None of the executives who were implicated in the so-called ORNGE air ambulance scandal will be facing criminal charges.
The OPP says they failed to find sufficient evidence to lay criminal charges, following a six-year investigation.
The probe was launched back in 2012, when allegations surfaced, of kickbacks and criminal wrongdoing on the part of senior employees at ORNGE air ambulance service, including then CEO Chris Mazza.
There were reports at the time that indicated ORNGE overpaid for helicopters supplied by an Italian company, and that some of the money was funneled back to a private firm controlled by Mazza.
The Italian company has long denied any wrongdoing.
Investigators went through thousands of documents and emails, and interviewed almost 60 people in Canada, the U.S. and Italy.
In a report released Thursday, police say that a lack of transparency in business records and lack of cooperation by key witnesses prevented them from making an evidence-based finding on what really happened.
The OPP say they considered charges of fraud, breach of trust and misappropiation of funds in the investigation.
