Hi, I’m Currents co-editor Gabe Pollock. Welcome to your weekly Peterborough Currents email newsletter!

Earlier this month came the revelation of a massive criminal corruption investigation in the Toronto police force, that found cops allegedly conspiring with drug traffickers and sharing information that facilitated shootings. Seven officers and one retired constable have been arrested, and two more officers have been suspended.

This has already led to debates about penalties for arrested officers and a provincewide review of corruption in policing, so it seemed like the perfect time to look back at recent incidents of alleged police criminality right here in Peterborough.

Three Peterborough Police officers arrested on criminal charges in the last two years

by Gabe Pollock

Since 2024, there have been three Peterborough Police officers arrested on criminal charges. One of these has been resolved and the other two are still before the courts, with one officer currently on paid suspension and one relegated to administrative duties. 

Peterborough Currents provides an update on all three cases and asks the police for a comment.

Mackenzie Rogers 

Following a six-month investigation, Constable Mackenzie Rogers was arrested by the Ontario Provincial Police in September 2024. He was charged with possession of property obtained by crime over $5,000 and two counts of breach of trust.

According to court documents obtained by The Peterborough Examiner, Rogers allegedly shared undisclosed “sensitive” police information on two occasions, almost a year apart, and was in possession of a stolen vehicle for most of 2023. 

Rogers is a seven-year veteran of the force, having served as a special constable at the Peterborough courthouse and, most recently, as a constable in the Community FIRST unit, which deals with property crimes in town.

A statement by Peterborough Police Chief Stuart Betts at the time of the arrest said, “As Chief of Police, this is difficult and disappointing news to have to share with the community. I also recognize that this is an extremely difficult day for everyone in our Organization, and for the community to learn that someone in a position of trust has been arrested and charged criminally.”

Following his arrest, Rogers was suspended with pay. According to public salary disclosures, Rogers was paid an annual salary of $123,472 in 2024.

Rogers’ most recent court appearance was earlier this month, and he is expected to enter a plea in a Cobourg courthouse in June.

Anonymous intimate partner violence case

Less than a week after Rogers’ arrest came the news that another Peterborough Police officer had been arrested in connection with an intimate partner violence incident. The officer was subsequently charged with mischief under $5,000.

Details about this case and the officer involved are scarce, due to the nature of the offence. In intimate partner violence cases in Ontario, the names of both the accuser and accused are generally not disclosed publicly, unless there’s a concern for public safety.

We do know that Chief Betts indicated at the time that “this matter is in no way related to the officer’s duties” and that they were temporarily reassigned to administrative duties. The criminal charge of “mischief” refers to interfering with another person’s private property, most often indicating property damage.

Currents asked a Peterborough Police spokesperson about the status of this case and were told it “was resolved in a court in a different jurisdiction in 2024. At the conclusion of that outcome, the officer was addressed in accordance with the provisions of the CSPA [Community Safety and Policing Act], which forms part of their personnel record.”

Ethan Mamers

Peterborough kicked off 2026 with the investigation and subsequent arrest of Peterborough Police officer Ethan Mamers, charged with careless discharge of a firearm.

This follows an incident that occurred on New Year’s Eve when Mamers, who was off-duty at the time, allegedly discharged a legally owned firearm within his home. The police media release indicates that Mamers came to the Peterborough police station in the early evening to self-report the incident, and shortly after that, they received a 911 call from a neighbouring family who just returned home after a dinner reservation to find a bullet hole in their bedroom closet.

Mamers has been transferred to administrative duty and is scheduled to appear again in court on May 5.

The Mamers and Rogers cases are both still before the courts. When Peterborough Currents asked the police about them, a spokesperson referred back to the public statements that were released at the time of the incidents, saying that “nothing further can be addressed” until the matters are resolved by the courts.
