Drug Charges in Alberta: What You're Actually Facing

Drug prosecutions in Canada rest on a different kind of evidence than most criminal cases. The Crown's case is largely the product of police investigative work (search warrants, vehicle stops, wiretap authorizations, confidential informants, sniff-dog searches, and digital forensics) rather than the account of a civilian witness. The case is what the police found and how they found it. That makes the lawfulness of the investigation a question in its own right, separate from the question of what the substance is.

This page explains several things:

• the framework of the Controlled Drugs and Substances Act (CDSA);
• how the Cannabis Act reshaped possession law after 2018;
• what the Crown must prove for possession, trafficking, importing, and production charges;
• the Charter framework that governs whether seized drugs are admitted;
• the sentencing changes that followed Parliament's Bill C-5 in 2022; and
• the 2026 amendment to the CDSA's diversion provision for simple possession.

KJR Law represents people facing drug charges across Calgary and Southern Alberta.

Before You Give a Statement or Consent to a Search

You may be arrested or detained by police, the RCMP, or an ALERT integrated team in connection with a drug investigation. If so, you have the right to speak with a lawyer in private and without delay. You can do that before you decide whether to say anything. You are not required to answer questions or give a statement.

If police contact you without arresting or detaining you, you can still call a lawyer before you respond. Some of the most consequential decisions in a drug file can come early, before charges are formally laid.

You are also not required to consent to a search of your home, your vehicle, or your phone, and you are not required to provide the passcodes to your devices. Consent can waive Charter protections that would otherwise be available to challenge a search later. Much of a drug prosecution turns on what the police seized and how. The choices made in the first hours (whether to talk, whether to consent, whether to unlock a phone) can shape the whole file. A short call to a lawyer is a sensible first step.

The Controlled Drugs and Substances Act

The CDSA classifies controlled substances into schedules. The schedule of the substance, not just the underlying conduct, drives sentencing exposure:

• Schedule I. Cocaine, heroin, fentanyl, methamphetamine, opioids, MDMA. The most serious tier.
• Schedule II. Cannabis was removed from the CDSA when the Cannabis Act came into force in October 2018, and cannabis offences are now prosecuted under that statute. Schedule II now lists synthetic cannabinoids.
• Schedule III. LSD, psilocybin and psilocin (psychedelic mushrooms), mescaline, methylphenidate.
• Schedule IV. Prescription drugs including benzodiazepines, barbiturates, and anabolic steroids.
• Schedules V and VI. Part 1 of Schedule V temporarily lists a small number of further controlled substances. Part 2 of Schedule V and all of Schedule VI list precursor chemicals used to produce controlled substances (s. 2(1)).

The Four Principal Offences

The CDSA creates four principal offences, each with its own elements and sentencing range:

• Possession (s. 4(1)). The simple-possession prohibition reaches substances in Schedules I, II, and III.
  • Schedule I possession is hybrid. On indictment the maximum is seven years. On summary conviction it is a fine of up to $1,000, six months' imprisonment, or both for a first offence, and up to $2,000, one year, or both for a subsequent offence.
  • Schedules II and III carry lower indictable maximums: five years less a day and three years.
  • Schedule IV possession is not an offence under s. 4(1). Schedule IV substances are reached by the trafficking, import/export, and production provisions, and by s. 4(2), which covers obtaining a substance from a practitioner without disclosing prescriptions obtained from other practitioners in the preceding 30 days.
• Trafficking (s. 5(1)). "Traffic" is defined broadly in s. 2(1), not limited to commercial sale. It covers:
  • selling, administering, giving, transferring, transporting, sending, or delivering a substance;
  • selling an authorization to obtain it; and
  • offering to do any of those things.
  The offence also reaches a substance the person represents or holds out to be a controlled substance, whatever it actually is. Maximums by schedule: Schedules I and II, life imprisonment; Schedules III and V, hybrid with a ten-year indictable maximum; Schedule IV, hybrid with a three-year indictable maximum.
• Possession for the purpose of trafficking (s. 5(2)). Possession plus the purpose of trafficking, with the same penalties as trafficking. The "represented or held out" extension in s. 5(1) does not apply here: the substance itself must be a controlled substance.
• Importing, exporting, and production (ss. 6 and 7). For Schedule I and II substances, importing, exporting, possession for the purpose of exporting, and production each carry a maximum of life imprisonment. Lower tiers apply to the other schedules. Importing and exporting also reach Schedule VI precursors.

