NO SMOKING in the Workplace - Including Cannabis




Workplaces in Ontario are required to post No Smoking signs prohibiting smoking of tobacco, cannabis (including medical cannabis), and electronic cigarettes.


The Smoke-Free Ontario Act, 2017 prohibits smoking or vaping in enclosed workplaces – even when the workplace is closed.


Enclosed workplaces includes any part of a building, structure or vehicle with a roof that an employee works in or visits, even during off-hours including:

  • Office building
  • Trailer office on a construction site
  • Delivery truck
    Employers Must Post Signs
    Employers and proprietors of an enclosed workplace are required by law to post signs at each:

  • Each entrance
  • Exit
  • Washroom
    You can post a 2 signs for tobacco and e-cigarettes OR just one combined sign. Order your signs from your local public health unit or download them.
    There are other legislated posting requirements in the workplace including employment standards and health and safety. To learn more about statutory requirements for Ontario employers, please contact us at Dale & Lessmann LLP.
