So the way I did it (and I don't know if there's a better way to submit the documents) was via this link: https://secure.cic.gc.ca/enquiries-renseignements/canada-case-cas-eng.aspx?Hi ,
how did you send the webform?
I did not find any option for Non EE applied online.
And on "Type of application/enquiry " I selected the option "Replacement documents, Amendments to documents and Verification of Status documents"
