On December 12, 2022, Ontario published Regulation 559/22: Naloxone Kits (Regulation), which provides the following additional information about the naloxone kit requirements. 

Naloxone (pronounced na-LOX-own) is a fast-acting drug used to temporarily reverse the effects of opioid overdoses. Naloxone can restore breathing within 2 to 5 minutes. An employer that becomes aware, or ought reasonably be aware, of a risk of worker opioid overdose, where the worker performs work for the employer, will be required to provide naloxone kit(s), maintain kit(s), and ensure training on the administration of naloxone. 

Every naloxone kit must be used, stored and maintained in accordance with the manufacturer’s instructions. The contents of each naloxone kit must be kept in a hard case. The contents of each naloxone kit must be for a single use and promptly replaced after such use. The contents of each naloxone kit must not have expired. The names and workplace locations of the workers who are in charge of the naloxone kit in the workplace and who have received training to recognize an opioid overdose and administer naloxone must be posted in a conspicuous place in the vicinity of the kit where their names and workplace locations are most likely to come to the attention of other workers. The Regulation also prescribes the contents for both a nasal spray naloxone kit and an injectable naloxone kit.