Criminal Code charges can accompany CDSA charges:

• conspiracy to traffic under s. 465;
• possession of property or proceeds obtained by crime under s. 354;
• laundering proceeds of crime under s. 462.31;
• weapons offences where firearms were present; and
• for conduct on or after July 18, 2026, the new offence in s. 169.1. It applies where a person in a position of trust, power, or authority towards someone under 18, knowing that the young person is under 18 or reckless as to that fact, recruits, counsels, encourages, or invites that young person to be a party to an offence under the Criminal Code or the CDSA, and the young person later becomes a party to that offence or a related offence. Anyone 18 or older is considered to be in that position. The offence is hybrid, with a five-year maximum on indictment.

Cannabis After 2018

The Cannabis Act legalized possession of cannabis in Canada for adults, subject to defined limits. In Alberta, adults aged 18 and over may possess up to 30 grams of dried cannabis (or equivalent) in public. Conduct that remains criminal under the Cannabis Act includes:

• possession over the legal limits (s. 8);
• distribution outside the legal retail framework (s. 9);
• distribution to a person under 18;
• possession for the purpose of selling outside the licensed regime; and
• cultivation beyond four plants per dwelling.

The maximum penalty for the more serious Cannabis Act offences is 14 years' imprisonment. Cannabis prosecutions today are about non-compliance with the legalized regime, not about cannabis itself.

What the Crown Must Prove

For a possession charge, the Crown must prove three elements beyond a reasonable doubt. The framework comes from Beaver v The Queen, [1957] SCR 531 and was restated in R v Morelli, 2010 SCC 8:

1. Knowledge. The accused knew of the existence and nature of the substance.
2. Control. The accused had control over the substance. "Possession" in the CDSA has the meaning in s. 4(3) of the Criminal Code. That includes personal and constructive possession, and joint possession where one person has the substance with the knowledge and consent of the others.
3. Identity. The substance is in fact a controlled substance. Identity is proved by a certificate or report of an analyst designated under the CDSA (s. 51) or by expert evidence. The defence can seek leave to cross-examine the analyst (s. 51(2)).

For possession for the purpose of trafficking, the Crown must also prove that the accused possessed the substance for the purpose of trafficking in it. For trafficking itself, the Crown must prove the act of trafficking or an offer to traffic. Under s. 5(1), that can include a substance the accused held out as a controlled substance.

The purpose of trafficking can be proved circumstantially, for example through:

• a quantity inconsistent with personal use;
• packaging in distribution-sized portions;
• scales and score sheets;
• cash in particular denominations; and
• expert evidence from a police officer trained in drug-trafficking investigation.

Each of those inferences can be tested.

Section 8 and the Lawfulness of the Investigation

A drug prosecution can turn on the lawfulness of the investigation as much as on what the substance was. The Charter questions that arise include the following.

Search warrants. CDSA search warrants are issued under s. 11 of the CDSA. The justice must be satisfied that there are reasonable grounds to believe the items sought are in the place to be searched. The warrant is granted ex parte on the strength of an Information to Obtain ("ITO") sworn by the investigator.

The warrant can be challenged. On review, the question is not whether the reviewing judge would have issued it, but whether, on the record before the issuing justice, with misleading information excised and amplified only to correct good-faith errors, it could have issued (R v Garofoli, [1990] 2 SCR 1421; R v Morelli, 2010 SCC 8). Overstated facts, omitted material information, and uncorroborated tips all bear on that question.

