As everyone is aware Canada plans on making recreational marijuana use legal by July 2018. However as hard as I try, I cannot find any info about how this will affect current rules and regulations regarding it's use by people who hold jobs that are "safety sensitive" and are required to submit to drug testing as a condition of employment. The only articles I can find are about medicinal use at work or on the job recreational use. But what I am trying to find out, is can a worker be tested and suspended or fired for testing positive for marijuana after recreational marijuana is legalized if the worker is only using marijuana off company premises while not on company time? Can companies say you are never allowed to use marijuana (in Canada) once it becomes legal?
