Again, this is a great panel. I wish I had more time with you.
I'd like to start off with Mr. Keith.
I'm from Oshawa, and we have a lot of unions, a lot of labour. I was happy that you brought these things forward because it parrots what I'm hearing from labour interests as well.
There are a few other things that they've brought up with me that you haven't included. These are things along the lines of blood testing, DNA collection, who would own that management cost, who pays for compliance.
There are new technologies. I guess there are other technologies for alcohol, where you can actually put it on heavy equipment. A person has to blow into it and then it will operate. If these new technologies come out, again, who pays for that? With regard to the data collected, who owns that? There are a lot of questions with this piece of legislation. You pointed out just a few of the inadequacies.
You quite rightly say that it's a complex social experiment, but it's also a poorly thought out implementation of public policy. I think by having witnesses here today, it's important that we can look at it and say that the responsibility of government is the health and safety of Canadians. This panel is I think the only one we have on looking specifically at workers.
I will ask you a few things here. We know that with smoking cannabis over the weekend, it can be in your system for days. We've heard that it can be a cumulative effect, even weeks later. Will this be problematic if mandatory testing becomes a standard in the workplace? Again, who is going to define impairment? You mentioned the blood levels. There are a lot of inconsistencies there.
Will it not be hard to punish or reprimand employees for having cannabis in their system for something they were doing legally over the weekend or in the evening in the privacy of their own home? Can you give us some advice on how that should be managed?
