Some people have experienced the impact of former section 8 of the Citizenship Act, which automatically caused them to lose their Canadian citizenship. They were actually living in Canada and did not know that this provision applied to them. They may have found out when they renewed a passport or something like that. As I mentioned, there is a discretionary grant of citizenship under subsection 5(4) of the Citizenship Act. Under that subsection, and in those circumstances, people can apply to regain their citizenship. Since 2014, I think, almost 130 people have regained their Canadian citizenship after automatically losing it.
