All of the most recent victims were male and one of them was in critical condition with a bullet wound to the head, CP24 TV said.
The others sustained non-life-threatening injuries, the Toronto Star said.
While Friday's Colorado mass shooting at a movie complex that killed 12 people and injured 58 others dominated Canadian headlines, Toronto politicians and police grappled with the rash of gun violence in the city.
Self-described conservative Mayor Rob Ford was scheduled to meet Monday with Ontario's Liberal premier, Dalton McGuinty, with demands for more funding for anti-gang and drug police officers.
Ford is also seeking a meeting with Conservative Prime Minister Stephen Harper to appeal for a federal ban on handguns and changes to immigration law to expel people convicted of gun offenses.
In past days, the issue has seen both liberal and conservative groups calling for a combination of better social and educational programs in poor and immigrant neighborhoods as well as stepped-up law enforcement.
Police Chief Bill Blair told CITY TV Thursday night police couldn't "arrest away" the problem.
