Cannabis Legalization and Driving

The Traffic Lawyers Logo

It is expected that July 2018 will be the official legalization date of marijuana legalization. With the new legalization, it has drivers concerned about the Ontario roadways. What laws will be implemented to ensure the safety of the roads? 

In a recent September Global News article, a survey was conducted amongst Cannabis users and the following results were found:

  • 8% of cannabis user say they drive better after using.
  • 29% of cannabis users say that they drive the same when sober.
  • 52% say that they drive worse when using cannabis. 

That is a pretty high percentage of users who feel they are okay to drive while under the influence of cannabis. In a report by Statistics Canada, in 2015 there was close to 3,000 reported drug-impaired driving. There are also reports stating that the highest age group for impaired driving is 20-24, in a report released by Statistics Canada in 2015.

In an effort for the government to target young drivers, stronger penalties have been suggested for drug-impaired driving. For more on this survey, visit

With legalization approaching the government has looked towards ways to create a safer roads. As of now there will be zero tolerance for drivers aged 21 and under, or novice drivers to have a detectable presence of any substance in their system.

“The government said the other two proposed offences would be similar to the offences for drunk driving. Drivers with more than five nanograms of THC in their blood would be punished with a mandatory fine of $1,000 for a first offence, 30 days imprisonment for a second offence and 120 days for a third offence”-CBC News

All drivers have to stay under the limit which is still to be determined. There have been issues deciding how to determine what the exact legal limit for THC in the driver’s system should be. A saliva drug screening device will test the driver’s degree of intoxication. The device should be approved in the near future.

In the article by The Star released in September 2017 by Robert Benzie, “those convicted of the offence (Cannabis impaired driving), can have their license suspended for 30 days and fines up to $450. That’s a huge difference to the current penalties of a 24-hour suspension and no fine.”

The Global News Article by Shawn Jeffords stats that “any driver who fails an on roadside screening device would be fined up to $450. If the driver refuses to do the roadside test they face a fine of $550.”

Drivers who have a blood drug concentration of more than two nanograms of THC (per milliliter of blood), but less than five nanograms, could be found guilty of drugged driving under the proposed summary offence which has a maximum fine of $1,000.

With the repercussions of this offence are still undetermined for certain CBC News has released an article more recently in October, which goes more in depth of the expected limits for driving. “Drivers caught with more than five nanograms of THC in their blood would be guilty of impaired driving, while drivers with both alcohol and THC in their system would be considered impaired if they have more than 50 milligrams of alcohol (per 100 milliliters of blood) and greater than 2.5 nanograms of THC in their blood.”
