It was reported the other day that of the approximately 44,000 who have been given a deportation order, some may have already left Canada. The problem is that we do not have exit controls in place to confirm if they did leave. We need exit controls to better monitor the number of days permanent residents spend in Canada, track visa holders (i.e., if we know they haven't left Canada, then they have overstayed their welcome), prevent parents from removing their children from the country illegally, catch anyone with a warrant for arrest before they leave Canada, etc..
