Controlled Drugs and Substances Act: Offenses and Penalties

Canada’s Controlled Drugs and Substances Act creates four main offenses and penalties: possession, trafficking, importing or exporting, and production. The sentence you face depends on which offense is charged and which schedule the drug falls under, and the numbers span an enormous range. A first-time summary conviction for simple possession can mean a $1,000 fine; trafficking, importing, or producing a Schedule I or II substance like heroin, fentanyl, or cocaine can mean life imprisonment. Since November 2022, every mandatory minimum sentence under the Act has been repealed, so judges now have full discretion between zero and the statutory maximum.

Why the Schedule Matters

The CDSA sorts regulated substances into nine schedules, and the schedule is the single biggest driver of any penalty. Schedule I is the most serious tier and contains heroin, cocaine, fentanyl and its analogues, oxycodone, morphine, and methamphetamine.¹ Schedule II covers synthetic cannabinoids. Schedule III includes hallucinogens and certain stimulants such as LSD, psilocybin, mescaline, DMT, and methylphenidate.² Schedule IV covers barbiturates, benzodiazepines like alprazolam and diazepam, and anabolic steroids.³ Schedules V and VI regulate precursor chemicals used to make illegal drugs.⁴

Natural cannabis is no longer regulated under the CDSA. It moved to the Cannabis Act in 2018, so cannabis offenses are not addressed here.

The Four Offenses

Possession (Section 4)

Section 4 makes it a crime to possess any controlled substance without authorization. The Crown has to prove both physical control over the substance and knowledge of what it is. You can be in possession without the drugs being on your person. Holding them for someone else, or keeping them somewhere you control such as a car or a locker, is enough.⁵

Trafficking (Section 5)

Section 5 covers trafficking and possession for the purpose of trafficking. No completed sale is required. Offering to give, sell, or distribute a controlled substance is itself trafficking, even if nothing changes hands. Prosecutors look to indicators like quantity, scales, packaging materials, large amounts of cash, and messages suggesting distribution to show that possession was for the purpose of trafficking rather than personal use.⁶

Importing and Exporting (Section 6)

Section 6 prohibits moving any controlled substance across an international border without authorization, and it also covers possessing a substance for the purpose of exporting it. Every scheduled substance is covered, regardless of quantity.⁷

Production (Section 7)

Section 7 targets manufacturing, synthesizing, cultivating, or harvesting a controlled substance. Providing equipment or chemicals used in production can also lead to a charge. Grow operations, clandestine labs, and pill press setups are typical production cases.⁸

Penalties by Offense and Schedule

Most offenses can be prosecuted either as indictable offenses (more serious, higher maximums) or by summary conviction (faster, lower maximums). The exception is trafficking, importing, exporting, and producing Schedule I or II drugs, where there is no summary conviction route.

Possession

Possession carries the lowest maximums, but even here the schedule changes the outcome dramatically.

Schedule I substances (heroin, cocaine, fentanyl, and so on): up to 7 years on indictment. On summary conviction, a first offense is punishable by a fine of up to $1,000 or 6 months in jail, or both; a subsequent offense, up to $2,000 or 1 year, or both.⁵
Schedule II substances (synthetic cannabinoids): up to 5 years less a day on indictment. Summary conviction penalties match Schedule I.⁵
Schedule III substances (LSD, psilocybin, and so on): up to 3 years on indictment, with the same summary conviction penalties.⁵

A first-time summary conviction for Schedule I possession can still include jail time. It is not just a fine on the table.

Trafficking

Trafficking penalties jump sharply.

