It was a violent Halloween in the Greater Toronto Area this year as a triple stabbing and multiple shootings marred the holiday.

The chaos occurred during widespread power outages throughout the City of Toronto caused by strong winds that dislodged branches and damaged power lines.

At around 11:40 p.m. Thursday, police were called to a "rowdy party" with at least 200 attendees in a fraternity house near the corner of Madison and Lowther avenues in midtown Toronto.

According to police, a fight broke out after a 19-year-old man and 15-year-old girl were denied entry to the house.

In an ensuing brawl, three people were stabbed. All of the stabbing victims were males aged 18, 19 and 25, respectively, according to Toronto police Const. Victor Kwong.

One of the victims remains in life-threatening condition in hospital.

Two other people were also hurt in the confrontation.

Police initially said after the incident that six people had been stabbed, but later revised their information Friday morning.

Kwong said the 19-year-old man and 15-year-old girl who were not allowed into the home have both been charged with the following:

1 count of attempted murder.

3 counts of aggravated assault.

3 counts of assault with a weapon.

1 count of weapons dangerous.

Both of the accused are scheduled to appear in court on Friday, police said.
