I got same ADRs too on May 27th. Updated IMM5669, paystub and/or employment letter and payment of processing/right of permanent residency fee.It is through email. One more friend who was transferred to Etobicoke got ADR.
IMM5669 form, employment letter and latest 3pcs paystubs.
I sent via e-mail as their instructions suggested but immediately received following automated reply:
“
Good day,
Thank you for contacting Immigration, Refugees and Citizenship Canada (IRCC).
Please note that a longer delay may be experienced to process your inquiry as only critical functions are being maintained at this time by IRCC offices.
If your request is urgent or if you wish to submit an update or documents, we recommend that you do so via our IRCC Web form.
“
And in this reply they recommend submitting or updating documents via web-form, so I’m kinda confused.
