Even though cannabis is legal, there are still rules that need to be followed for your safety, and to protect you from penalties such as fines or jail time. Know the laws so you can follow them and protect yourself and others from harm.

19. The Ontario Cannabis Act 2017 prohibits anyone under the age of 19 from purchasing or possessing cannabis. It is also a criminal offence to provide cannabis to someone who is under 19.

You can purchase and possess up to 30 grams (about one ounce) of dried non-medical cannabis for personal use at one time, or share with another adult aged 19 or over.

You cannot smoke or vape cannabis or use other cannabis products (i.e. edibles), both medical or non-medical, anywhere tobacco use is prohibited, as well as some additional places:

  • Enclosed public places, enclosed workplaces and other sheltered areas with a roof and more than two walls (such as bus shelters)
  • Vehicles and boats being driven or under someone’s care or control
  • Indoor common areas in condominiums, apartment buildings and university/college residences
  • Restaurant and bar patios and public areas within nine metres of a patio
  • Publicly-owned sporting areas, spectator areas, community recreation centres and public areas within 20 metres of those grounds
  • Reserved seating areas of outdoor sports or entertainment venues
  • Schools and school grounds, and public areas within 20 metres of those grounds
  • Children’s playgrounds and public areas within 20 metres of playgrounds
  • Child care centres, and places where an early years program is provided
  • Places where home child care is provided, regardless of whether children are present
  • Nine metres from the entrance or exit of a public hospital, private hospital, psychiatric facility, long-term care home and independent health facility

In addition, municipalities in Windsor-Essex County have smoke-free by-laws which have additional prohibitions on the use of tobacco and non-tobacco products (such as cannabis) and vape products. See Smoke-Free Spaces for a description of your local smoke-free by-law.

Not at this time. It is currently illegal to produce, sell, or buy edible products or to have them in public.

Yes. Using cannabis while operating a motorized vehicle or with cannabis in your system is illegal and will be treated the same way as driving under the influence of alcohol. Police can legally request a driver to undergo testing to confirm impairment by drugs and you will be subject to serious penalties.

Young, Novice and Commercial Drivers - Drivers age 21 or under, novice drivers (drivers who have a G1, G2, M1, M2, M2-L or M2-M licence), and commercial drivers are prohibited from having any cannabis or other drugs in their system and face penalties and potential criminal charges. That means that Ontario has a zero tolerance approach to both alcohol and drugs for these drivers.

All Drivers - If police find that you have cannabis or alcohol in your system above legal limits, or that you are impaired by any substance including illegal drugs, prescription drugs or over-the-counter medications, you will face severe consequences and potential criminal charges.

Medical Cannabis Users - If a police officer is satisfied that you are legally authorized to use cannabis for medical purposes, you will not be subject to Ontario’s zero tolerance drug requirements for young, novice and commercial drivers. However, you can still face penalties and/or criminal charges if a police officer finds that your ability to drive is impaired. Even if you have been authorized to use cannabis or another drug by a health care professional, it is your responsibility to ensure you are not impaired while driving.
