Ontario Provincial Police have charged Ottawa Police Association president Matt Skof with breach of trust and obstructing justice under the Criminal Code of Canada.

OPP announced the charges Wednesday, but didn't explain why they were laid against Skof, a sworn police officer currently serving his second term as head of the police union.

The Ottawa Police Service has now suspended him with pay, which is provided by the police association.

Skof's arrest comes after Ottawa police requested help from the OPP to investigate the source of an unverified audio recording that outlined allegations against West Carleton–March Coun. Eli El-Chantiry, the former chair of the city's police services board.

The recording, which was posted online in mid-2018, contained unsubstantiated claims about El-Chantiry. ​One of the voices on the recording also appeared to discuss sensitive details of an ongoing police investigation.

People who shared the file on social media commented that one of the voices on the recording sounded like Skof's, an allegation he has denied.

Union responds

Police association representative Mike Lamothe released a brief statement after Skof's arrest.

"This morning the president of the Ottawa Police Association was charged with breach of trust and obstruction of justice under the criminal code of Canada and was released by the OPP. We have no further comment at this time. We respect the judicial process."

Skof is in his third term as president, having been first elected in 2011 and acclaimed to the position twice since.

The OPA has not named a new president, and said it was business as usual.

In a statement to CBC News last summer, El-Chantiry also denied the allegations against him heard on the recording.

"This is a baseless and slanderous accusation which has been incorrectly attributed to an individual and made by an anonymous source," his statement read.

The charges come with a potential penalty of up to 10 years in prison. Skof was released on a promise to appear in court on March 8.
