Canada's Workplace Impairment and Drug Testing Forum

Drug and alcohol testing is one of the most legally fraught, most misunderstood policies in the Canadian workplace. Most employers only start asking questions after something's already gone wrong.

Under the Influence: Canada's Workplace Impairment and Drug Testing Forum

is presented by Canada's workplace media brands

HR News Canada HR Law Canada Safety News Canada

One afternoon. Every angle.

Under the Influence brings HR, legal and safety experts together for one focused virtual event. No travel, no full day away from your desk: just the questions employers are actually asking, answered by the people who deal with them for a living.

From when you can test (and when you can't), to recognizing impairment on the job, to the hardest call of all, accommodate or discipline, this is a practical playbook, not another legal seminar.

Can't attend every session live? That's OK. Your registration includes unlimited on-demand viewing of the recordings.

You'll leave knowing

  • When you can test, and when you can't
  • What a defensible pre-employment screening program looks like
  • How to recognize and document suspected impairment
  • When a positive test triggers the duty to accommodate
  • How to defend your decision if it's challenged

One event. Built for three different jobs.

Lawyers need the case law

Employment and labour lawyers advising on testing policies, human rights exposure and privacy risk.

HR needs the process

HR professionals and employers building, or defending, a workplace testing program and navigating the line between accommodation and discipline.

Safety needs the protocol

Safety managers responsible for fitness for duty and responding to impairment on the job.

The proposed program

We're working on finalizing the agenda. Stay tuned!

From suspicion to return to work: The law of workplace drug and alcohol testing

He'll cover where OHS, human rights, privacy and employment law meet, what makes a position safety-sensitive, when each type of testing holds up, and how to tell culpable misconduct from addiction when the duty to accommodate applies.
