To be eligible for Canadian citizenship, applicants need to be permanent residents, have resided in Canada for a minimum of three years out of the past five, show competence in either English or French, and have filed taxes if necessary. If these standards are met, a person can apply through Immigration, Refugees, and Citizenship Canada (IRCC). After sending in the application, those aged 18-54 might need to pass a citizenship test and, if approved, attend a citizenship ceremony.
