if your family dont want to go with you now, later on from Canada you will have to sponsor them. which means you have to go through all paper work, showing funds in Canada, accommodation, job etc etc etc.
keep her on your application, claim points, once you get visa, you go first, then get them there for a week or 2, and send them back (if they dont want to stay) later its there choice to return to canada or loose their PR.
