At least seven wounded after nightclub shooting in Toronto

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.

Toronto police Chief Mark Saunders said that the incident is "very bothersome," but given the number of witnesses, the crime is "very solvable."

During a news conference following a violent Simcoe Day weekend in the city, Saunders said that from Saturday to Monday, police were called to 11 separate firearm incidents.

Shortly before 5 p.m. ET on Monday, police responded to a 12th gun-related incident in the Lawrence Heights area just south of Yorkdale shopping mall. One man was taken to hospital with gunshot injuries, which Toronto police and paramedics say were serious but non-life-threatening. A second victim made it to hospital on their own, police said.

On Monday, Mayor John Tory released a statement calling the recent rash of gun violence "absolutely unacceptable."

"I know Toronto police are working non-stop to find those responsible for these shootings and to bring them to justice," Tory said. "I urge anyone with information that could help investigators solve these shootings to call police or Crime Stoppers."

Tory also repeated his calls for a handgun ban. City council debated a handgun ban in June, despite the fact different levels of government have to be involved.

The Toronto incident comes after two mass shootings in the US states of Ohio and Texas over the weekend claimed the lives of 31 people in total.
