First, you have to be clear about the difference between accompanying and non-accompanying. "Accompanying" means she will get PR at the same time as you (even if she does not plan to move to Canada immediately). "Non-accompanying" means you will have to sponsor her later, so it will take more time. Second - if you still choose "non-accompanying," you need to add her to your application as non-accompanying and she still needs to fill out the forms, submit police clearance(s), and complete the medical exam. This is what you MUST do to preserve the right to sponsor her later. But you do not need to pay the application fee or RPRF at this time. Unless she does not plan to move within the 3 years after you become a PR (and cannot meet the residency requirements), it is much better to include her as "accompanying."
