Nathaniel Veltman, 22, is accused of intentionally targeting the family because of their faith, running them over in 2021.
He has been charged with four counts of first-degree murder and one count of attempted murder.
His murder charges include terrorism counts, which means prosecutors must prove his actions were premeditated and deliberate but also motivated by a political, religious, or ideological cause.

Salman Afzaal, 46, and his wife Madiha Salman, 44; their daughter Yumna Afzaal, 15; and Mr Afzaal’s mother Talat Afzaal, 74, were killed while on an evening walk on 6 June 2021. The couple’s nine-year-old son was seriously hurt but survived.
Madiha and Salman had come to Canada from Pakistan for a better future, a relation told the BBC.
Mr. Veltman was arrested shortly after the attack in a parking lot close to London’s oldest mosque, where the Afzaal family were devoted members.
The suspect was wearing what appeared to be body armor and a helmet, police said.
The attack sent waves of grief and fear across Canada, as London’s tight-knit Muslim community mourned the loss of a beloved family.
“Tomorrow, September 6th, 2023, marks exactly 27 months since a horrific tragedy struck the Muslim community in London,” he said.
“Our hope is that we can continue to heal as a community and we’ll achieve some level of closure at the conclusion of this trial.”
The Superior Court trial is expected to last about three months.