Schedule I or II: life imprisonment as an indictable offense. No summary conviction option.⁶
Schedule III or V: up to 10 years on indictment, or up to 18 months on summary conviction.⁶
Schedule IV: up to 3 years on indictment, or up to 1 year on summary conviction.⁶

Importing, Exporting, and Production

These offenses carry the same maximums as trafficking. Schedule I or II conduct is punishable by life imprisonment. Schedule III and V offenses carry a maximum of 10 years on indictment, and Schedule IV offenses cap out at 3 years.⁷⁸

What Pushes a Sentence Up

Section 10 states that the purpose of sentencing under the CDSA is to maintain a safe society while encouraging rehabilitation and, where appropriate, treatment.⁹ The same section then lists aggravating factors a court must consider:

Carrying, using, or threatening to use a weapon during the offense.¹⁰
Using or threatening violence in connection with the offense.
Trafficking near a school or a place frequented by minors, trafficking directly to someone under 18, or using someone under 18 to commit the offense.¹⁰
A prior conviction for a designated substance offense under the CDSA or a designated offense under the Cannabis Act.

If one or more of these factors is present and the court still chooses not to impose a prison sentence, the judge must put reasons for that decision on the record. Quantity, the offender’s role in the operation, and criminal organization involvement also feed into the sentence under general Criminal Code principles.⁹

Mandatory Minimums Are Gone

Until November 2022, several CDSA offenses carried mandatory minimum sentences. Bill C-5 repealed every one of them. The repealed minimums had applied to trafficking and possession for the purpose of trafficking (1 and 2 years), importing and exporting (1 and 2 years), and production of Schedule I or II substances (ranging from 18 months to 3 years depending on the circumstances).¹¹

Parliament pointed to evidence that the minimums disproportionately affected Indigenous peoples, Black Canadians, and other marginalized communities. The practical effect for sentencing today is that judges have discretion all the way from a non-custodial sentence up to the statutory maximum. The ceilings have not moved. Life imprisonment remains available for trafficking, importing, exporting, and producing Schedule I or II substances, and the section 10 aggravating factors still apply.

Calling 911 During an Overdose

One scenario sits outside the usual exposure to a possession charge. The Good Samaritan Drug Overdose Act, in force since 2017, writes a limited immunity into the CDSA. If you seek emergency help because someone is overdosing, you cannot be charged with simple possession based on evidence discovered as a result of that call. The protection covers everyone at the scene when responders arrive, including the person who overdosed.¹²

It goes further than blocking new charges. If you are on probation, parole, or pre-trial release with conditions tied to a possession offense, those conditions are deemed not breached because you sought help or were present at the overdose scene.¹²

The immunity is limited to section 4(1) possession. It does not shield trafficking, production, or more serious charges that the evidence might also support.

After a Conviction

Record Suspensions

A CDSA conviction can be addressed later through a record suspension from the Parole Board of Canada, formerly called a pardon. You cannot apply until every part of your sentence is finished, including fines, custody, conditional sentences, parole, and probation. A waiting period then runs:¹³

Summary conviction offenses committed on or after March 13, 2012: 5 years from completion of the sentence.
Indictable offenses: 10 years from completion of the sentence.

If your first offense was committed on or after March 13, 2012, you may be ineligible if you have been convicted and sentenced to two or more years of imprisonment for more than three indictable offenses. Where court records do not confirm whether a matter proceeded by indictment or summarily, the Parole Board applies the longer 10-year waiting period by default.¹³

Crossing Into the United States

A Canadian drug conviction creates a separate problem at the U.S. border. U.S. immigration law generally treats drug convictions as making a person inadmissible, and even a simple possession conviction with no jail time can trigger a denial of entry. A Canadian record suspension does not fix it, because U.S. Customs and Border Protection keeps its own records and does not recognize foreign pardons.

Entry with a drug conviction typically requires a Form I-192 waiver, the Application for Advance Permission to Enter as a Nonimmigrant. You will need an official court record for every conviction, a signed personal statement explaining what happened, evidence of rehabilitation such as counselling or employment history, and an RCMP criminal record check dated within 15 months of your application. The RCMP check has to be in hand before you file. Incomplete applications are not processed.¹⁴

Applications are filed through the e-SAFE portal or at designated ports of entry. CBP asks that you wait at least 150 days before inquiring, and processing can take six months or more.¹⁴
