Abdishakur Abdi-Dahir, 29, travelled from the Toronto area to Ottawa for a wedding celebration on September 2, 2023. Around 10:21 p.m. that night at the Infinity Convention Centre, gunfire erupted outside the venue and police say roughly 50 rounds were fired into a crowd of wedding guests. Authorities found eight people injured; Abdi-Dahir and fellow Toronto resident Said Mohamed Ali were pronounced dead and six others survived with injuries ranging from non-life-threatening to critical.

Police described the attack as targeted at individuals believed to be attending one of the two weddings that night, but they have stated that Abdi-Dahir, Ali and the others struck were not thought to be the intended targets. Investigators characterized the circumstances as connected to street-level activity and said there was no evidence of a hate motive. Multiple witnesses and a large volume of gunfire produced conflicting accounts; detectives collected surveillance, dashcam and doorbell video and asked guests and nearby residents for help.

As of September 2026 the homicide remained unsolved with no arrests or publicly identified suspects. Anyone who attended that wedding or has information about the shooting is asked to come forward.
