The entry/exit program needs to be examined from a broader historical perspective.
It is important to remember that in the past, democratic countries did not collect information on the exits of their citizens. This was related to the freedom of movement of citizens, and the government didn't control this kind of activity.
Following the events in September 2001, several countries imposed the collection of information or gathered information for border management and national security purposes. Canada was among the last to do so.
To date, the information collected has focused on non-Canadians for border management and national security purposes. According to the Bill C-21, the gathering of information and the sharing of information will also apply to citizens.
It is important to understand that we are crossing a boundary. Historically, democratic countries did not collect this kind of information about their citizens. However, things have changed as a result of the events in September 2001, and it is now a widespread practice that also aims to ensure the integrity of social programs. We are moving in this direction.
Given the importance of combatting fraud involving these programs, and the relatively limited and non-sensitive nature of the information, this seems reasonable. However, it must be understood that this evolution in the history of democratic countries has occurred.
