Health Canada agreed to review the prescription-only status of naloxone, an antidote used to treat heroin and other opioid overdoses, CBC News reported.
A number of provinces have called for naloxone to be easier to access, with the idea being to treat the therapy like EpiPens and insulin so it can be on hand if needed.
"In the event Health Canada's initial assessment finds that the benefits of expanding access appear to outweigh potential risks, the next step would be a public consultation," the department said in the release, adding that the full process could be completed in about 18 months.
In April 2014, the FDA approved an easy-to-use device that injects naloxone, which is also as Narcan.
To date, a number of provinces and cities, including Edmonton, Alberta and Toronto, have already started programs in which they give out "rescue" kits containing naloxone and syringes to opioid users or their families and friends.
