The attack happened so fast. A white van jumped the curb and ploughed into pedestrians on a street on Yonge Street (the city’s longest street) in North York, north of downtown Toronto. Traffic was light, and people were out enjoying the sunshine. The driver was allegedly 25yo Alek Minnassian, from the Toronto suburb of Richmond Hill. He’s listed on his LinkedIn page as studying at a local college. His motive remains unclear. What will security agencies be doing now?
