Thousands took to the streets on Friday (June 11) in support of a Canadian Muslim family who were run over and killed last Sunday.
The police have described the attack as a hate crime.
The four victims, who spanned three generations, were killed while out for an evening walk near their home.
A fifth family member, a 9-year-old boy, survived.
People in London, Ontario marched around 5 miles from the spot where the family was struck down to a nearby mosque -
a site close to where suspect Nathaniel Veltman was arrested by police.
Some carried placards that read 'Hate has no home here' and 'Love over hate.'
Similar events were also held in other Ontario cities.
The attack has sparked outrage across Canada.
Politicians from all sides have condemned the crime, spurring growing calls to take action on hate crimes and Islamophobia.
The alleged driver of the truck, 20-year-old Veltman, made a brief court appearance on Thursday and will be back in court on Monday.
He faces four charges of first-degree murder and one of attempted murder.
Canadian Prime Minister Justin Trudeau has called the killings a "terrorist attack", and has vowed to clamp down on far-right groups and online hate.
