Drug trafficking in Canada involves the sale, distribution, or transportation of controlled substances listed under the Controlled Drugs and Substances Act (CDSA). This can include illegal drugs such as cocaine, heroin, methamphetamine, and unauthorized distribution of prescription medications like opioids. Even offering or attempting to distribute controlled substances can be considered trafficking, regardless of the quantity involved. Trafficking charges are not limited to large-scale operations—small quantities exchanged for profit or distribution can result in serious criminal charges.
