One of the soldiers died, as did Couture-Rouleau when he was shot by police upon apprehension after allegedly brandishing a large knife. Police speculated that the incident was deliberate, alleging the driver waited for two hours before hitting the soldiers, one of whom was wearing a uniform. The incident took place in the parking lot of a shopping mall 30 miles southeast of Montreal, "a few kilometres from the Collège militaire royal de Saint-Jean, the military academy operated by the Department of National Defence."

The right-wing Canadian government wasted no time in seizing on the incident to promote its fear-mongering agenda over terrorism, which includes pending legislation to vest its intelligence agency, CSIS, with more spying and secrecy powers in the name of fighting ISIS. A government spokesperson asserted "clear indications" that the driver "had become radicalized."
