The O-P-P's use-of-force policy is under the microscope as a coroner probes the 2009 shooting death of Levi Schaeffer near a remote First Nation community.
The inquest will also look into the circumstances that led to Schaeffer being shot by officers in the Osnaburgh Lake-area.
O-P-P officers and members of Schaeffer's family are expected to testify at the inquest, which is expected to run through Friday.
