OSHAWA, Ont. -- Police say a woman is alive after officers administered an antidote to reverse a suspected fentanyl overdose.

Durham regional police say they were called to assist paramedics at an Oshawa, Ont., apartment last Friday evening and found a woman without vital signs.

They say officers quickly administered naloxone spray and CPR and were able to revive the 23-year-old.

Police say the woman was taken to hospital.

Investigators say they believe she had consumed fentanyl, a synthetic opioid prescribed for patients with chronic pain.

About 2,000 people died from opioid overdoses across Canada in 2015.
