Haye said while city police are aware of other places in Canada where cocaine has been cut with fentanyl, he believes it's the first time the practice has been seen in Saskatoon.
"We're seeing, as of Saturday, it's another thing and you can't trust a drug dealer, that's what it comes down to", Davies said. "We believe we have the right people in custody".
Police had initially warned anyone who may have purchased cocaine from a drug dealer named "Lil Joe" or "Joe Bro" or have contacted a dealer with the number 306-881-7300, that the drug they purchased could be laced with fentanyl.
Police in Saskatoon have arrested three people after two overdose deaths on the weekend from cocaine allegedly laced with fentanyl.
Police say they executed four search warrants at two adjacent apartment complexes and one other Barrie residence on Friday. "A lot the time with drugs that are on the street, it's usually a mixture of pretty much anything", he said. So, we believe we have the right people in custody.
"Why they do it, I can speculate it, but I'm not sure", he said.
Six men and four women are now facing drug-related charges, including possession and intent to traffic drugs.

He says that package was brought into the kitchen where it detonated, killing a 17-year-old boy and injuring the woman. Anthony Stephan House, 39, was killed March 2 when a package exploded at his northeast Austin home, KEYE reports.
Officers say they won't pursue possession charges if you bring in product purchased from this person.
"When the major crime unit has completed (their) investigation, they'll share their findings with the provincial Crown and the federal Crown". "If it's recommended by them to proceed with the charges in relation to the death, we'll certainly follow through with that".
Police took the unusual step of releasing the street name and phone number of an alleged drug dealer in the hope of preventing further casualties. However, he said the move came after consulting with prosecutors.
"We believe that the public-safety interests are of the greater need here", he said.
Haye urged people not to use street drugs, but acknowledged not everyone would follow that advice.
Haye stressed anyone who believes they or someone they are with is experiencing an overdose should call 9-1-1. "We're only interested in the health and safety of the public", he said.
