JOHNSTOWN, Ont. -- An Ontario provincial police officer has been charged in a collision southeast of Smiths Falls, Ont., that injured a man this summer.

The province's police watchdog says it has reasonable grounds to believe that OPP Const. Timothy Jackson committed a criminal offence in the June 10 crash.

The Special Investigations Unit says a police cruiser and a civilian vehicle collided in the community of Johnstown.

Jackson is charged with dangerous driving causing bodily harm.

He is due in court on Jan. 6.

The SIU says it will not comment further as the case is before the courts.
