The comment I'd like to add is one of the issues with legislation is that it doesn't allow for growth. As technology advances, we always have to update our legislation, rather than having legislation that permits it in some way.
If there were a way to find language for lawful access legislation that was similar to the general warrant provisions of the Criminal Code, for example, which allow a police officer, upon judicial review, to engage in a technique that would otherwise constitute an unlawful search or seizure.... It's basically something that has never been done before, but you want to try a technique, and as long as you can demonstrate your reasonableness before a reviewing justice, they can authorize the police to do that. There are a number of instances when the police have used those kinds of techniques in years gone by with general warrants.
So perhaps we could get something in lawful access legislation that would allow the police, again, to adapt their techniques as technology advances. You're asking the justice who reviews it to almost be really creative along with the police officer into applying the new techniques with respect to new technology.
