Council was wrapping up an investigation into allegations of misconduct by the city's auditor general against the city manager when police say several people began causing "repeated disturbances."
Durham regional police say Mayor John Henry asked two people to quiet down but they refused and became argumentative.
Police allege that two men assaulted a security officer while being removed from council chambers and that two plainclothes police officers helped to remove the men and placed them under arrest.
Durham police say the two plainclothes officers were on duty and were at the meeting "proactively" because problems had been anticipated. Police say the security guard and both suspects received minor injuries.
Daniel Hammond, 52, and William Steele, 46, are charged with failing to leave premises when directed and assault, and both were released from custody with conditions.
Steele alleged in an email to The Canadian Press that he was left with multiple injuries after being beaten by "hidden armed officers" who were "planted" in the audience.
A police spokesman said since the case is now before the courts it wouldn't be appropriate to discuss it beyond the statement police released Wednesday.
"We've laid these charges, they're now before the court and we wouldn't be discussing the specific details of it," said spokesman David Selby.
Council voted 8-3 to accept the findings of an investigator who found no wrongdoing in a multimillion-dollar land deal involving the city. It also adopted his seven recommendations, one of which was to eliminate the auditor general position.
