Yes. I could confirm the exact figure, but it's about one third. So detention periods are very short in many cases.
Most people being detained are waiting to be removed. On any given day, about 500 people are being detained in the three detention centres mentioned earlier, in Laval, Toronto and Vancouver. We also have about 200 spaces in provincial prisons because those individuals must be incarcerated, since they endanger the safety of Canadians, other detainees or our officers.
For instance, if someone must be removed from the country, the legislation stipulates that the removal should be done as quickly as possible. However, there may be many obstacles to the removal. For example, we may have difficulty obtaining documents from someone. The country to which the person is being removed also may not cooperate.
Forty-eight hours after someone is detained, the Immigration and Refugee Board of Canada decides whether that person should remain in detention or not. So there is a quasi-judicial process, if I may call it that, whereby the Immigration and Refugee Board of Canada determines whether detention should continue. If so, it is extended by 7 days, and then by 30 days at a time.
Therefore, all the cases you mention in which people were detained for longer periods involved a process where the board decided they should be kept in detention.
