Thank you.
As I see it, the reason we have asked you to come back is that we have heard contradictory testimony on the operational nature of existing technologies and on the ability to detect drugs in the body at the time the individual is supposed to be impaired by those drugs. We're told that there are residues that make it possible to detect the presence of certain drugs in the body 12 and even 15 days after they are taken. It's obviously more difficult to establish a conclusive correlation between the time when the drugs were taken and the impairment at the time the driver is at the wheel.
I don't know whether documents were tabled yesterday, since I was in the House for Bill C-59, but I would like you to explain to us in detail both how the tests work and in what they consist. For example, as regards the drug recognition experts, I would like it to be explained to us where they will be, how they will be trained and what budgets will be available for that purpose. Let's start with a fairly accurate description of the standardized sobriety test. Your colleague gave us a little information yesterday about alcohol. Then let's continue with the 12 steps for the drug recognition experts so that it's clear. I would like that information to be submitted to committee members so that it's educationally conclusive for us when we do the clause-by-clause consideration of the bill.
