Classified by the RCMP as a terrorist act under the Criminal Code , it was the most serious security breach at Parliament Hill since the 1966 parliament bombing . It took place two days after a man used his car to run over two soldiers in Saint-Jean-sur-Richelieu , Quebec , killing one . The two incidents , which attracted international attention , raised concerns about the effectiveness of police actions to prevent terrorist attacks , the prevention of radicalization and the security measures in place at federal and provincial legislatures . The Canadian government had already prepared a bill to expand the courtroom anonymity and surveillance powers of the Canadian Security Intelligence Service ( CSIS ) , Canada 's intelligence agency , which was due to be introduced the day of the shootings , and was postponed by the event . The government introduced new anti-terrorism measures with the '' Anti-terrorism Act , 2015 '' . Security at Parliament Hill is to be stepped up . On June 3 , 2015 it was reported that " RCMP officers have started openly carrying submachine guns on Parliament Hill as part of a visible increase to ... security . " On October 20 , in the 2014 Saint-Jean-sur-Richelieu ramming attack , Martin Couture-Rouleau attacked two Canadian Armed Forces soldiers . Rouleau was a 25-year-old Québécois who became a Muslim convert in 2013 and was a supporter of the Islamic State of Iraq and the Levant ( ISIL ) . Rouleau used his car to run over the two soldiers before being fatally shot by police after an ensuing car chase . Warrant Officer Patrice Vincent , age 53 , subsequently died from injuries
