Selma Alincy, a family friend of Davis's mother, said the bullets came so fast that "everyone who heard it thought it was fireworks."
Peel Regional Police Chief Chris McCord described families running from a "hail of bullets," with more than 100 shell casings recovered at the scene.
Five others were injured, and Davis, who police say was an innocent bystander, was killed steps away from his home.
"He went inside to change his shoes, and he did not even make it back to his apartment," Alincy said.
Police have so far not made any arrests or recovered any weapons. No suspect descriptions have been released.
Alincy spoke with CBC's Metro Morning on Monday about what she saw and heard on Saturday evening, beginning with a panicked phone call from Davis's mother.
"She was just hysterical on the phone," said Alincy. "She kept on saying his name."
Unsure what was happening, Alincy raced to the scene from her home a few minutes away, arriving to see police tape and officers.
"So I ran through the front toward the back of the building, and when I got there, I saw Jonathan laying on the ground… a few doors from where he lives," she said.
"I said. 'No, he's not, they're working on him,"' she said. "When I saw them take the cloth and put it over his body, that's when I knew that he had passed."
Alincy was holding Davis's father. When his mother arrived, she collapsed in her arms as well.
Alincy described Davis as quiet and intelligent — an honour roll student who loved video games and helped his father navigate the world as he lost his vision.
McCord said Sunday that the intended targets of the shooting were preparing to film a rap video at the time of the shooting, but Alincy said Davis was not involved at all.
\”When people dont have hope they can fall on the wrong path,\” Singh said after an event in Sherbrooke. \”And we want to make sure we have all the programs in place — affordable housing, good health care, opportunities for work so that young people can find a positive way forward and not end up in a vicious cycle of violence.\”
In the neighbourhood where Davis lived, grief over his death is coupled with fear of more violence.
"I have a young son, and I'm telling him, after school come straight home," said Alincy. "I'm afraid."
In the building's lobby, a makeshift memorial has sprung up, with flowers, cards and food and water.
Marjorie Judham, an elderly woman who lives in the same complex, said Sunday that she didn't feel up to going to church.
Students at the school Davis attended are being offered additional supports as they grapple with the death of one of their own.
Members of the Peel District School Board's Critical Incident Response Team will be at Lincoln M. Alexander Secondary School today to support staff and students.
Pastor Delroy Sherman, a local community leader, told Metro Morning he hasn't been sleeping since.
"Over the last number of years, I've been burying youths in this age bracket, and it's very sad," he told Metro Morning.
"There are solutions to this gun violence… if the government would listen to us," Sherman said, citing a summer basketball competition that was started in the community to keep young people busy.
Mississauga Mayor Bonnie Crombie said the incident was "a call for us to let us know that we can and should do more."
Federal party leaders, on the campaign trail in Ontario over the weekend, all commented as well, each suggesting different root causes for what's become an increasingly severe problem in the GTA.
The federal government has earmarked $54 million for Ontario over three years to combat illegal gun and gang activity, with the funds earmarked for specialized prosecutors, policing projects and intelligence−gathering efforts in jails.

Police are searching for at least seven suspects who they say descended on an apartment complex west of Toronto on Saturday evening, firing indiscriminately and killing a teen described as an innocent bystander.
A 13-year-old Syrian refugee was among those shot outside an apartment building in Mississauga on Saturday evening. She was the youngest victim, who recently moved to Canada from Turkey with her family, a family friend told CityNews. The young girl was on the first floor of the building when she heard gunshots and ran to the window, where she was hit by a bullet in the Mississauga shooting that left one dead and five injured.
Police say that gunshots erupted on the set of a rap video that was being filmed in the neighbourhood.17-year-old Jonathan Davis was the innocent bystander who was killed in the attack. He was a Grade 12 student at Lincoln M. Alexander Secondary School. Jonathan was pronounced dead at the scene.

The shooting happened at Darcel Avenue near Morning Star Drive just before 6:30 p.m. Peel Regional Police Chief Chris McCord says it was an “ambush-type” attack, reports Durham Radio News. The suspects were dressed in dark clothing and ski masks. McCord says they discreetly approached on foot from the side of a building. Once in position, they indiscriminately fired into the parkette area with semi-automatic handguns and then fled on foot.

Police say that over 100 shell casings were found on the scene of the crime. The Peel District School Board has put supports in place today for students who need it. A 16-year-old boy, two 17-year-old boys and a 50-year-old were also shot, along with Jonathan Davis and the 13-year-old girl. They were taken to hospital and all are in stable condition.
Police say that there are still unidentified witnesses who were standing at an ice cream truck at the time, and they need to come forward. Police have spoken to a few of the witnesses, but not all, and one of those who should come forward is the driver of the ice cream truck.
This brazen act of violence will not be tolerated, said Peel police Chief Chris McCord to 680 News. This incident appears to be a targeted attack and Id like to reassure the community that their safety is the number one concern for me and for the men and women of Peel Regional Police.
Officers say at least seven suspects were involved in the shooting and some fired more than 100 rounds during the incident.
