Ontario's medical regulator approves changes to prescribing safer supply drugs

Ontario's medical regulator, The College of Physicians and Surgeons of Ontario (CPSO), approved significant changes to how doctors prescribe safer supply drugs on October 13, 2026. These medications are given to people at high risk of overdose as an alternative to illicit opioids. The CPSO board voted to implement three main measures: requiring physicians to only prescribe safer supply medications in conjunction with opioid agonist treatment; mandating monthly comprehensive in-person clinical assessments for patients receiving these medications; and necessitating that the medication be consumed under physician supervision, eliminating “carries” (prescriptions taken home).

Some experts argue that this move will lead to better oversight of prescribing practices, while others fear it might push high-risk users towards more dangerous street drugs like fentanyl. Hydromorphone, a potent opioid about five to ten times stronger than morphine, is one such drug being regulated under these changes. The shift aims to reduce the diversion of safer supply opioids into illicit markets but raises concerns for those who do not respond well to opioid agonist therapy and might lack effective alternatives.
