Did she give biometrics in last 10 years? Is she on visitor visa? Biometrics is mandatory for PR. If she just came in as a visitor and hasn't done biometrics then she will have to leave Canada. You can't do biometrics in Canada as of now. If she has visa for US then she can go there and get it done, otherwise she will have to go back to home country.
@others: pls correct me if I am wrong
When someone I know got a request for Biometric she was in Canada too on a temporary visa but the request was from Visa Office New Delhi, She did her biometric at RCMP and upload the document on MYCIC account.
