The offence of sale of cannabis to an adultcannabis sale legal limits are strict: only federally or provincially authorized sellers may sell cannabis, and only in specific ways. Under Section 10 of the Cannabis Act, selling cannabis to anyone – including an adult aged 18 or over – without proper authorization is a criminal offence. This is a hybrid offence, meaning the Crown can choose to proceed either by summary conviction for less serious cases, or by indictment for more serious illegal sales.
The Legal Definition
Cannabis Act, s. 10(1)(a): “Unless authorized under this Act, it is prohibited to sell cannabis, or any substance represented or held out to be cannabis, to (a) an individual who is 18 years of age or older.”
In plain English, this means that no one is allowed to sell cannabis to an adult unless they are properly licensed or otherwise authorized under the Cannabis Act. It does not matter that the buyer is over 18, that cannabis is legal in Canada, or that the quantity is small. If the seller is not an authorized retailer, distributor, or producer under federal or provincial rules, the sale is illegal.
The Act also defines “sell” very broadly. It includes not only a completed sale, but also offering cannabis for sale, displaying it for sale, or possessing it for the purpose of sale. It also covers cases where the substance is not actually cannabis, but is represented or held out to be cannabis. So, advertising cannabis for sale on social media, holding large amounts clearly packaged for resale, or handing over a bag of “cannabis” for money (even if it later turns out to be something else) can all fall within this offence if done without authorization.
Penalties & Sentencing Framework
- Mandatory minimum penalty: None.
- Maximum penalty (indictable): Up to 14 years imprisonment (Cannabis Act, s. 10(5)(a)).
- Maximum penalty (summary conviction, individual): Up to 6 months imprisonment and/or a fine of up to $5,000 (s. 10(5)(b)(i)).
- Maximum penalty (summary conviction, organization): Fine of up to $100,000 (s. 10(5)(b)(iii)).
- Offence classification: Hybrid – Crown may proceed by indictment or summary conviction.
Because this is a hybrid offence, the Crown prosecutor decides whether to proceed summarily or by indictment. That choice dramatically affects the potential sentence. On indictment, the court can impose up to 14 years in prison, placing this conduct in the same range as serious drug trafficking offences. On summary conviction, the exposure is capped at six months in jail and/or a $5,000 fine for an individual. There is no mandatory minimum, so in appropriate cases sentences can be significantly lower than these maximums.
In practice, the Crown’s election will turn on factors such as the quantity of cannabis involved, whether the accused was running an ongoing or commercial operation, prior criminal record, evidence of links to organized crime, and whether the conduct undermined the regulated market in a serious way. Small, one-off sales by a first-time offender are more likely to be prosecuted summarily. Larger scale, repeated or organized sales, particularly where cannabis is sourced from illicit producers, are more likely to draw indictable charges and real jail time.
Because there is no mandatory minimum, sentencing judges retain full discretion (within the statutory maximums) to tailor the penalty. Guided by the general sentencing principles in the Criminal Code (notably s. 718 and following), a court must impose a sentence proportionate to the gravity of the offence and the offender’s responsibility. That can range from discharges or fines at the low end, through community-based sentences (like probation or conditional sentences where available), up to lengthy penitentiary terms in serious, repeat or organized cases.
Common Defenses
-
Mistake of fact about the nature of the substance sold
A key element of the offence is that the accused sold cannabis, or something they represented or held out as cannabis. A genuine, honest mistake of fact about what the substance was can, in limited circumstances, be a defence. For example, if an accused reasonably believed they were selling a legal, non-cannabis herbal product and had no intention to sell cannabis at all, they may argue that they lacked the necessary knowledge (mens rea) that the substance was cannabis. However, the bar is high: the Crown can rely on expert analysis, smell, appearance, packaging, communications, and surrounding circumstances to prove the substance was cannabis, and that the accused knew (or was wilfully blind to) that fact. The defence will fail if the accused simply chose not to inquire, ignored obvious signs, or continued selling despite indications the substance was cannabis.
-
Having legal authorization to sell cannabis
The opening words of s. 10(1) – “Unless authorized under this Act” – make authorization an essential part of the definition. If the accused in fact held a valid federal or provincial licence or authorization permitting the specific kind of cannabis sale in question, then the offence is not made out. Practically, this defence arises when there is confusion about the scope of a licence (for example, a federally licensed medical seller alleging that a sale fell within the medical regime, or a provincially licensed retailer disputing whether a sale was within their authorized location or product line). The Crown must prove beyond a reasonable doubt that the accused was not authorized, but in reality the accused is expected to produce proof of any licence they claim to have. Importantly, personal authorizations (such as to possess or grow for medical purposes) do not permit commercial sales. “Grey-market” dispensaries or individuals selling from home grow operations are almost never “authorized” within the meaning of the Act.
-
General Charter and procedural defenses
Although not specific to s. 10, accused persons often raise Charter-based and procedural arguments. If police obtained evidence (such as cannabis, phones, or business records) through an unreasonable search or seizure contrary to s. 8 of the Canadian Charter of Rights and Freedoms, or questioned the accused without respecting their right to counsel under s. 10(b), a court may exclude that evidence. If exclusion leaves the Crown unable to prove one or more essential elements (for example, the identity of the substance as cannabis, or proof that a sale occurred), the charge may be dismissed. These defences are highly fact-specific and turn on the particulars of the investigation and arrest.
Real-World Example
Imagine someone growing a few cannabis plants at home for personal use (within the legal home-grow limits of the province) and then deciding to sell some of that cannabis to a co-worker at an office party. The co-worker is 30 years old and willingly pays $40 for a few grams. The seller is not licensed by any provincial cannabis retail regulator, nor are they a federally licensed producer or medical seller.
From the seller’s perspective, this might seem harmless: both parties are adults, cannabis is legal, and the quantity is small. But under Section 10 of the Cannabis Act, this is clearly an unauthorized sale of cannabis to an adult. The home-grow authorization (where permitted) allows personal possession and use, not resale. Police could treat this as an illegal “cannabis sale” offense: they might seize the cannabis, interview witnesses, and review any text messages arranging the transaction. If charged, the Crown would need to prove that a sale occurred (money for cannabis), that the substance was cannabis, that the buyer was 18+, and that the seller had no authorization. Assuming this was a one-time, small-quantity sale and the seller had no record, the Crown might proceed summarily. A court could still impose a conviction, a fine, probation conditions, or even a short custodial sentence, and the offender would acquire a criminal record for breaching the cannabis sale legal limits.
Record Suspensions (Pardons)
Because sale of cannabis to an adult under s. 10(1)(a) is a hybrid offence, record suspension (pardon) eligibility depends on how the Crown proceeded and how the court sentenced the offender. Under the federal Criminal Records Act, hybrid offences are treated as indictable for pardon purposes unless prosecuted summarily. As a practical rule of thumb:
If the offence is dealt with by summary conviction, an individual typically becomes eligible to apply for a record suspension after about 3 years have passed since completion of all parts of the sentence (including any jail term, probation, and payment of fines or surcharges). If the Crown proceeds by indictment, the waiting period is usually longer, in the range of 5 years after the sentence is fully completed. These waiting periods are general; applicants must also meet other criteria, including demonstrating good conduct and having no outstanding charges.
It is important to distinguish this offence from simple cannabis possession offences, some of which have benefited from special record-suspension measures. Section 10 sale offences have not received the same automatic or streamlined relief. Anyone convicted of unauthorized cannabis sales who hopes to travel, work in sensitive sectors, or immigrate may wish to seek legal advice about record suspensions once the applicable waiting period has fully expired.
