Drug Possession Lawyers Toronto

Drug possession is knowingly having a controlled substance — such as cocaine, fentanyl, MDMA or magic mushrooms — in your control without legal authority, contrary to section 4 of the Controlled Drugs and Substances Act. Possession of a Schedule I drug carries up to seven years in prison on indictment; on summary conviction a first offence carries up to six months and a $1,000 fine. Police and prosecutors must now consider a warning, a referral or diversion before prosecuting simple possession, and many charges end without a conviction. Our drug lawyers defend possession, trafficking and importing charges in Toronto and across the GTA.
If you have been charged with drug possession, trafficking, production, or importing under the Controlled Drugs and Substances Act, the stakes are high. A conviction can mean jail time, a permanent criminal record, and consequences that follow you for years. Daniel Brown Law fights these charges across Ontario — challenging search warrants, police procedures, and wiretap evidence to get results.
We regularly defend clients charged with possession of cannabis (marijuana and hashish), cocaine, heroin, fentanyl, GHB, ecstasy (MDMA), magic mushrooms, ketamine and other controlled substances. Our drug lawyers appear in courtrooms across the GTA and beyond, including Toronto, Newmarket, Oshawa, Brampton, Milton, Hamilton, and Barrie.

What does the Crown have to prove in a drug possession case?
A possession charge is not proved just because drugs were found. The Crown must prove each of these beyond a reasonable doubt.
Section 4 of the Controlled Drugs and Substances Act and section 4(3) of the Criminal Code. Cannabis is no longer a controlled substance under the Act: since October 2018 it has been governed by the Cannabis Act, which has its own possession limits.
Key considerations

The schedule sets the maximum
Cocaine, heroin, fentanyl, methamphetamine, MDMA, ketamine, GHB and oxycodone are Schedule I drugs: up to seven years on indictment. Synthetic cannabinoids (Schedule II) carry up to five years less a day, and magic mushrooms, LSD and mescaline (Schedule III) up to three years.
Diversion comes before prosecution
Since Bill C-5 in 2022, a police officer must consider taking no further action, giving a warning, or referring you to a program or community service instead of charging you with simple possession. A prosecutor may continue a possession case only if a warning, referral or alternative measures would not be appropriate.
Cannabis is treated differently
Adults may carry up to 30 grams of dried legal cannabis in public. Carrying more, or having cannabis you know is illicit, is an offence under the Cannabis Act — up to five years less a day on indictment — but amounts of 50 grams or less can be dealt with by a $200 ticket.
Possession or possession for the purpose of trafficking
Where the amount, the packaging or other evidence suggests the drugs were for sale, police may lay a charge of possession for the purpose of trafficking instead. For Schedule I drugs that charge carries up to life imprisonment. See our drug trafficking lawyers.
Calling for help in an overdose
No one who calls 911 because they or someone else is having an overdose or other drug-related medical emergency can be charged with or convicted of simple possession on evidence found because they called or stayed. The protection extends to everyone still at the scene when help arrives.
Can a drug possession charge be withdrawn or diverted?
Often, yes. The law now treats simple possession primarily as a health and social issue.

