Hi Valp
As i know the majority of pr card will mailed directly to applicant ,however, in some cases, they ask you to pick up your card at a local office. If so, bring her passport and the original documents she sent when she applied. If she dosn't pick up her card within 180 days, the card will be destroyed and she will has to re-apply.
If she cannot come on the day of her pre-set appointment, she can pick-up her card after that date. She might however, encounter a longer wait. contact immigratin call center to make sure again.
If she is outside canada and her pr card has expired , she need to apply for travel document from a Canadian visa office abroad ! (Requirement meet residency obligation 730 days in last 5 years)
So, what date of june did they receive her application for renewal?
