A drug charges lawyer in Calgary at Centobin Law Office defends individuals charged with possession, trafficking, and production offences under the Controlled Drugs and Substances Act (CDSA). These charges carry penalties ranging from fines to life imprisonment, depending on the substance and quantity. Our criminal defence team builds case-specific strategies — from challenging search warrants to negotiating reduced charges — to protect your future after a drug arrest in Calgary.
Drug possession charges in Calgary arise under Section 4(1) of the Controlled Drugs and Substances Act and require the Crown to prove knowledge and control of the substance. A drug defence lawyer in Calgary evaluates whether police can establish these elements or whether the charge can be challenged or dismissed.
Simple possession means holding a controlled substance for personal use. Possession for trafficking (PPT) under Section 5(2) of the CDSA carries significantly harsher penalties because prosecutors allege intent to distribute. Courts evaluate quantity, packaging, cash, scales, and multiple phones to distinguish between the two. The difference between a conditional discharge and years in federal custody often hinges on this classification.
If police found a small amount on your person, a possession charge is more likely. Large quantities, divided packaging, or evidence of transactions may lead the Crown to escalate to PPT — even without proof of a single sale.
Canadian law recognizes three forms of possession: personal possession (the substance is on your person or in your belongings), constructive possession (you have knowledge of and control over a substance stored elsewhere), and joint possession (you share knowledge of and control over a substance with another person). A drug possession defence lawyer in Calgary examines which form applies and whether the Crown can prove the required knowledge and control elements.
A first drug possession offence in Calgary does not automatically result in a criminal record. A skilled defence lawyer can pursue a conditional discharge, diversion program, or alternative measures — outcomes that keep your record clean.

A drug conviction — even for simple possession — can disqualify you from jobs requiring security clearance, block border crossings, and trigger immigration consequences. Read about how a criminal conviction impacts your employment before deciding to handle charges without legal representation.
Drug trafficking charges in Calgary include selling, transporting, or distributing controlled substances under Section 5 of the CDSA and carry severe penalties, including life imprisonment for Schedule I drugs. A criminal defence lawyer examines evidence such as surveillance, informants, and wiretaps to identify weaknesses in the Crown’s case.
Drug production under Section 7 covers manufacturing, synthesizing, growing, or altering any controlled substance. Operating or allowing others to operate a grow-op, meth lab, or fentanyl press on your property exposes you to production charges regardless of your direct involvement in the manufacturing process.
Trafficking a Schedule I substance (cocaine, heroin, fentanyl, methamphetamine) carries a maximum sentence of life imprisonment. If the offence occurs near a school, involves a person under 18, or is connected to organized crime, mandatory minimum sentences of one to two years apply. These are among the most serious charges in the Canadian criminal justice system.
Because trafficking charges often arise from large police operations — wiretaps, controlled buys, confidential informants — the evidence is complex but also vulnerable to procedural challenges. A Calgary drug trafficking lawyer reviews warrant applications, intercept authorizations, and disclosure packages to identify Charter violations that can suppress evidence or collapse the Crown’s case entirely.
Trafficking charges frequently overlap with proceeds of crime and money laundering allegations. Our fraud charges defence practice handles related financial offences.
If you are detained after a trafficking arrest, securing release requires a focused bail hearing process — particularly for Schedule I substances where the Crown may argue you pose a flight risk or danger to the community.
Drug schedules under the Controlled Drugs and Substances Act classify substances based on their potential for harm and determine the penalties for possession and trafficking offences in Canada. The schedule a substance falls under directly determines the maximum penalty you face. Understanding which schedule applies to your charge is the first step a drug charges lawyer in Calgary takes when building your defence.
| Schedule | Example Substances | Possession Max | Trafficking Max |
| Schedule I | Cocaine, heroin, fentanyl, methamphetamine, oxycodone | 7 years | Life imprisonment |
| Schedule II | Cannabis (above legal limits) | 5 years | Life imprisonment |
| Schedule III | Psilocybin (magic mushrooms), LSD, mescaline | 3 years | 10 years |
| Schedule IV | Barbiturates, benzodiazepines, and anabolic steroids | No standalone possession charge | 3 years (indictable) |
Schedule I offences attract the most aggressive prosecution in Calgary courts. If your charges involve fentanyl or methamphetamine — the two substances driving the most drug prosecutions in Calgary Provincial Court — the Crown often seeks custodial sentences even for first offenders.
Schedule IV substances include certain prescription medications. Charges involving these substances sometimes overlap with impaired driving charges when prescription drug use leads to driving allegations.
Penalties for drug offences in Calgary range from fines and probation to life imprisonment, depending on the substance schedule, offence type, and prior history. A drug charges lawyer in Calgary assesses these factors to determine likely sentencing outcomes and defence options before advising you on how to proceed.
For Schedule I possession (cocaine, fentanyl, heroin): the maximum sentence is 7 years imprisonment for an indictable offence. When prosecuted as a summary offence for smaller quantities, the maximum penalty is a $1,000 fine and 6 months' imprisonment for a first offence.
For Schedule II possession (cannabis above legal limits): the maximum is 5 years, indictable. Since legalization, cannabis possession charges apply only when quantities exceed limits set under the Cannabis Act.
For Schedule III possession (psilocybin, LSD): the maximum is 3 years indictable or a $2,000 fine and 1 year summary for a first offence.
Trafficking a Schedule I substance carries a maximum of life imprisonment with mandatory minimums of 1–2 years when aggravating factors are present. Production of Schedule I substances carries the same life maximum with mandatory minimums ranging from 2–3 years depending on circumstances.
Not every drug charge results in a conviction. A criminal defence lawyer in Calgary can pursue conditional discharges (Section 730 of the Criminal Code), diversion programs, peace bonds, or stayed charges — all of which prevent a permanent criminal record.

