On February 20, 2026, a Thunder Bay Police Service sergeant was convicted of breach of trust and obstructing justice in Thunder Bay, Ontario. Justice Michael Block ruled that the officer broke the law and misused his position while performing his duties.

The judge described the actions of Michael Thomas Victor Dimini as militantly illegal police conduct during an arrest in 2020. The court found that the sergeant made a false statement regarding his behavior during that incident.

This conviction is seen as a significant moment for a police force that has faced years of criticism regarding its internal culture and public accountability. Local advocates suggest the verdict shows a move toward ensuring officers are held responsible for their actions in the city.

The case comes as former police chief Sylvie Hauth also faces pending criminal charges for breach of trust and obstruction of justice. These legal proceedings are part of a larger effort to address long-standing issues within the organization.

Current police leadership is working on changes to improve how the service operates and interacts with the community. Many residents see these court outcomes as a necessary step for restoring public trust in local law enforcement.
