To apply as an adult, you will need to include the following with your application: A. Proof of permanent residence B. A Record of Landing (IMM 1000)—a document that is sometimes folded and stapled into your passport—if you became permanent resident before June 28, 2002; or your Confirmation of Permanent Residence (IMM 5292 or 5509)—if you became a permanent resident on or after June 28, 2002 C.