If the warrant could not have issued, the search was unlawful. The seized evidence may then be excluded under s. 24(2) of the Charter, if admitting it would bring the administration of justice into disrepute (R v Grant, 2009 SCC 32).

Wiretap authorizations. Authorizations to intercept private communications under Part VI of the Criminal Code carry requirements an ordinary search warrant does not. These include investigative necessity under s. 186(1)(b): other investigative procedures have been tried and have failed, are unlikely to work, or are impractical because of urgency.

That requirement does not apply where the offence is alleged to have been committed for the benefit of, at the direction of, or in association with a criminal organization (s. 186(1.1)). The Garofoli framework governs review of the authorization and its supporting affidavit.

Investigative detention and vehicle stops. Police powers to detain short of arrest are circumscribed. R v Mann, 2004 SCC 52 requires reasonable grounds to suspect a clear nexus between the person and a recent or ongoing crime.

A stop under provincial traffic legislation for highway-safety purposes does not require individualized suspicion. Turning that stop into a drug investigation, by detaining or searching for that purpose, needs its own lawful basis. Where a detention does not meet the standard, the search, the seizure, and any statements that follow can be challenged.

Sniff-dog searches. Under R v Kang-Brown, 2008 SCC 18 and R v MacKenzie, 2013 SCC 50, a sniff-dog deployment requires reasonable suspicion grounded in articulable facts. A deployment based on a hunch does not meet that standard.

Searches of phones and digital devices. R v Vu, 2013 SCC 60 requires specific prior authorization to search a computer or phone. A warrant to search a place does not, on its own, authorize a search of the devices found there.

R v Fearon, 2014 SCC 77 permits only a limited search of a phone incident to a lawful arrest, and only where the search is:

• truly incidental to the arrest;
• tailored to its purpose; and
• recorded in detailed notes.

A broader search requires a warrant.

Confidential informants. Informer privilege protects an informant's identity, but the tip itself is reviewable. Under Garofoli, a tip relied on in support of a warrant is assessed on the totality of the circumstances. That means how detailed it was, the source of the informant's knowledge, and the indicia of the informant's reliability, including corroboration.

Sentencing After Bill C-5

Drug sentencing in Canada changed substantially in 2022, when Bill C-5 came into force. Four points matter for sentencing today.

• No CDSA minimum sentences. Bill C-5 repealed the mandatory minimum sentences the CDSA had prescribed for trafficking, possession for the purpose of trafficking, importing and exporting, and production.
  • Before that repeal, R v Lloyd, 2016 SCC 13 had struck down the one-year minimum for trafficking or possession for the purpose of trafficking by an offender with a prior designated substance conviction in the previous ten years.
  • The CDSA as it now reads prescribes no minimum punishment for any offence. The 2026 individualized exception to minimum sentences in s. 718.4 of the Criminal Code therefore has nothing to attach to on a CDSA charge.
  • Parliament's 2026 affirmation of minimum sentences (S.C. 2026, c. 19, s. 87) reaches only minimums still in a statute, so it does not bring back the repealed CDSA minimums.
  Sentencing proceeds on the ordinary principles of proportionality and individualization, and non-custodial dispositions are available.
• Conditional sentences. A conditional sentence is imprisonment of less than two years served in the community on strict conditions. Before 2022, s. 742.1 barred one for offences prosecuted by indictment with a 14-year or life maximum, and for ten-year offences prosecuted by indictment involving the import, export, trafficking, or production of drugs. Bill C-5 repealed those bars.
  • The court must be satisfied that serving the sentence in the community would not endanger the community and would be consistent with the fundamental purpose and principles of sentencing (s. 742.1(a)).
  • A conditional sentence is still unavailable for a criminal organization offence prosecuted by indictment with a maximum of ten years or more (s. 742.1(d)).
  • The 2026 amendments to s. 742.1 (offences on or after July 15, 2026) add bars for listed sexual offences, and none of them reaches a CDSA offence.
• Discharges. Because no CDSA offence carries a minimum, a discharge under s. 730 of the Criminal Code can be considered for simple possession and for the lower-tier trafficking, importing, and production offences. It is not available for an offence punishable by life imprisonment (s. 730(1)). That covers Schedule I and II trafficking, possession for the purpose of trafficking, importing, exporting, and production.
• Diversion for simple possession. Part I.1 of the CDSA (ss. 10.1–10.7), added by Bill C-5, sets out principles for simple possession under s. 4(1). They include that problematic substance use should be addressed primarily as a health and social issue (s. 10.1).
  • Police (s. 10.2). Instead of laying a charge, a peace officer must consider whether it would be preferable to take no further action, to warn the person, or, with the person's consent, to refer them to a program or service provider (s. 10.2(1)). A failure to consider those options does not invalidate a charge that is later laid (s. 10.2(2)).
  • Prosecutors (s. 10.3). Section 10.3 limits prosecution. A s. 4(1) prosecution may be commenced or continued only if the prosecutor is of the opinion, having regard to the s. 10.1 principles, that a warning, a referral, or alternative measures would not be appropriate, and that a prosecution is appropriate in the circumstances.
  • The 2026 change. Since July 18, 2026, the alternative measures s. 10.3 refers to are those defined in s. 715.44 of the new Part XXII.2 of the Criminal Code (S.C. 2026, c. 19, s. 92). The wording of the limit is otherwise unchanged from 2022.
  • Evidence (s. 10.5). Evidence that a person received a warning or referral, or that police took no further action, is not admissible to prove prior offending.
  • Records (s. 10.6). A simple-possession conviction entered after November 17, 2022 is kept separate and apart from other conviction records two years after the conviction or the end of the sentence, whichever is later. The person is then deemed never to have been convicted of that offence.

