Need help in booking appointment for COPR >PPR

[canadiandream2019]

Hi Folks,

I sent email for appointment booking (IRCC.PRA-RVPR.IRCC@cic.gc.ca) last week but today got email in response saying below.

• Surname and complete given name - exactly as they appear on the passport or identity document,
• Date of birth (YYYY-MM-DD),
• Country of birth,
• Client ID Number, UCI or Application Number,
• Type of application,
• Expiry date of your COPR document,
• Current address,
• Telephone number(s),
• Email address, and
• All documents submitted with your previous request.

I have provided all the information but I am confused what does the last point mean? I am inland CEC.
Do I need to provide the COPR letter in the email? or something else?

Thanks for you help in advance
