UPDATE 4.30am: A 10-YEAR-OLD girl and 18-year-old woman have been confirmed dead and 13 others are injured after a gunman went on a deadly rampage along a busy Toronto street.
The killer mowed people down with a handgun outside a restaurant in the Canadian city's Greektown at around 10pm on Sunday local time.
He died after an exchange of gunfire with police.
Witness Andrew Matzios said he had just said goodbye to some friends when he saw a man in a dark baseball cap begin firing at people waiting to cross the road, before turning and shooting into a gyros store.
"He has this look in his face full of hate - he was trying to kill people - like a dog baring his teeth," Mr Matzios told the Edmonton Journal.
A woman then ran past the shooter and stumbled, added the witness. The gunman stopped firing, turned and shot her two or three times as she lay on the ground.
"He went back and finished her off," said Mr Matzios, who described it as an execution.
"The woman who died on the scene, she was shot in front of my eyes."
The shooter then returned to the corner, still shooting.
"Obviously he wanted to do the most damage, kill as many people as he could," said Mr Matzios.
Toronto Police chief Mark Saunders said the injured ranged in age from 10 to 59, and were being treated in hospital.
At least five of those shot were in a serious or critical, but stable, condition. St Michael's Hospital trauma surgeon Dr Najma Ahmed said three of those people needed immediate life-saving surgery.
Mr Saunders refused to release the suspect's name. He said authorities "do not know why this has happened yet" but did not rule out terrorism.
UPDATE 1am: POLICE say a second victim has died after a gunman opened fire on a busy Toronto restaurant strip, injuring 13 people including a child who is in a critical condition.
Three people are dead including the gunman after the shooting in the city's Greektown neighbourhood, a spokeswoman for the province's Special Investigations Unit, Monica Hudon, said.
Police Chief Mark Saunders said the attack was not random and he did not rule out terrorism as a motive.
He said a nine-year-old girl was in a critical condition.
Just hours after he pulled out his gun, eyewitnesses shared video footage of the moment the lone man pulled the trigger.
The footage was shot from a second storey balcony shows a man, dressed from head to toe in black, walking quickly down the Danforth Avenue footpath. He then pulls a pistol as he turned towards a shop front.
Witnesses say he continued firing as he moved on, with victims seen scattered across a wide area. The scene was described as a "crazy" scene of "carnage".

Toronto Police chief Mark Saunders said a "man with a handgun" shot 14 people, killing a "young lady" and leaving a little girl aged "eight or nine" in a critical condition.
The other victims are being treated in hospital but their conditions were not immediately clear.
Mr Saunders confirmed that a fifteenth person, the gunman, was killed after an "exchange of gunfire" with authorities.
Witnesses have shared video footage online of the moment the lone gunman, dressed completely in black, opened fire on the busy strip which is popular with locals and tourists for its many restaurants, cafes and shops.
