Canadian military police, and its unit, the Canadian Forces National Investigation Service (CFNIS), have faced increasing criticism of widespread incompetence and bungling of investigations.

In January 2025, a judge stayed assault and sexual assault charges against a Canadian Forces member after determining that military police had tampered with evidence and showed bias in their investigation. Superior Court of Ontario Justice Cynthia Petersen noted in her written decision that the misconduct by the CFNIS "in this case is so egregious and systemic that it shocks the community's conscience."

In June 2025, the MPCC issued a report that painted Canada's military police leadership as shutting down complaints and mismanaging investigations to the point where a criminal convicted of attempted murder almost went free.
