Can the expiration date on the Record of Landing (IMM1000) be extended?
The expiration date on the Record of Landing (IMM 1000) is directly related to the validity of medical results and/or passport expiration date for the person who possesses the Record of Landing. You should make every effort to appear at a Canadian Port of Entry before the expiration date of the Record of Landing. Extensions of the Record of Landing are very rare. The expiration date of the Record of Landing cannot usually be extended unless the holder undergoes another immigration medical examination.