Aggravating factors specific to drug offences are codified in s. 10(2) of the CDSA. On a conviction for a designated substance offence (any Part I offence other than simple possession), the court must consider any relevant aggravating factor, including that the person:

• carried, used, or threatened to use a weapon;
• used or threatened violence;
• trafficked, or possessed for the purpose of trafficking, in or near a school or another public place usually frequented by people under 18;
• trafficked, or possessed for the purpose of trafficking, to a person under 18;
• had a prior conviction for a designated substance offence or a designated Cannabis Act offence; or
• used or involved a person under 18 in the offence.

If the court finds one of these factors established but decides not to impose imprisonment, it must give reasons (s. 10(3)).

The Criminal Code adds two general provisions:

• Involving a person under 18. Section 718.2(a)(ii.2) makes it an aggravating circumstance that the offender involved a person under 18 in the offence. Since July 18, 2026, it also expressly covers counselling a person under 18 (S.C. 2026, c. 19, s. 62).
• Criminal organizations. For an offence committed for the benefit of, at the direction of, or in association with a criminal organization, s. 718.2(a)(iv) treats that as aggravating. Since July 15, 2026, s. 718.07 also directs the court to give primary consideration to denunciation and deterrence. Parliament has directed that s. 718.07 applies to matters ongoing on that date.

Whether the 2026 changes can apply to an offence committed before they came into force may be contested.

Drug Treatment Court in Calgary

Calgary's Drug Treatment Court (DTC) is a problem-solving court for people whose offending is driven by addiction to a Schedule I drug such as cocaine, opioids, or methamphetamine. It may be available for non-violent offenders. Section 10(4) of the CDSA allows a sentencing court to delay sentencing so the offender can take part in a drug treatment court program approved by the Attorney General.

Entry is voluntary and has its own eligibility criteria. It requires a guilty plea, a commitment to treatment, and Crown consent. The program involves court-supervised treatment, regular drug testing, and judicial review.

Completing the program can lead to a non-custodial sentence where custody would otherwise be imposed. Whether DTC fits a particular file is a question to assess early.

