“Investigators believe that at least three deaths and one overdose is connected to fentanyl,” police said.

Fentanyl is a potent opioid.

According to the United States Drug Enforcement Administration, it is around 100 times more potent than morphine and 50 times more potent than heroin as a pain relief drug.

York Regional Police said it can be mistaken for other, weaker opioids like morphine or heroine, which can lead to an overdose.

Anyone who exhibits signs of an overdose should call 911 immediately, officers said.
