Frequently Asked Questions
Can a Canadian employer still prohibit cannabis use even though it is legal under the Cannabis Act?
Yes. The Cannabis Act (SC 2018, c. 16) legalized recreational cannabis for adults but did not change an employer's duty to maintain a safe workplace under provincial OHS legislation. Employers may prohibit cannabis consumption on the worksite, during work hours, and may prohibit workers from arriving in an impaired state - regardless of when or where the cannabis was consumed. The principle is the same as alcohol: legal outside of work does not mean permitted at work.
What are the signs of cannabis impairment a supervisor should watch for in a Canadian workplace?
Observable signs include physical indicators such as red or glazed eyes, slurred or slowed speech, poor balance or coordination, and the odour of cannabis. Behavioural and cognitive signs include slower reaction times, difficulty following multi-step instructions, disorganized thinking, and heightened irritability. Performance indicators include an abnormal increase in errors, near-misses, or difficulty operating equipment at normal proficiency. Supervisors document what they observe - they are not required to determine what substance, if any, caused the impairment.
Is random drug testing legal for Canadian employers?
Generally no - Canada imposes significantly tighter restrictions on random drug testing than the United States. In Irving Pulp and Paper Ltd v. CEP Union (2013 SCC 34), the Supreme Court of Canada held that a dangerous workplace alone does not justify random testing; the employer must demonstrate that a documented, workplace-specific substance abuse problem exists. Post-incident testing and reasonable-cause testing (based on observed impairment signs) are permissible in safety-sensitive workplaces when properly documented.
If a worker tests positive for cannabis, can the employer fire them?
A positive drug test alone does not justify termination in Canada. Cannabis metabolites remain detectable in urine for 3 to 30 days after use - far longer than any impairment lasts - so a positive result proves past exposure, not current impairment. When an employer receives a positive result, human rights law requires assessing whether the worker has a substance use disorder, which is a protected disability under the Canadian Human Rights Act (R.S.C. 1985, c. H-6, Section 3.1). The employer must explore accommodation options before proceeding to discipline or dismissal.
What is an employer's duty to accommodate a worker with a substance use disorder in Canada?
Substance use disorder is a protected disability under the Canadian Human Rights Act and all provincial human rights codes, including Ontario's OHRC and Alberta's AHRC. Employers must accommodate affected workers up to the point of undue hardship - in practice this means allowing access to treatment (medical leave for detox or rehabilitation without automatic discipline), offering modified duties during recovery, and establishing structured return-to-work agreements. An employer that terminates a worker for substance use without first exploring accommodation options may face a human rights complaint in addition to OHS liability.
