Thanks to all the witnesses. It's been an informative meeting. I appreciate all the work done by each of your groups.
A couple of you mentioned the bill that we've already introduced on impaired driving, which deals with driving while impaired with drugs as well as alcohol limits and some of the defences. We know that the impaired driving sections in the Criminal Code are taking up an ever-growing and disproportionate volume. We've heard your calls for us to address some of the defences, such as the two-beer defence and the last-drink defence. You also mentioned the need for drug recognizance experts to deal with the problem of drug-impaired driving.
We know it is not yet law--it's still in the Senate--but we're hopeful that, shortly, Canadians will be served by the protection of that bill when it becomes law.
I want to talk a bit about something raised by each one of your groups. Unanimously you raised the issue of ignition interlock devices. There haven't been many questions about that. From the evidence you gave, we know the participation rate is low, yet most of you testified that these are effective where they are used.
What are some of the things we can do on the issue of the participation rate? What are the benefits of the device? And, if you will, what are some of the limitations with the ignition interlock device such that we'd have to come up with other mechanisms for instances where they fall short? Can each of you comment on that?
