Legalizing Marijuana and Occupational Health and Safety

Marijuana Legalization

 

July 23, 2018

By David S. Reiter and Lorenzo Lisi

Last month the Senate passed Bill C-45, making the use of recreational marijuana a reality as of October 17, 2018. 

Employers, especially those engaging in operations with health and safety concerns, are legitimately concerned. Is an overhaul of their practices and policies required given the legalization of marijuana? In a word… No.

Workers do not have the right to be impaired at work. And workers do not have an absolute right to consume marijuana at work. This has already been decided and was again addressed this year by the Ontario Human Rights Tribunal in Aitchison v. L&L Painting and Decorating Ltd., 2018 HRTO 238.*

In that case, Aitchison suffered from chronic back pain and he self-medicated with marijuana. However, his employer had a zero tolerance policy in place, which required intoxicated workers to be removed from the workplace. In Aitchison’s case, his workplace was a swing stage on the outside of a building 37 floors above the ground. When he was found on the swing stage without a hard hat and untethered, while smoking marijuana, his employer sent him home. Aitchison said that it was his right to consume marijuana at work. His employer disagreed… and terminated him.

Aitchison complained to the tribunal, arguing that his employer’s zero tolerance policy was discriminatory. The tribunal disagreed. It found that

  • the policy against intoxication was rationally connected to a legitimate health and safety concern at the worksite
  • it had been adopted with an honest good faith belief that it was necessary to achieve health and safety
  • it was reasonably necessary to accomplish that purpose

This is not discriminatory. It lines up with the law that has been in place in Canada for the past 19 years, and it just makes sense.

What does this mean for employers? It means that policies concerning impairment at work are the means by which you address recreational use of marijuana. If your worksite is safety sensitive and intoxication poses a real and pressing concern to worker safetynot only can you implement a policy to prohibit marijuana consumption (or consumption of any substance which causes impairment) on the job, but you should already have one in place in light of your obligation to take all reasonable precautions to protect the health and safety of your workers under the Occupational Health and Safety Act

Employers have been addressing impairment at work for years. The advent of recreational marijuana means only that the policy can no longer treat marijuana as an “illegal substance.” It does not mean that employees are permitted to use it at work or that they can show up to work impaired.

In other words, while things may change, in many ways they will stay the same.
