Ottawa will introduce a bill that is expected to reduce barriers to opening and operating supervised drug-consumption sites in Canada. The move comes after B.C. announced it would open several “overdose prevention sites” without federal approval as an emergency measure to counter the province’s highest death toll on record due to illicit drugs. As well, carfentanil – a powerful synthetic opioid more toxic than fentanyl – has now been detected in three provinces and is beginning to fuel another surge in overdoses, creating a new sense of urgency.
