Durham regional police tell 680 NEWS three people have died of suspected drug overdoses on Friday morning.
Two of the men, one in his 30s and one in his 40s, were found in the same apartment in Ajax, Ont.
One of the victims, a man in his 20s, fatally overdosed at a home in Bowmanville.
Police say the drug involved was thought to be cocaine but is now believed to have been laced with the risky opioid fentanyl and are asking anyone who recently bought street drugs to not use them due to the possibility of an overdose. Police say drugs were involved in all three deaths.
Tudos said that a recent spike in drug overdoses is a concern to Durham police, as well as other police services in the GTA.
Police in York Region were also called to a residence in Vaughan just northwest of Toronto for yet another suspected overdose case.
Frontline supervisors and special units carry naloxone kits, which contain a drug that temporarily reverses an opioid overdose, Tudos said.
"You never know what type of drugs are going to be mixed and what you're buying", he said, adding that there's no specific type of drug user that has emerged as predominantly at risk of overdose.
Police say that both the man and the woman were initially reported to be unconscious, however they were in a semi-conscious state when officers arrived on scene. Police were called there at 3:45 a.m.
Durham police say they've seen four fatal overdoses and 12 non-fatal overdoses in the region over the past two weeks alone.
In light of the overdoses, officials in Toronto have vowed to speed up the opening of three planned safe injection sites and look at purchasing naloxone in bulk to get it into the hands of more people.
