On June 28, 2022, a shootout occurred between two gunmen and responding police officers following a robbery of a Bank of Montreal branch in Saanich, British Columbia, Canada.

Both gunmen, later identified as twin brothers Mathew and Isaac Auchterlonie, were killed by police, while six officers were injured, three of them severely.

She also described the perpetrators as remaining calm throughout the robbery, wearing balaclavas and all-black clothing with armored vests, and being armed with what appeared to be Soviet semi-auto rifles.

The road was later closed off, and nearby homes and businesses were evacuated due to a possible explosive found in a vehicle belonging to the robbers.

[3] Police later confirmed that 4 additional firearms, 3500 rounds of ammunition, and more than 30 improvised explosive devices were located inside the vehicle.

[11] The RCMP's Vancouver Island Integrated Major Crime Unit took over the investigation and treated the incident as an attempted murder.

[10] During a press conference on July 2, RCMP identified the suspects as twin brothers Mathew and Isaac Auchterlonie from Duncan.

Alex Bérubé of the RCMP's Vancouver Island Integrated Major Crime Unit alleged that the intention of the Auchterlonie brothers was "to shoot and kill police officers in what they saw as a stand against government regulations, especially in relation to firearms ownership".

However, the brothers abandoned their initial plan due to fears that an upcoming move out of their house would draw attention to their weapons.
