Friend had a 6 month visitor visa and was successful in obtaining an extension for total of one year stay. Friend received the email confirmation "your application to remain in Canada as a temporary resident has been approved. A secure document has been mailed to you..." The problem is the mailing address had a one digit error, the friend never received the physical documents because of the addressing error. The extension was valid to November 16, 2018 (ten days from now). The friend has since returned to their home country, before the November 16, 2018 expiry date of their visa, so is in compliance with the visa and extension. Question: How important is it to have the physical documents? They have the email confirmation. We cannot get through to a live person at the 1-888-242-2100 number to ask because of high call volumes, "call back later". Does the absence of physical documents in hand affect anything such as a future visit to Canada? I'm thinking it won't but the friend is nonetheless concerned. Should the friend retain proof, say the airline e-ticket, that they indeed left the country before the end of the validity period? Or are the physical documents only necessary if they are asked for proof of their temporary residency status while in Canada? Now that they have left, the physical documents are moot? Thanks, any help will alleviate the concern.
