HALIFAX — Ontario’s police watchdog says no criminal charges should be laid against two Mounties who mistakenly shot at a bystander outside a Nova Scotia firehall as they were searching for the man responsible for a mass shooting that would claim 22 lives.

In April 2023, Ontario’s Special Investigations Unit (SIU) was mandated to determine if the inquiry that investigated the mass murder had unearthed new information about what happened at the Onslow firehall on April 19, 2020.
