Live in Caretaker for elderly couple

My parents need a full time live in caretaker. They live in the Sundance area of Calgary and are 85 years old. Their home has a bedroom, bathroom and family room on the lower level that a caretaker could use. We need a kind, gentle caregiver with excellent communications skills and a good command of the English language. My parents like to go out for lunch and of course have doctor and other appointments they need to go to so it would be preferable if the caregiver had a drivers license. We would also like the caregiver to either take care of or assist my mother with grocery shopping. They prefer eating Western food so someone that could cook this type of food would be appreciated. Besides driving, personal care and meal preparation they need help with light housekeeping. We would prefer to hire someone who is able to work in Canada but if that does not work out, we are willing to sponsor someone. My parents are 85 years old. My father is handicapped. He had polio as a young man and now is suffering with post polio syndrome. He has to be moved with a lift from place to place. My mother is weak and has a bad heart. They are both mentally alert but my mom is forgetful at times. They would like a non smoker who is able to drive and cook western food.
