At least seven people were injured following a shooting at a nightclub in the Canadian city of Toronto, police said, adding that one of the wounded was in critical condition. Shell casings have also been recovered outside the club.
"It's very concerning", she said of the shooting.
Two people made their own way to hospital with injuries believed to be non-life-threatening.
"We had over 100 people at the club and someone was brazen enough to pull out a gun and start shooting, Saunders said".
"I know Toronto Police are working non-stop to find those responsible for these shootings and to bring them to justice", he said, adding "I urge anyone with information that could help investigators solve these shootings to call police or Crime Stoppers".
No suspect descriptions have been released, but Saunders said that the case should be "solvable" as there were many witnesses.
Saunders said 33% of the shootings this weekend happened in the northwest part of the city. "I've got people that are shot". In 2018, 613 people were shot in Toronto in 428 separate incidents.
Toronto Mayor John Tory also condemned the gun violence on Twitter Monday.
Saunders said the decision to ban guns is up to politicians, but he welcomes anything that removes firearms from Toronto streets.
Not all the shootings resulted in injuries.
Police continue to investigate.
On Sunday morning, police were called to a mansion on The Bridle Path where they found a man on the ground with a gunshot wound to the torso.
Most of the shootings occurred at night, Chief Saunders said, saying that people living a 9-to-5 lifestyle are unlikely to be at risk of gun violence while going about their daily lives.
Saunders said that in four of the 11 shooting occurrences that took place over the weekend, no victims were located.
The shootings occurred over a busy long-weekend in Toronto, which hosted the Toronto Caribbean Carnival.
He cautioned people attending bars or clubs to leave if they felt unsafe and said that the increased number of people celebrating in Toronto over the long weekend may have been a factor in the spike in shootings.
Two of those injured in the gunfire escorted themselves to the hospital before police arrived.
