For applicants for permanent residence
- Immigration, Refugees and Citizenship Canada (IRCC) letter (IRCC used to be called Citizenship and Immigration Canada, or CIC). The letter must:
- be on IRCC letterhead, addressed to you as applicant
- state IRCC has confirmed you meet the eligibility requirements to apply for permanent residence in Canada and you have not yet been denied.