The Consequences Beyond the Sentence

A drug conviction carries consequences beyond the sentence itself, and they fall into two distinct categories. The first are ancillary orders the court imposes as part of the sentence itself. Each has its own statutory test, and each is open to submissions at sentencing:

• Asset forfeiture. Under s. 16 of the CDSA, on a conviction (or a discharge, where one is available) for a designated substance offence and on the Attorney General's application, the court must order forfeiture of offence-related property it is satisfied, on a balance of probabilities, is related to the offence.
  • Under s. 19.1(3), the court may decline to forfeit real property where the impact would be disproportionate to the offence, its circumstances, and the person's record.
  • Criminal Code Part XII.2 (s. 462.37 and following) governs forfeiture of proceeds of crime.
  • For CDSA ss. 5–7 offences prosecuted by indictment, s. 462.37(2.01) also allows forfeiture of property the Attorney General identifies, where the court finds a pattern of criminal activity for material benefit in the previous ten years, or income from legitimate sources that cannot account for the offender's property. The offender can show, on a balance of probabilities, that particular property is not proceeds of crime (s. 462.37(2.03)).
  Vehicles, cash, real estate, and electronic devices can all be subject to forfeiture orders.
• DNA orders. Trafficking, possession for the purpose of trafficking, importing and exporting, and production are secondary designated offences under s. 487.04 of the Criminal Code. For an order to be made, the offence must be prosecuted by indictment and carry a maximum of five years or more, so the three-year Schedule IV variants are not included. A DNA order on a secondary designated offence is discretionary, not automatic.
  • The Crown applies under s. 487.051(3), and the court may make the order if satisfied that it is in the best interests of the administration of justice.
  • The court must consider the person's criminal record, the nature of the offence and the circumstances of its commission, and the impact on the person's privacy and security of the person. It must give reasons.
  • The defence makes submissions against the order.
• Weapons prohibitions. A conviction (or a discharge, where one is available) for trafficking, possession for the purpose of trafficking, importing, exporting, possession for the purpose of exporting, or production triggers a mandatory prohibition order under s. 109(1)(c) of the Criminal Code. This applies whatever the schedule and whichever way the Crown proceeded. The equivalent Cannabis Act offences are covered by s. 109(1)(c.1).
  • First order. It prohibits non-restricted firearms, crossbows, restricted weapons, firearm parts, ammunition, and explosive substances until at least ten years after release from imprisonment (or after the conviction or discharge, if there is no imprisonment). It prohibits prohibited and restricted firearms, prohibited weapons and devices, and prohibited ammunition for life.
  • Later orders. A subsequent order is for life.
  • Other drug offences. For any other drug offence, such as simple possession, the court must consider a discretionary order under s. 110 only where violence against a person was used, threatened, or attempted, or where the offence involved a firearm, weapon, ammunition, or explosive substance.

The second category are consequences that flow from the conviction but are not imposed by the criminal court. They arise under other regimes that the sentencing judge does not control:

• Immigration consequences. For a non-citizen, including a permanent resident, a drug conviction can lead to inadmissibility under the Immigration and Refugee Protection Act.
  • For a permanent resident, serious criminality covers a conviction for an offence punishable by a maximum of at least ten years, or one for which more than six months' imprisonment is imposed.
  • The length of the sentence can also affect whether there is a right of appeal against removal.
  • Hybrid offences are treated as indictable for these purposes even when the Crown proceeds summarily.
  The immigration consequences of a plea or a sentence should be assessed before either is finalized.
• U.S. travel. Admissibility to the United States is governed by U.S. law, not by how an offence is classified or prosecuted in Canada, and U.S. immigration law treats controlled-substance matters seriously. Anyone who travels to the United States should get advice on U.S. law before resolving a drug charge.
• Professional consequences. Regulators in healthcare, education, financial services, and other professions may treat a drug conviction as a disciplinary or licensing matter.

Speak to a Lawyer Before You Speak to Police.

Drug investigations move quickly at the outset. The early decisions (whether to provide a statement, whether to consent to a search, whether to provide passwords) can shape the rest of the file. You may have been charged with a drug offence, or contacted by police, the RCMP, or an ALERT integrated team in connection with a drug investigation. Either way, a conversation with a lawyer is a useful first step.
