The only thing you can do is send your family to Canada while you stay with mother. They keep their PR and if you lose yours, you can appeal on humanitarian ground and if that doesn't work, your wife can sponsor you as her spouse to get PR again.
At first I'd like to thank you for your answer. If I'll open small business in Canada and I'll work in Israel for this business, it work? I want to send letter about my situation but I do not know were. Maybe to CIC,or another office.
