Mississauga – The Canada Border Services Agency (CBSA) is committed to disrupting the flow of precursor chemicals into Canada and preventing harm to our communities. Between the months of June and July 2023, the CBSA at Toronto Pearson International Airport Commercial Operations District intercepted over 3.3 tonnes of PMK ethyl glycidate and 1,4-butanediol arriving from Asia. The substances were found in multiple separate shipments examined by border services officers.These chemicals are used to manufacture MDMA (ecstasy) and drugs used to commit physical and sexual assault, which are part of a group of psychoactive drugs. They act on the central nervous system and can cause changes in mood, awareness, and behavior. The interception of these chemicals has prevented millions of doses of MDMA and other drugs from reaching Canadian communities.
