You definitely should apply to restore, and to piggyback off of what canuck78 said you should apply for the open work permit as well. I recommend doing it on the same form as I have done, but if you still have any doubts then I would file a restoration the way that the website recommends, and then also apply for an open work permit with your PR. That will significantly affect the length of your OWP processing though, since you won't get it until your status is restored or until you get AIP
