The obligation is still going to be the overriding obligation of the employer to have a safe workplace. If an employer thinks somebody is impaired, are they going to call the police to their workplace to do their job for them? The labour regulator, federal or provincial, will intervene. There will be a union grievance. The matter will be before the courts for years.
If there's not a legislative framework that, from a common-sense perspective, says we want workers to be safe and sober, and we need some tools to do it, that's really all the suggestion is.
I don't think the goal that you're suggesting is any different from mine, but I don't think the companion legislation, Bill C-46, addresses these suggestions that we've made about the Canada Labour Code amendments.
