Northumberland OPP officer, Constable James Orser pleaded guilty Monday to Discreditable Conduct at a Police Services Act hearing in Orillia.
The charge stems from a compromising cellphone video Orser made in 2011 of a person and then shared with other OPP officers.
Sentencing submissions will be made May 2 and May 4.
Recently, Constable Orser was docked 80 hours hours pay after writing inappropriate comments on a ticket in 2008.
The OPP is moving to have Orser, who is suspended from duty, with pay, dismissed from the organization.
