As of November 9, 2021, Immigration, Refugees and Citizenship Canada (IRCC) was finalizing most applications of grants of citizenship, received between August 4 and 10, 2019, per IRCC (shown below). It may mean that the processing time could stand at about 26 months.
The lengthy processing time is a result of impacts of the ongoing COVID-19 pandemic, yet normally the timeline stays at 12 months, according to IRCC (shown below).
If you have applied for grants of Canadian citizenship, you may have to expect delays in the processing. To check the up-to-date processing time and application status, please refer to IRCC.
