The girl was 15 when she was arrested in June 2012 as the alleged ringleader of a violent pimping operation.
In September, two other teen girls entered mid-trial guilty pleas for their alleged roles. None can be named under provisions of the Youth Criminal Justice Act.
The alleged ringleader pleaded not guilty to 33 charges, including human trafficking, making child pornography and assault, at the outset of the trial in April 2013.
During the trial, three girls, between 13 and 17 years old at the time, described how they were delivered to johns and forced to hand over earnings for performing sex acts.
Four other girls testified about their experiences. One described being photographed naked in a bathtub when she was too drunk to move.
Justice Diane Lahaie is expected to deliver her decision Wednesday morning. The Crown plans to pursue an adult sentence for the teen, now 17, if she is found guilty.
Mid-trial guilty pleas
The Crown did not pursue adult sentences for the two teen girls who pleaded guilty.
The youngest, who was 15 at the time of her arrest, pleaded guilty to three counts of human trafficking involving three girls, one count of making child pornography, one count of luring and one count of robbery. She was sentenced to the maximum three years in jail. She is now 17.
The oldest, 16 at the time of her arrest, pleaded guilty to one count of each human trafficking, robbery, uttering threats and breaching conditions. Lahaie rejected a joint sentencing submission from the Crown and defence that suggested the teen be released with 12 months of time served and two years of probation. The teen will undergo a psychological assessment before her sentencing. She is now 18.
