Cannabis edibles, extracts, and topicals are legal in Canada for those 19 and older, and will soon be available in Ontario through licensed retailers. If you are thinking about using these products, there are things you need to know to lower the risk of harm and to stay within the legal rules for possession, purchase, and use.
Yes. Police can legally request a driver to undergo a Standardized Field Sobriety Test, oral saliva test, or a blood test to confirm impairment and/or presence of drugs over the legal limit (illegal, prescription, or over-the-counter medications). If you are found impaired to drive, you will be subject to serious penalties ranging from fines and immediate license suspensions, to criminal charges and jail time.

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.
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

No. It is illegal to bring cannabis into the United States or into Canada. Taking cannabis or any product containing cannabis (medical or non-medical) across the Canadian border is illegal and can result in serious criminal penalties both at home and abroad.
If you do have cannabis or products containing cannabis with you when you enter Canada, you must declare them to the Canada Border Services Agency. If you do not declare these products, you could face an arrest and criminal charges. Learn more Travel.gc.ca/cannabis
