I did it!
I entered Canada at the land border without getting reported!
Couldn't have done this without the help of this great forum, especially your superb help Leon. Thank you again
. I hope my experience would benefit and give hope to other PRs who are outside Canada with an expired PR card but fear that applying for a travel document could jeopardize their permanent residence status, just like I was. Immigration really does seem to be much more lax than that at airports, however, to minimize the chance of getting reported as much as possible, I strongly advise those who'll be entering Canada at the US Canada border to present the Canadian officials with good, documented reasons as to why they couldn't meet their residency requirements (in my case I told them that I left Canada unintentionally with my parents) and/or proof that they have or will have strong ties to Canada such as family members in Canada, proof of acceptance at a university (I presented both of those as well as a copy of my invitation to attend the citizenship ceremony and I think the officer checked on his computer that my Father and Mother are actually in Canada). At first I gave the Canadian border officer my passport and confirmation of permanent residence then when he asked if I have a PR card, I presented my expired card along with the copy of my citizenship ceremony invitation. When he saw that the card was expired, he asked me how long I've been outside Canada, I told him 2 years and 9 months and went on to explain in detail (as he requested) my history since becoming a PR ( he took notes on a green piece of paper). After that he called a CBSA officer to lead me to immigration, where I essentially repeated my story but in a bit more detail (and he was a bit more skeptical than the first officer; he asked me when I finished high school and what I was doing in Egypt after finishing high school). He checked that my Father and Mother were in Canada then just told me "You're free to go". He was about to forget to stamp my passport and he forgot to give me back my confirmation of permanent residence, so I requested it (so be sure to take back all your important papers). Also, he asked me whether we mentioned in the citizenship application that I've been outside Canada at high school in Egypt, and so I reminded him that as a minor on my father's application I didn't need to stay in Canada for 1095 days to get accepted for citizenship. That's why it's important that you study the related CIC rules to know your rights as a PR and that you speak truthfully and confidently.
