This is what I got from the customer service agent in chat on 05-Aug-2022.
If you are located in the United States of America and have received the passport request letter from IRCC (Immigration, Refugees and Citizenship Canada), your passport can be submitted either in person or by courier to the CVAC (Canada Visa Application Center).
Please drop off, or send to the CVAC in a single envelope, all of the following documentation:
The passport request letter you received from IRCC.
The original and valid passport.
Your contact information on a single sheet of paper, including your email, phone number and return mailing address.
Two copies of the TT services consent form, second page duly completed and hand signed, the link to download is: https://assets.ctfassets.net/xxg4p8gt3sg6/2LVFqatIwJhm9JEP5nqUYL/3c71a4a1468630ef0845c423a3cd41e2/ConsentForm_-TTS-English-IN-VAC-Final.pdf
If you purchase the two-way courier service, do not forget to attach a printed copy of the payment invoice, thrown by the system just at the moment of paying with your card.
Below charges must be paid, by card directly at the CVAC, or in the form of a Money Order or Cashier’s check, in favor of “VFS Services (USA) Inc.” Fees must be in US dollars:
