VANCOUVER, British Columbia — A 30-year-old man was charged with multiple counts of murder on allegations he killed 11 people when he rammed a crowd of people at a Filipino heritage festival in Vancouver, as hundreds attended vigils across the city for the victims and the Canadian prime minister visited the site on the eve of a federal election.

Vancouver residents gathered at a makeshift memorial on Monday to honor victims of a car ramming attack that killed 11 people and injured dozens more.
