Yes, revenue Canada, service Canada, and Access Nova Scotia all have the new address. Email stated QR code sent electronicly, drivers license, passport, and anything with name and current address, from a credit card bill to insurance policy, including property tax bill.

Drivers license has my old address, but info updated with Access Nova Scotia. Went to the post office today with the QR code, dl, passport, and property tax bill with my current address, as instructed for in-person verification. They scanned my dl, denied. They told me it hasn't worked for anyone.
