Mr. Speaker, these are situations that must be assessed on a case by case basis. Sometimes it is impossible to get UN consent, because certain members have a veto on the security council.
However, on some occasions in the past, when it was necessary to protect the lives of civilians and there was no consent from the United Nations, Canada has joined peacekeeping missions, even without the explicit authorization of the United Nations, when one or two members of the security council had refused to support the initiative.
