Our practice areas

Drug charges are among the most common—and most aggressively prosecuted—criminal offences in Canada. They are primarily governed by the Controlled Drugs and Substances Act (CDSA), with additional related offences found in the Criminal Code of Canada.

Convictions can lead to:

• Lengthy jail sentences
• Heavy fines
• A permanent criminal record
• Severe restrictions on employment
• Serious international travel consequences, especially to the United States

The penalties you face depend on the type of drug, the quantity involved, and the surrounding circumstances—including whether the Crown alleges trafficking, production, or organized-crime involvement.

The Controlled Drugs and Substances Act (CDSA)

The CDSA is the primary legislation regulating illegal drugs and controlled substances in Canada. It classifies drugs into schedules based on their medical use, risk of harm, and potential for abuse:

• Schedule I (most serious): Cocaine, heroin, fentanyl, methamphetamine, opioids
• Schedule II: Cannabis (now largely governed by the Cannabis Act, with limited CDSA crossover)
• Schedule III: LSD, psilocybin (magic mushrooms), mescaline
• Schedule IV: Prescription drugs such as barbiturates and benzodiazepines
• Other Schedules: Chemical precursors used to manufacture illegal drugs
  
  

The schedule classification strongly affects bail, sentencing, and trial strategy.

Common Drug Offences

The most frequently charged drug-related offences in Canada include:

• Possession
  Having a controlled substance without legal authorization.
• Possession for the Purpose of Trafficking (PPT)
  Possessing drugs with the intent to sell, give, distribute, or deliver them.
• Trafficking
  Selling, transporting, delivering, or distributing a controlled substance—even without money changing hands.
• Production
  Growing, manufacturing, or otherwise producing illegal drugs, including indoor grow operations and synthetic drug labs.
• Importing or Exporting
  Bringing controlled substances into or out of Canada—one of the most heavily penalized drug offences.
• Possession of Property Obtained by Crime (Drug-Related)
  
  Possessing cash, vehicles, or other assets alleged to be connected to drug trafficking or production.
  
  
  

Penalties and Sentencing for Drug Offences

The CDSA imposes some of the harshest penalties in Canadian criminal law, particularly for Schedule I substances and trafficking-related conduct. Examples include:

• Simple Possession (Schedule I):
  • Up to 7 years in prison by indictment
  • Or up to 1 year in jail and/or a fine on summary conviction
• Trafficking (Schedule I):
  • Maximum sentence: Life imprisonment
• Production (Schedule I):
  • Maximum: Life imprisonment
  • Mandatory minimum sentences may apply, depending on aggravating factors (some have been struck down by courts, others remain in force)
• Importing / Exporting:
  • Almost always prosecuted by indictment
  • Maximum: Life imprisonment
    
    

In addition to imprisonment, a conviction almost always results in:

• A permanent criminal record
• Asset forfeiture (cash, vehicles, homes, or property)
• Strict probation conditions
• Severe travel restrictions, especially to the United States
• Serious immigration consequences, including removal for non-citizens
  
  
  

Life Consequences of a Drug Conviction

Beyond jail, a drug conviction can permanently affect every area of your life:

• Permanent barriers to employment and professional licensing
• Loss of eligibility for certain government jobs and security-cleared work
• International border restrictions
• Damage to family relationships, housing, and reputation
• Ongoing court supervision and reporting conditions
  
  

For many people, these collateral consequences last far longer than any custodial sentence.

Drug Offences and the Criminal Code

While the CDSA governs the drug-specific offences, the Criminal Code often adds companion charges, including:

• Conspiracy to commit a drug offence
• Weapons offences connected to drug activity
• Proceeds of crime (money laundering–related allegations)
• Participation in a criminal organization
  
  

These additional charges significantly increase sentencing exposure and case complexity.

Defending Drug Charges

Drug prosecutions often rely on searches, wiretaps, informants, and long-term police surveillance. Many strong defences arise from Charter violations and evidentiary weaknesses, including:

• Whether police had lawful authority to search your home, vehicle, or phone
• Unlawful search and seizure under Charter section 8
• Whether the Crown can prove knowledge and control of the substance
• Whether alleged trafficking intent is actually supported by the evidence
• Weaknesses in undercover operations, confidential informants, and wiretap authorizations
