The suspect, who had attacked a policeman and rammed a van into pedestrians in the city of Edmonton, was identified as Abdulahi Hasan Sharif, a 30-year old Somalian refugee, The Globe and Mail, one of Canada's largest daily newspapers, reported Sunday.
Sharif was charged with five counts of attempted murder, five counts of criminal flight causing bodily harm, risky driving and one count of possession of a weapon for a unsafe goal.
Police raised the possibility of terrorism charges on Sunday when revealing that Sharif had been investigated two years earlier for espousing extremist views and was found to have an Islamic State flag in his vehicle.
Sharif is scheduled to appear in provincial court for a bail hearing on the sworn charges on Tuesday morning.
