If she does come to Canada you will definitely have to inform them of the change of address. If you don’t they’ll send a PPR request as of she we’re still outside the country. (Trust me, it’s a headache to try and get in contact with them to have them send a new PPR)
Make sure you send a webform and follow up on it.
I did came to know that if the applicant (outland application) is in Canada when you receive passport submission, is to send the passports to Ottawa office with Xpresspost envelope (self addressed pre-paid), so that they can send it your mailing. Hope its as simple as it says.
