What would it mean? We're unanimous in wishing to do everything possible to prevent future acts of terrorism. If you have even a remote suspicion that a Canadian citizen, and in this case a non-Canadian, is attempting to murder fellow Canadians, then it becomes common sense. You want to do everything possible, given the extraordinary circumstances, to prevent a heinous crime from being committed by terrorists. If you can allow time—and there are checks and balances here for the time—to prevent a crime from happening, then the job has been done.
