As I understood, you are good and shouldn't matter as it is the mailing address...but explicitly mention it, so there is no ambiguity for the examining officer.
As per IRCC, If you’re outside Canada, when you arrive in Canada
"If you’re admissible and there are no problems when you arrive, the officer will:
allow you to enter Canada as a permanent resident
confirm your Canadian mailing address where we’ll mail your permanent resident card
If you change your address within 180 days of arriving in Canada, you must tell us using the web form."
If you’re already in Canada, during the interview the officer will:
"confirm your Canadian mailing address, so we can mail your permanent resident card (PR card)
If you change your address within 180 days of getting your status, you must tell us using the web form."