After a drug arrest in Calgary, the case proceeds through a process that includes arrest, release or detention, a bail hearing, disclosure review, and trial or resolution. Early legal representation from a drug charges lawyer in Calgary is critical to protect your rights and challenge the Crown’s evidence at every stage.
Step 1 — Arrest and Your Rights. Police will inform you of the charges, read your Charter rights, and offer access to a lawyer. Exercise your right to silence immediately — anything you say becomes evidence.
Learn how to protect your rights after an arrest in Calgary before answering any questions.
Step 2 — Release or Detention. For minor possession charges, police may release you with an appearance notice or undertaking. For trafficking or production charges, you may be held for a bail hearing within 24 hours.
Step 3 — Bail Hearing (if detained). The Crown must justify why your continued detention is necessary. A drug defence lawyer in Calgary argues for your release with or without conditions.
In trafficking cases, the bail hearing defence stage is critical because the burden of proof may shift under Section 515(6) of the Criminal Code. Most drug bail hearings in Calgary are held at the Calgary Provincial Court.
Step 4 — Disclosure and Case Review. Your lawyer receives the Crown’s evidence package and reviews police reports, lab analysis, witness statements, surveillance records, and warrant applications for weaknesses.
Step 5 — Resolution or Trial. Most drug cases resolve through negotiation — reduced charges, diversion, or withdrawal. Cases that proceed to trial at Calgary Provincial Court (summary matters) or the Court of King’s Bench (indictable matters) are decided based on whether the Crown proves every element beyond a reasonable doubt.
Every drug case has a unique fact pattern. A drug charges lawyer in Calgary evaluates how police obtained evidence, what the Crown can prove, and whether Charter rights were respected before recommending a defence strategy.
Section 8 of the Canadian Charter of Rights and Freedoms protects you from unreasonable search and seizure. If police searched your vehicle, home, or person without a valid warrant or recognized exception, the evidence they found may be excluded under Section 24(2) of the Charter. Warrantless searches during traffic stops, consent searches obtained under pressure, and searches exceeding the scope of the warrant are the most common violations a criminal defence lawyer in Calgary challenges in drug cases.
The Crown must prove you knew the substance was in your possession and that you had control over it. If drugs were found in a shared vehicle, a roommate’s belongings, or a common area, the prosecution faces a significant burden proving constructive possession. A drug defence lawyer in Calgary examines fingerprints, DNA evidence, and surveillance to assess whether the Crown can actually connect you to the substance.
Police field tests are presumptive, not conclusive. Health Canada lab analysis must confirm the substance, its weight, and its purity. Defence counsel reviews lab certificates, chain-of-custody records, and analyst qualifications. Errors in testing or gaps in the chain of custody create reasonable doubt that a drug charges lawyer in Calgary can leverage at trial or in pre-trial negotiations.
Beyond search issues, Charter violations include denial of the right to counsel (Section 10(b)), unreasonable detention, failure to provide reasons for the arrest, and entrapment by undercover officers. When a violation is established, a judge weighs whether admitting the evidence would bring the administration of justice into disrepute. Successful Charter applications have resulted in complete case dismissals in Calgary drug proceedings.

Not every case requires a trial. Where the evidence is strong, but circumstances are sympathetic — first offence, small quantity, addiction-related behaviour — a criminal defence lawyer in Calgary negotiates with the Crown for reduced charges, diversion programs, conditional discharges, or peace bonds. These outcomes avoid a criminal record while resolving the matter.
If your drug charges are accompanied by assault charges or other violent offence allegations, the defence strategy must address both matters simultaneously.

Yes. Drug charges can be dropped (withdrawn or stayed) if the Crown determines there is no reasonable prospect of conviction. Common reasons include Charter violations that render evidence inadmissible, weak identification of the accused, insufficient lab analysis, or successful completion of a diversion program. A drug charges lawyer in Calgary identifies and presents these weaknesses to the Crown as early as possible.
A drug conviction — including simple possession — can trigger inadmissibility under the Immigration and Refugee Protection Act (IRPA). This affects permanent residents, temporary visa holders, and citizenship applicants. Even a conditional discharge may be reported. If you hold non-citizen status, your criminal defence must account for immigration consequences from the outset.
Learn about the intersection of Canada's criminal justice and immigration systems.
A drug conviction stays on your criminal record permanently unless you obtain a record suspension (pardon). For summary conviction drug offences, you become eligible to apply 5 years after completing your sentence. For indictable offences, the waiting period is 10 years. A conditional discharge results in no criminal record after the discharge period expires.
Exercise your right to silence and contact a drug charges lawyer in Calgary before making any statement to police. Do not consent to searches of your phone, vehicle, or home beyond what police can lawfully compel. Write down everything you remember about the arrest — who was present, what was said, and how the search was conducted. Early legal representation allows your defence lawyer to preserve evidence, challenge procedural errors, and begin building your case before the Crown solidifies its position.
A first drug possession offence for a Schedule I substance carries a maximum of 7 years (indictable) or a $1,000 fine and 6 months (summary). In practice, first-time offenders in Calgary with small quantities frequently receive conditional discharges, meaning no permanent criminal record if the conditions are met. The outcome depends heavily on the substance, quantity, and quality of your legal representation.
Police cannot search your phone without a warrant in most circumstances. The Supreme Court of Canada’s decision in R v. Fearon (2014) permits limited warrantless searches incident to arrest under strict conditions, but routine phone searches require judicial authorization. If police accessed your phone without a warrant, a drug charges lawyer in Calgary can seek to have that evidence excluded.
A drug conviction appears on criminal record checks and can disqualify you from positions requiring security clearance, professional licensing, or cross-border travel. Industries including healthcare, education, finance, and transportation routinely conduct background checks.
