A gunman opened fire in central Toronto on Sunday night, killing one and injuring 13 people - including a child - before being shot dead, according to police.
Toronto Police said they had responded to a call at around 10pm (9am in Thailand on Monday) in the city's Greektown district.
The police department later confirmed that there were 14 victims, including a female adult who had been shot dead and a young girl who was in critical condition.
The police said the 14 victims did not include the shooter, who was also dead.
Global News quoted a Toronto police source as saying the suspect is believed to have opened fire at police before being shot and killed.
Witnesses described hearing about 20 shots and the sound of a weapon being reloaded several times.
Ontario Premier Doug Ford tweeted out a message of condolence and solidarity, saying: "My heart goes out to the victims and loved ones of the horrific act of gun violence in Toronto. Thank you to all the first responders for acting quickly to help everyone affected."
The incident comes amid growing concerns in Canada's largest metropolis over a spate of shootings - more than 200 - this year. About two dozen have been fatal.
Canada traditionally has relatively low levels of gun violence, particularly compared with its neighbour the United States.
