Your wife can try to apply for a TRV (tourist visa) to come to Canada. It's often difficult to get TRV approved if your spouse has PR or citizenship. If she is approved, she can come to Canada and you can sponsor her from within Canada. If the TRV is not approved, then she will have to remain in her home country while you travel to Canada. Once you are in Canada, you will then file an outland application to sponsor her. You will need to remain in Canada while the application is being process (short 2-3 week trips outside of Canada are OK).
