She can apply for a TRV to come to Canada as a visitor. If it's approved, then she can come to Canada and submit an INLAND PR app including an Open Work Permit, and stay in Canada with you during the process.
If TRV is denied, then you will need to go back to Canada on your own and sponsor her using OUTLAND method. There is no Open Work Permit with this process. She would need to wait in home country, until PR app is entirely approved. During processing you must live in Canada, but can leave for short/temporary vacations.
