COTB charged with criminal negligence causing death and wilfully attempting to obstruct justice; city manager declines further comment while proceedings continue

THUNDER BAY – The Corporation of the City of Thunder Bay has been criminally charged with criminal negligence causing death and wilfully attempting to obstruct the course of justice following the investigation into the death of an 86-year-old Pioneer Ridge resident.

If convicted, the municipality could face a substantial fine and court orders requiring changes to its practices, compliance reporting and public disclosure. For an organization convicted of an indictable offence, the Criminal Code places no statutory ceiling on the fine a judge may impose.

City Manager JC Collin confirmed that charges have been laid but said the municipality would not discuss the case further while it remains before the courts.

“Yes, there are criminal charges that have been laid but since this matter is before the courts, we will offer no further comment until the situation is resolved,” Collin said.

Earlier police announcement named Pioneer Ridge

Thunder Bay Police Service’s March 16, 2026, release announced charges against Marina Gilbert, then 52, and Pioneer Ridge Long-Term Care Home.

Police said investigators began their work on February 11, 2025, following a report about a January 30 incident. They alleged an 86-year-old resident sustained injuries while in a staff member’s care, that additional unreported injuries were later confirmed and that officers could find no documentation of the injuries.

The resident died on March 6, 2025. Police alleged the death resulted from those injuries.

Gilbert was charged with criminal negligence causing death. The release named Pioneer Ridge as facing criminal negligence causing death and obstructing justice charges. These allegations have not been proven in court.

No updated TBPS media release announcing the charges against the Corporation of the City of Thunder Bay was located during research for this report.

Has Thunder Bay faced charges like this before?

A review of publicly accessible news reports and indexed legal records did not identify an earlier prosecution of the municipal corporation for criminal negligence causing death or obstructing justice.

That finding does not establish that the current case is the first in Thunder Bay’s history. Older proceedings may not appear in searchable online records, and a definitive claim would require further archival and court-record verification.

The municipality has faced other prosecutions. A published account of Ontario enforcement cases records an August 16, 2011, conviction under the Ontario Water Resources Act. The city was fined $10,000 for failing to provide a copy of a water-taking permit to a person authorized to take water. That was a provincial regulatory offence, distinct from the Criminal Code charges now facing the municipality.

Charges against individual public officials also do not establish a criminal history for the municipal corporation. The legal identity of the accused matters.

What must the Crown prove?

Criminal negligence involves conduct—or a failure to perform a legal duty—that shows wanton or reckless disregard for another person’s life or safety. The charge of criminal negligence causing death also requires proof that the criminal negligence caused a death.

For an organization, section 22.1 sets additional requirements connecting the conduct of its representatives with a marked departure from the expected standard of care by the responsible senior officer, or senior officers collectively. An employee’s wrongdoing does not automatically establish the organization’s criminal guilt.

The obstruction charge concerns an intentional attempt to obstruct, pervert or defeat the course of justice. It requires proof of deliberate conduct, rather than an administrative mistake alone.

The Crown must prove the charges beyond a reasonable doubt.

What penalties could the city face?

A municipal corporation cannot serve a prison sentence. Section 735 of the Criminal Code provides financial penalties for organizations in place of imprisonment.

These are statutory limits, not predictions of the sentence. The prosecution route on the obstruction charge matters.

For comparison, an individual convicted of criminal negligence causing death faces a maximum sentence of life imprisonment. Obstructing justice carries a maximum of 10 years’ imprisonment when prosecuted by indictment. Those imprisonment provisions do not mean a mayor, councillor or manager would be jailed because the city was convicted. Personal criminal liability would have to be established separately.

A sentence could require changes and public reporting

A fine is only part of the possible outcome.

Under section 732.1(3.1), a court can impose organizational probation conditions requiring the city to:

• Establish policies and procedures to prevent further offences.
• Communicate those requirements to its representatives.
• Identify a senior officer responsible for compliance.
• Report to the court on implementation.
• Make restitution for loss or damage resulting from the offence.
• Publicize the conviction, sentence and measures taken to prevent another offence.

These conditions are available to the court; they are not automatic consequences of a conviction.

When determining the sentence, a judge must consider factors including previous similar offences or regulatory sanctions, steps taken to prevent a repeat, restitution, the costs of investigation and prosecution, and the sentence’s effect on the organization’s economic viability and employees.

What would it mean for taxpayers?

A fine against the corporation would be an obligation of the municipality. Its effect on taxes, reserves or municipal services would depend on the amount, payment terms and the city’s budget decisions.

There is no basis at this stage to calculate a household cost or predict a tax increase. A conviction would not, by itself, establish personal financial liability for councillors or municipal employees.

Collin says accountability will follow proceedings

Responding to questions about accountability, Collin said the city’s limited comment was intended to protect the legal process.

“As for your suggestions about accountability, this has nothing to do with accountability. It has to do with protecting the legal process and those involved in it,” he said.

“We will be transparent and accountable once the legal proceedings have terminated.”

Collin also noted that police issued a media release when charges were first laid. The March release named the staff member and Pioneer Ridge; it did not expressly name the Corporation of the City of Thunder Bay.

The charges against the municipality remain allegations. The city and all other accused parties are presumed innocent unless and until proven guilty.
