Arrest without warrant is an extraordinary power. If the position of the government was so obvious, why has it taken until 2011 for this to come forward as an obvious required amendment to the Criminal Code, or to the powers of arrest of a peace officer?
The concern here is that there could be conditions of parole that could be relatively minor. In some cases it could be as minor as a person who should refrain from alcohol use. For example, if somebody was seen sitting in a club with a beer bottle in front of them and a police officer decides he wants to arrest the person, he can go ahead and do so without a warrant because he may be somehow aware of the conditions of parole.
If someone is misbehaving on parole, the person who is responsible for that is the parole officer. Arresting someone without a warrant, you know, is a pretty.... There are not a lot of offences in which you can do that. There are many offences where you can't arrest someone; you can only issue an appearance notice, or you can issue a summons to appear.
If this were such a necessary power, it would already be there. We haven't seen examples as to why this power is actually necessary.
