A 24-year-old Canadian man who police said was an Islamic State group sympathizer was killed Wednesday when officers responded to what they say was a “potential terrorist threat.”

Police shot and killed Aaron Driver In the southern Ontario town of Strathroy —a small place with about 21,000 people roughly halfway between Detroit and Toronto — after he detonated a device that wounded himself and one other. Driver was shot, police reportedly told his family, because he had another device he planned to detonate during a suicide mission in a public space, according to CBCNews.

“The RCMP received credible information of a potential terrorist threat," the Royal Canadian Mounted Police said in a statement Wednesday. "A suspect was identified and the proper course of action has been taken to ensure that there is no danger to the public's safety.”

While it isn’t possible to know exactly how many fighters in any given western country have been radicalized to join the ranks of ISIS and carry out attacks, Canada is said to have one of the lowest rates. In a recent study from the International Centre for the Study of Radicalization and Political Violence, Canada was estimated to have two people per million in their population that have been radicalized.

That figure is quite lower than many European countries that have recently been at the center of terrorist plots, especially Belgium, which has an estimated 46 radicalized people per million population. Behind Belgium is Sweden and Denmark, with 32 and 27 per million, respectively. France has 18 radicalized people per million population.

The United States has about one ISIS fighter per million people in its population.

This isn’t the first time that Canadians have been openly identified as ISIS recruits or fighters. Earlier this year, documents showing at least six Canadian ISIS defectors were leaked.
