Citizenship and Immigration Minister Chris Alexander defends the government’s proposed overhaul of the Citizenship Act. Bill C-24 will make the first comprehensive reforms to the Act since 1977. Measures include changing residence requirements, ensuring that applicants aged 14 to 64 meet language and knowledge requirements, and allowing the government to revoke the Canadian citizenship of dual nationals convicted of treason or terrorism or have engaged in armed conflict with Canada. Critics have raised concerns about the constitutionality of some measures, the creation of different classes of citizens and increased barriers to citizenship. (June 12, 2014) UPDATE: Bill C-24 received royal assent on June 19.
