Citizenship is generally available to permanent residents who have lived in Canada for the required number of years, filed taxes as needed, and demonstrated good character. Eligible applicants must show language ability in either English or French and pass a citizenship knowledge test (if applicable). They must not be under a removal order, have any unresolved criminal issues, or owe immigration-related debts. Applicants also need to provide valid documents such as a PR card, travel history, and identification. Eligibility is determined by meeting residency, language, and legal requirements, along with a genuine commitment to becoming a Canadian citizen.
