The second anniversary of the deadly van attack in Toronto is even more difficult this year due to the COVID-19 pandemic and the recent shooting rampage in Nova Scotia, Toronto Mayor John Tory said Thursday.

The mayor started a day of virtual commemoration for the 10 people killed and 16 injured on April 23, 2018, when a man drove a rented van down a busy sidewalk on Yonge Street in north Toronto.

"We will not be broken," Tory said live on YouTube. "Let us take inspiration, both from those we lost, and from the heroes who responded to the tragedy, as we rise to the challenges of today."

A local community group will host a virtual vigil Thursday night rather than gathering at the site of the attack, and Tory has asked mourners to avoid gathering or placing flowers and other items near the site.

Shortly after his arrest two years ago, Alek Minassian told police he committed the attack for retribution against society after being shunned by women for years.

The judge overseeing the trial, which has been delayed due to the COVID-19 pandemic, said it will turn on Minassian's state of mind — not whether he carried out the attack.

Tory said the city will never forget those who died and were injured that day.

Ten lit candles, representing those who died, will be placed in the mayor's office window to face toward the city hall square, where the flags will be lowered to half-mast and the Toronto sign dimmed to honour the victims.

Ji Hun Kim, So He Chung, Geraldine Brady, Chul Min Kang, Anne Marie Victoria D'Amico, Mary Elizabeth Forsyth, Munir Abdo Habib Najjar, Dorothy Marie Sewell, Andrea Bradden and Beutis Renuka Amarasingha died that day.

"I know that can make it more difficult for some to bear," Tory said. "That will not stop us from remembering all the lives that were lost on April 23, 2018."

He said the city is also mourning the loss of life after a shooting rampage in Nova Scotia left 22 people dead.

"This year is especially difficult for many people as we experience as a nation another senseless act of violence and loss of life in our sister province of Nova Scotia," he said.

"We continue to mourn with the residents Nova Scotia and I want them to know that Toronto is with you during this time and will continue to support you in any way that we can."
