Drug trafficking is an offence under section 5(1) of the Controlled Drugs and Substances Act, and for Schedule I substances such as cocaine, fentanyl, heroin, and methamphetamine, it carries a maximum penalty of life imprisonment. Trafficking is defined far more broadly than most people expect: selling is trafficking, but so is giving, transporting, delivering, or even offering to do any of those things. These cases in Toronto and across Ontario are usually won or lost on the police investigation, because most trafficking files begin with a search, a surveillance operation, or an informer.

What is drug trafficking under Canadian law?

Under the Controlled Drugs and Substances Act, "traffic" means to sell, administer, give, transfer, transport, send, or deliver a controlled substance, to sell an authorization to obtain one, or to offer to do any of these things. No money needs to change hands: passing drugs to a friend can be trafficking in law. Section 5(1) prohibits trafficking itself; section 5(2) prohibits possession for the purpose of trafficking, which is how police charge a person found with a quantity of drugs, packaging, scales, cash, or messages suggesting sale rather than personal use.

To convict, the Crown must prove the substance is a controlled substance (through certificates of analysis), that the accused committed an act of trafficking or possessed the substance intending to traffic, and knowledge. Possession requires knowledge and control, and in shared cars and residences that is often the live issue.

Penalties for drug trafficking in Ontario

Penalties depend on the schedule of the substance:

Schedule I (cocaine, fentanyl, heroin, methamphetamine, and others): maximum of life imprisonment.
Cannabis outside the legal regime is prosecuted under the Cannabis Act, with its own penalty structure.

Parliament repealed the mandatory minimum sentences for these drug offences in 2022 and restored the availability of conditional sentences (house arrest) in a wider range of cases. Sentencing therefore turns on the substance, the quantity, and the offender's role and circumstances. For hard drugs, and for fentanyl above all, Ontario courts impose severe sentences, with penitentiary terms the norm for anything beyond the lowest level of street trafficking. Bail is also harder: a person charged with trafficking punishable by life imprisonment bears a reverse onus at the bail hearing, meaning the defence must show why release is justified.

Possible defences to a drug trafficking charge

Depending on the evidence, defences may include:

Charter section 8 challenges to the search: warrantless searches of vehicles and people, the sufficiency of the information used to obtain a search warrant for a residence or phone, and how the search was executed. Excluding the drugs usually ends the prosecution.
Section 9 challenges to the stop or detention that produced the evidence.
Possession issues: whether the Crown can prove knowledge and control, particularly in shared vehicles, apartments, and stash locations.
Purpose: whether the quantity and circumstances actually prove an intent to traffic rather than personal use, an issue often fought through expert evidence.
Entrapment: where police provided an opportunity to commit an offence without the required reasonable suspicion, including in phone-based, dial-a-dope investigations. A finding of entrapment results in a stay of proceedings.
Disclosure and delay: gaps in the investigative record, informer-related disclosure litigation, and unreasonable delay under section 11(b) of the Charter and the Jordan framework.

Frequently asked questions

What is the difference between trafficking and possession for the purpose of trafficking?

Trafficking is the act itself: selling, giving, transporting, or offering. Possession for the purpose is having the substance with the intent to traffic it, usually proved through quantity, packaging, cash, scales, and messages. Both are charged under section 5 of the Controlled Drugs and Substances Act and carry the same maximums.

Is sharing drugs with a friend trafficking?

It can be. The legal definition of trafficking includes giving or delivering a controlled substance, with no sale required. Whether such a case is prosecuted, and how it is sentenced, depends on the substance and circumstances.

Will I go to jail for a first trafficking offence?

For Schedule I substances in Ontario, jail is the usual outcome on conviction, and fentanyl cases attract penitentiary sentences. That said, the mandatory minimums were repealed in 2022, conditional sentences are available in some cases, and many prosecutions fail on Charter grounds before sentencing ever happens. Outcomes depend on the evidence.

Can the police search be challenged?

Often, yes. Most trafficking cases begin with a search of a person, vehicle, home, or phone, and section 8 of the Charter requires those searches to be reasonable. Where the search was unlawful, the court can exclude the drugs, which typically collapses the Crown's case.

Can I get bail on a trafficking charge?

Yes, though the starting point is harder: for trafficking punishable by life imprisonment, the accused bears the onus of justifying release. A strong, well-prepared release plan makes a substantial difference at the bail hearing.

What if the drugs were not mine?

Possession requires proof of knowledge and control beyond a reasonable doubt. In shared cars and residences, the Crown's ability to tie the drugs to one particular person is frequently the central weakness in the case.
