visa in USA rather than in Canada, and I have heard that if somebody adopts me as a child or something else, I can get the permanent visa. But if you adopt me as your old child, probably the visa department will laugh, that what you will do with an old child who is going to die very soon. But, if there is possibility to adopt me as old father, then you can try for it. If there is any law that you can adopt any old man as your father, and take care of him, then you can inquire from the Los Angeles immigration department and try for it.
