For the employees of OC Transpo and the families of four men, this was a day of remembrance.
It was on April 6, 1999 that one of their former co-workers, who was by then delusional and paranoid, came back to work with a hunting rifle.
David Lemay was a husband and father, who loved to sing.
Brian Guay was a man devoted to his family and friends.
Clare Davidson was his daughter's best friend.
Harry Shoenmakers, was also a husband and father. He didn't have an enemy in the world.
Their killer was Pierre Lebrun, a former stockroom clerk who said he was constantly ridiculed by his co-workers. He committed suicide.
Amazing Grace played as OC Transpo employees, managers and friends watched family members of the victims lay wreaths on the ground. There was one for each of the four men who were murdered.
David Halloran read the prayer.
"One year later we find it difficult to understand life can make such a difficult turn."
Overcome with emotion, he had difficulty making it through the reading.
Stacey Lemay, daughter of David Lemay, was grateful that OC Transpo held the ceremony.
"I think it's important because it's a chance for people who don't know how to come to you to show you they're thinking about you," said Lemay.
But Regional councillor Richard Cantin felt there should have been one more wreath.
"There are four victims of the gunman, and the shooter, and you can't help but feel bad for his family," Cantin said.
OC Transpo officials say many employees are having a hard time turning the page.
Richard White was Pierre Lebrun's last supervisor. He says, "I don't know if we will ever understand what happened. Time heals, people have always told me that. I hope to hell it does."
