if you applied INLAND, did you include an Open Work Permit with your application? If so, then you would enjoy the benefit of IMPLIED status until the OWP is approved after stage 1 (currently taking 16 months). During this time, you can not leave Canada, or your implied status would expire.
If you did NOT include an open work permit with your inland application, or your applied Outland, then what you will want to do is apply to change your status to visitor on the CIC website. the cost is $100, and PR applicants are rarely denied. I would recommend requesting a 16-24 months extension to ensure you have proper status until inland approval. if you applied outland, then 12 months is probably enough time to request. It is very common for pr applicants to get approved for this much of an extension.
