Making changes after the application is submitted
Applicants should report any change of address or telephone number to Immigration, Refugees and Citizenship Canada (IRCC) (formerly Citizenship and Immigration Canada or CIC) right away. They can do this online or they can contact the Call Centre at 1-888-242-2100.
Applicants must also inform IRCC of any changes in family status, such as marriage, divorce, or the birth of a child. This has to be done in writing.