First-time offenders caught with small amounts of drugs often have options. A resolution may be available that avoids a criminal conviction entirely, or the charges may be withdrawn. Diversion programs and drug treatment courts are also alternatives in appropriate cases.
Parliament has declared that criminal sanctions for possessing drugs for personal use can increase stigma and are not consistent with public health evidence. Before charging, police must consider no further action, a warning or, with your consent, a referral to a program or service. After a charge, the Crown may carry on only if it decides a warning, a referral or an alternative measures program is not appropriate. A warning or referral cannot later be used in court as proof of past offending.
Where a case does go ahead, a judge can grant an absolute or conditional discharge, so a guilty finding need not become a conviction. And a conviction for simple possession is now kept separate from other criminal records two years after the conviction or the end of the sentence, whichever is later, and the person is deemed never to have been convicted of it. Whether diversion is realistic depends on the facts, your record and how the case is presented to the Crown — which is where early advice matters.
How do you beat a drug possession charge?
There are many ways to fight a drug charge. The right defence depends on the facts, but here are some of the most effective approaches:
Illegal search
Attacks: the evidence itself
The Charter of Rights and Freedoms protects everyone from unreasonable search and seizure. If police searched you, your car, or your home without legal authority, the drugs may be excluded from evidence. Without that evidence, charges are often withdrawn.
Flawed warrants and wiretaps
Attacks: the authority to search
Police often rely on search warrants to enter homes and vehicles. If the information used to get the warrant was misleading or insufficient, the warrant can be struck down and the evidence excluded.
Large trafficking and conspiracy cases often rely on wiretap evidence. Wiretaps must comply with strict legal requirements. If they don't, the evidence can be thrown out.
Right to counsel denied
Attacks: evidence gathered after arrest
If police arrested you and did not let you speak with a lawyer, or kept questioning you after you asked for one, any evidence they obtained may be excluded. Learn more about your right to a lawyer after arrest.
No knowledge or control
Attacks: knowledge and control
Being near drugs does not mean you possessed them. The Crown must prove you knew the drugs were there and had control over them. Drugs found in a shared car, a shared home or someone else’s bag are a common example.
The substance is not proven
Attacks: the controlled substance
The Crown must prove what the substance actually is, usually with a Health Canada analyst’s certificate. Gaps in how the exhibit was seized, stored and sent for testing can be challenged, and the defence can ask the court to require the analyst to attend for cross-examination.
Entrapment
Attacks: the prosecution itself
If police or their agents lured you into committing a drug offence you would not have otherwise committed, the charges may be stayed. Learn more about the defence of entrapment.
Do not explain yourself to the police before you get legal advice. You are not required to give a statement, and what you say about where the drugs came from or who they belonged to can be used against you.
What is the sentence for drug possession in Canada?
The penalties for drug possession in Canada depend on the type and amount of drug, the person's criminal record, and their personal circumstances. Larger quantities can attract longer sentences.
| Charge | Maximum on indictment | On summary conviction |
|---|---|---|
| Possession of a Schedule I drug (cocaine, heroin, fentanyl, methamphetamine, MDMA)CDSA s. 4(3) | 7 years | 6 months and $1,000; 1 year and $2,000 for a repeat offence |
| Possession of a Schedule II drug (synthetic cannabinoids)CDSA s. 4(4) | 5 years less a day | 6 months and $1,000; 1 year and $2,000 for a repeat offence |
| Possession of a Schedule III drug (magic mushrooms, LSD, mescaline)CDSA s. 4(6) | 3 years | 6 months and $1,000; 1 year and $2,000 for a repeat offence |
| Cannabis over the public limit, or illicit cannabisCannabis Act s. 8 — a $200 ticket for 50 g or less | 5 years less a day | 6 months and $5,000 |
| Trafficking, or possession for the purpose of trafficking, Schedule I or IICDSA s. 5(3) | Life | Indictment only |
| Importing or exporting, Schedule I or IICDSA s. 6(3) | Life | Indictment only |
| Production, Schedule I or IICDSA s. 7(2) | Life | Indictment only |
| Illegal cannabis distribution, selling or productionCannabis Act ss. 9, 10 and 12 | 14 years | Available; the maximum depends on the offence |
The fines and jail terms on summary conviction may be imposed together. No mandatory minimum sentence applies to any of these offences: Bill C-5 repealed the drug minimums in November 2022, and the 2026 changes to the Criminal Code did not restore them. A discharge is available for simple possession, and conditional sentences served in the community are available for many drug offences. Weapons, violence, dealing near a school or to a young person, and a prior drug conviction are aggravating factors at sentencing. Learn more about mandatory minimum sentences for drug offences.
Why choose Daniel Brown Law to defend a drug charge?

What happens after a drug possession charge?
If you are facing drug charges, the decisions you make early on matter.

