Legislation History

When the time came for cannabis laws in Quebec, Canada to pass its version of marijuana legalization, the opposition Parti Quebecois wanted tighter controls and voted against the legislation.

Despite the divisions, Quebec Liberal Party Premier Phillipe Couillard’s government in June 2018 passed Bill 157  enacting the Cannabis Regulation Act, establishing the Société québécoise du cannabis (SQDC) to oversee sale and distribution, and amending highway safety standards.

Although marijuana supporters denounce some of the more restrictive measures, such as the prohibition of home growing and the few stores, all owned by the government,  where cannabis will be available initially, Quebec announced it would be ready for legalization on October 17, 2018.

Even with the constraints, Quebec was more permissive in some respects than other provinces or territories, allowing more consumption in public areas and adopting a minimum age of 18 to buy or consume marijuana. All other provinces except Alberta enacted the federal government’s  19-year-old limit.

The opposition parties had argued, among other things, for more limits on public consumption and the Coalition Avenir Quebec had lobbied for a 21-year-old age limit.

Despite a reputation as a party province, Quebecers have a more moderate streak when it comes to marijuana. Consumption in the province is in the middle of the pack among the provinces, but a CROP, Inc. poll by Radio Canada found only 46 percent of the population favored marijuana legalization, compared with 58 percent nationally.

As part of its bill legalizing recreational cannabis, the province imposed a number of highway safety amendments that include a “zero-tolerance” policy for driving with any detectable amounts of cannabis or alcohol in the body once effective equipment for detecting cannabis in saliva is available and approved. Limited exceptions may be made for cannabis medical users.

Police can immediately hold off licenses for 90 days if their evaluation shows drug and/or alcohol impairment, or if a driver refuses marijuana testing. Vehicles can be held if operators have past convictions for drugs or alcohol. Drivers can also face the charge of $1,500 to $5,000, installation of an interlock device, and other penalties, including jail time, for operating a vehicle under the influence of marijuana.

Under federal guidelines, drivers face graduated penalties depending on levels of drug and/or alcohol concentrations, as well as previous offenses.

Federally, the legal limit for THC in the bloodstream is two nanograms per milliliter. A nanogram is one-billionth of a gram. Concentrations between two (2) and five (5) nanograms result in a fine up to $1,000. Concentrations of five (5) or more nanograms will result in a $1,000 minimum fine for a first offense, imprisonment of 30 days or more for a second offense, and imprisonment of 120 days or more for a third offense. Penalties for drug-impaired driving accidents can range from 18 months to as much as life imprisonment for a fatal crash.

How to Purchase

When legalization takes effect, Cannabis Laws Quebec Canada dictate that purchasers in Quebec will only be able to purchase recreational marijuana through stores and online through the public SQDC website.

The Quebec government will have control, operate, and distribute all legal marijuana in the province. The SQDC plans to have 20 stores open by Oct. 17, 2018 with expansion to possibly 100 or more within three (3) years. The SDQC also announced that it would have an online purchasing platform up and running by the time the new laws go into effect.

According to media reports the first four store locations in Montreal will be located near the busy Berri-UQÀM, Radisson, Jean-Talon and Lionel-Groulx Métro stations.

Minors will not be allowed inside, and stores will be stand-alone, marijuana-only operations with about 150 products. Displays will not be visible to passers-by and stores must be at least 250 meters, or about 820 feet, from schools. In Montreal, the distance is 150 meters, or about 492 feet.

Purchasers are permitted to buy a maximum of 30 grams,  or 1.6 ounces of dried marijuana at one time, or equivalents in fresh cannabis and cannabis oils.

Premade edibles and extract will not be obtainable until the federal government authorizes such through legislation that they anticipate having in place on or before October 17, 2019, although purchasers can create their own edibles as they wish.

Employees will be required to pass government-sponsored marijuana training programs.

Where is it Safe to Consume?

Cannabis Laws Quebec Canada dictate that Smoking will generally be authorized in places where tobacco smoking and vaping are allowed. It will be allowed in private residences and rentals unless prohibited by lease or property agreements. Landlords will have until January 17, 2019 to put marijuana restrictions into leases.

Consuming marijuana in public is prohibited in most restaurants, bars, hospitals, schools, bus shelters, bike paths or sports facilities. Smoking is also banned on and within nine (9) meters, or 29 1/2 feet, of areas frequented by children, such as playgrounds or pools. It is worth noting that public parks that don’t serve as playgrounds will permit consumption of marijuana as they allow consumption of tobacco products.

It is illegal to consume marijuana while operating a vehicle for either drivers or passengers. The law applies regardless of whether the vehicle is in motion. In a vehicle, marijuana must be stored in a sealed container that is not accessible to the driver or passengers during transport.
