A recent labour arbitration decision from Saskatchewan has framed what might be the boundaries around workplace consumption of medical marijuana.

In Kindersley (Town) v Canadian Union of Public Employees, Local 2740, 2018 CanLII 35597 (SK LA), an employee was dismissed for vaping medical marijuana while operating the employer’s vehicle. The employee had previously disclosed to his employer that he had had a prescription for medical marijuana and was allowed to vape marijuana in the workplace.

The employee was not allowed to operate his employer’s vehicle for approximately 30 minutes following vaporization of marijuana. He was also not permitted to operate heavy machinery for 1 hour after vaping.

The employee was later discovered to have been vaping while driving and immediately before driving. As a result, the employer summarily dismissed the employee. The employee’s union filed a grievance challenging the summarily dismissal.

The arbitration board held that, despite the lack of proof of the employee’s impairment on a balance of probabilities, the vaping of marijuana immediately prior to and while operating the vehicle entitled his employer to summarily dismiss him. The board also emphasized the fact that the employee appeared to lack respect for the limits of his employer’s medical accommodation of him, and cared little for the safety of his coworkers by vaping while other employees were in the vehicle with him.

The arbitration board found the decision to summarily dismiss was not excessive discipline. The board noted that while the employee should not be deprived of using marijuana for the medical purpose intended, ultimately “there is no reason he could not have done this more discreetly rather than in the presence of his co-workers and while driving.”

What does this case tell us?

While it is a Saskatchewan decision, the same principles apply in Ontario: having a prescription for medical marijuana is not a free licence to consume it whenever and wherever you like, particularly while working for an employer. Moreover, even if your employer has expressly accommodated you by allowing you to consume marijuana in the workplace, not
adhering to the terms of that accommodation could result in dismissal without notice.

It is also important to note this case applies to unionized employees, who have greater protections from dismissal than non-unionized employees. This suggests that, in a non-unionized workplace, the threshold for misconduct meriting dismissal based on the consumption of medical marijuana could be lower.

According to Ontario’s human rights laws, all employers must accommodate employees with a disability to the point of undue hardship. This accommodation could include allowing employees to use medical marijuana while at work. However, employees must comply with the limits of their employer’s accommodation, so as to avoid undesirable disciplinary measures.
