The sentencing hearing of Nathaniel Veltman begins Thursday.
The now 23-year-old was found guilty of four counts of first-degree murder and one count of attempted murder in November.
Veltman drove his truck into five members of the Afzaal family on June 6, 2021. The family was stopped at a crosswalk on Hyde Park and South Carriage Roads while on an evening walk when the attack occurred.
Talat Afzaal, 74, her son Salman Afzaal, 46, his wife Madiha Salman, 44, and their 15-year-old daughter Yumnah Afzaal were all killed. Salman and Madiha's son, who was nine at the time, was seriously injured but ultimately survived.
Veltman's trial lasted almost 11 weeks in total, with jurors sitting through nine and a half weeks of evidence.
He will face a mandatory life sentence with no chance of parole for 25 years due to the guilty verdict.
During the sentencing hearing, Justice Renee Pomerance will weigh the evidence brought to trial as well as almost 70 victim impact statements to decide whether Veltman's actions should be designated as an act of terrorism.
If he is found guilty of terrorism, it won't affect the length of his sentence, but it will determine his classification in prison and impact his chance for parole after 25 years.
