Canadian Tribunal Upholds Air Transat's 2018 Cannabis Ban for Flight Attendants

An 80-page Quebec employment ruling backed Air Transat’s policy barring flight attendants from using cannabis on or off duty, rejecting a union challenge after Canada legalized marijuana in 2018.
THC can remain detectable in hair for up to 90 days, and the tribunal said aviation’s safety-sensitive nature and the lack of a reliable real-time impairment test justified a zero-risk approach.
The judge also dismissed CUPE’s privacy argument, ruling passenger safety outweighs crew members’ off-duty privacy rights and calling the policy a proportionate, minimally impairing restriction.
CUPE said it is still reviewing the decision but maintains the policy is excessively intrusive and argues Air Transat should compensate members for the extreme off-duty discipline it demands.
The ruling aligns with broader aviation practice: in the U.S., federally regulated flight attendants can be fired for positive cannabis tests, and 25% of safety-sensitive workers face random drug testing in 2026.

Why are flight attendants banned from legal off-duty cannabis use while alcohol, a known impairing substance, is permitted?

Does ensuring passenger safety justify employers controlling the legal, private activities of their off-duty employees?