-
Arrest, release and the diversion decision
Many people charged with simple possession are released with a court date. Police must first consider a warning or referral instead of a charge.
-
First appearance and disclosure
Your first court date begins disclosure: the search warrant and the information used to get it, police notes, video and the analyst’s certificate.
-
Crown review and diversion
We press the Crown to consider a warning, a referral or an alternative measures program, which can end the case without a conviction.
-
Charter applications
If the search, the warrant or your right to counsel was breached, we apply to exclude the evidence. These applications are argued before or at trial.
-
Resolution, trial or appeal
Cases can end in a withdrawal, a discharge, a drug treatment court program, or a trial where the Crown must prove every element. A conviction or sentence can be appealed.
Frequently asked questions about drug charges in Toronto
Answers to the questions we are asked most about drug possession and other drug charges.
Drug possession
What is drug possession?
Drug possession is a criminal offence in Canada that refers to being in control of or having custody of a controlled substance. Drug possession can be personal or constructive. Personal possession means having the substance on you, knowing what it is. Constructive possession refers to having control of a substance that is not on your person but is contained in another place — for example, drugs in the trunk of your car or hidden in your home.
Any substance listed on the schedules of the Controlled Drugs and Substances Act is considered a "controlled substance" and any person who has custody, control, or possession of these substances could face criminal charges. These substances include cocaine, ecstasy, heroin, fentanyl, GHB, magic mushrooms and methamphetamine. Marijuana was removed from the Act in 2018 and is now regulated under the Cannabis Act.
Two or more people can be in possession of the same drugs at the same time. This is called joint possession — it applies when people knowingly share control over a controlled substance, even if only one of them physically has it.
What are the penalties for drug possession?
The penalties for drug possession in Canada depend on the type and amount of drug, the person's criminal record, and their personal circumstances. Possession of a Schedule I drug such as cocaine, heroin or fentanyl is punishable by up to 7 years in prison if the Crown proceeds by indictment. On summary conviction, a first offence carries up to 6 months and/or a $1,000 fine, and a repeat offence up to a year and/or $2,000. Possessing cannabis over the legal limit is a separate offence under the Cannabis Act. Larger quantities can attract longer sentences.
That said, first-time offenders caught with small amounts of drugs often have options. A resolution may be available that avoids a criminal conviction entirely, or the charges may be withdrawn. Diversion programs and drug treatment courts are also alternatives in appropriate cases.
Police and prosecutors must now consider warnings and referrals before prosecuting simple possession, and a simple possession conviction is kept separate from other records after two years.
Will I have a criminal record for drug possession?
Not necessarily. A charge can be withdrawn or diverted, and if the case goes to sentencing a judge can grant an absolute or conditional discharge: you are found guilty but deemed not to have been convicted. Even a conviction for simple possession is now kept separate and apart from other criminal records two years after the conviction or the end of the sentence, whichever is later, and you are deemed never to have been convicted of it.
Can I be charged if I call 911 for an overdose?
No, for simple possession. If you call 911 because you or someone else is having a drug-related medical emergency, you cannot be charged with or convicted of possession under section 4(1) based on evidence found because you called or stayed, and the same protection applies to everyone at the scene when help arrives. It does not cover trafficking or other more serious charges.
Other drug charges
What is drug trafficking?
Drug trafficking means selling, giving, administering, transporting, sending or delivering a controlled substance. Even offering to do any of those things is a criminal offence. The amount does not matter — the Crown can pursue trafficking charges over a very small quantity of drugs. No drugs need to actually change hands; an offer to sell is enough for a conviction.
Trafficking prosecutions are often complex, involving months of surveillance, wiretap evidence, and confidential informant testimony. Our lawyers have significant experience challenging each of these types of evidence at trial. Read more about defending drug trafficking charges.
What are the penalties for drug trafficking?
Penalties depend on the type and quantity of drug, the offender's record, and whether aggravating circumstances exist. Trafficking most drugs carries a maximum sentence of life imprisonment. For Schedule I substances like cocaine, heroin, and fentanyl, the mandatory minimum sentences of one and two years that once applied were repealed by Bill C-5 in 2022, so the sentence is left to the judge. Trafficking a Schedule III drug such as magic mushrooms carries up to 10 years. Illegally distributing or selling cannabis carries up to 14 years under the Cannabis Act.
Offenders eligible for a drug treatment court program may receive more lenient sentences. Learn more about mandatory minimum sentences for drug offences.
What is production of a controlled substance?
Production means growing, manufacturing, or otherwise creating drugs. For cannabis, that includes growing the plants, harvesting, and processing. For harder drugs like cocaine or heroin, it means refining the raw substance into its final form.
Production charges typically follow police execution of search warrants on residential properties or commercial grow operations. Read more about marijuana production and cultivation charges.
What are the penalties for production?
Production is treated very seriously. The maximum punishment for producing Schedule I drugs like cocaine and heroin is life imprisonment. For marijuana, the mandatory minimums of 6 months to 3 years that once applied depending on the scale of the operation no longer exist: illegal cannabis production is now an offence under the Cannabis Act, with a maximum of 14 years.
What is drug importing?
Drug importing means bringing a controlled substance into Canada from another country. Under section 6 of the Controlled Drugs and Substances Act, it is also a criminal offence to export drugs or to possess drugs for the purpose of exporting them.
These charges commonly arise from seizures at airports, border crossings, and international mail facilities. The Canada Border Services Agency (CBSA) and the RCMP work together to intercept drugs entering Canada. Even a small quantity discovered at a border crossing can result in importing charges. Read more about drug importing charges in Canada.
What are the penalties for drug importing?
Importing carries some of the harshest penalties in Canadian criminal law. For Schedule I substances (cocaine, heroin, fentanyl), the maximum is life imprisonment. The mandatory minimums of one year — rising to two years where aggravating factors were present, like importing for trafficking purposes or acting with a criminal organization — were repealed by Bill C-5 in 2022.
Even importing smaller quantities of less serious drugs can lead to substantial jail time.
Defences and consequences
What are some defences to drug charges?
There are many ways to fight a drug charge. The right defence depends on the facts, but the most effective approaches challenge an illegal search, a bad warrant or wiretap errors, a denial of the right to counsel, the Crown’s proof of knowledge and control, or the lab analysis, and in some cases raise entrapment. Each is explained in the defences above. Learn more about your right to a lawyer after arrest.
What happens beyond the criminal case?
A drug conviction does not end when you leave the courtroom. The collateral damage can be worse than the sentence itself:
- A permanent criminal record in the national CPIC database, visible on every background check.
- Immigration problems — non-citizens can be found inadmissible and deported. Even permanent residents can face removal for serious drug convictions.
- Difficulty finding work, especially in industries that run criminal record checks.
- A lifetime ban from entering the United States — even a simple possession conviction can trigger this.
- Loss of professional licences or certifications in regulated fields.
- Property forfeiture — the Crown can seize assets it believes are proceeds of crime or were used in drug offences.
- Consequences in family court, including custody and access disputes.
