Toronto police officers accused of GPS tracking victim, orchestrating insurance fraud: court docs

new released margaret court documents reveal sir thomas more inside information nearly charges laid against multiple Toronto police officers in a sweeping corruption probe — including allegations that an officer helped place a GPS tracker on a victim’s vehicle so another person could follow her.

That’s on top of accusations that a different officer arranged to have another person’s vehicle stolen so he could then file a false insurance claim.

None of these allegations have been proven in court, but they shine more light on a months-long investigation York Regional Police have dubbed “Project South,” which has rocked Ontario’s justice system.

Seven active Toronto police officers and one retired officer have been charged in connection with the case, which has resulted in numerous charges including conspiracy to commit murder and drug trafficking.

Toronto police officers face corruption, conspiracy charges in organized-crime probe

The GPS tracking allegations are linked to charges against 49-year-old Sgt. Carl Grellette, who is facing charges including conspiracy to obstruct justice and breach of trust by a public officer.

According to the documents, at some point between the end of December 2025 and the end of January of this year, Grellette allegedly provided details from an ongoing police investigation to a civilian named Jennifer Jasey.

Jasey is also facing charges linked to Project South, including harassment, mischief and possession of a restricted firearm.

The documents say that around that same time period, Grellette gave Jasey advice on how to install a tracking device on a victim’s vehicle, then proceeded to aid Jasey’s harassment of the victim “in the repeated following [of] the victim from place to place using a GPS tracker, causing the victim to reasonably fear for their personal safety.”

Grellette is also accused as part of the investigation of supporting illegal cannabis dispensaries by accepting bribes in exchange for protecting against police investigation.   

The court files also list new details about the case against 42-year-old Sgt. Robert Black, who faces charges including conspiracy to obstruct justice and possession for the purpose of trafficking.

The documents state that sometime last December, Black arranged to have a man’s vehicle stolen so the supposed victim would be paid out by his insurance company. That fraud never actually ended up being committed, according to the filings.

The documents go on to say that Black also allegedly possessed both cocaine and Adderall for the purpose of trafficking.

Black, of Vaughan, is also accused of supporting illegal cannabis dispensaries by accepting bribes in exchange for protecting against police investigation.

The documents also reveal more information about the Crown’s case against 29-year-old Const. John Madeley Jr. — who is still with Toronto police — and his father, retired constable John Madeley Sr., 55.

The court filings say that between the beginning of 2024 up until the end of January 2026, the younger Madeley conducted “unlawful queries of police databases” and provided information to people who weren’t police officers.

That’s on top of using Toronto police’s computer systems with “intent to commit an Offence” over that same time period, according to the documents.

Court filings allege Madeley Sr. Also accessed Toronto police systems in the same way as his son over that same time period — though he retired in April 2025.
