Canadian police have shot dead a man in southern Ontario after receiving "credible information" of a plan to carry out a suicide bombing in a public area, local news organisations reported.

CBC News said on Thursday that Aaron Driver, 23, was killed by police at a house in Strathroy, a town about 225km west of Toronto, after he detonated a device that injured himself and another person.

CBC said that Driver had another device that he was about to detonate, before police shot him.

"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," the Royal Canadian Mounted Police said in a statement.

CTV News, citing an internal government memo, said the suspect was planning to use an improvised device to carry out a suicide bombing in a public area. His alleged plan, according to the document, was to kill many people

Intelligence sources, who declined to be identified as they did not have permission to speak to media, told the Reuters news agency that Driver was arrested last year for openly supporting the Islamic State in Iraq and Levant on social media.
