I will be arriving back into Canada, one month before my PR card expires, and i have now realised that i will have an unavoidable shortfall of 20 days toward my residency obligation for renewing PR Card. Should i expect to be rejected at the airport? When using my PR Card, do i get screened by an officer or just scan my card and walk through? I am hoping to scan through, and then be physically present in Canada for 730 days, so that i meet my residency obligation before renewing PR?
