One year after his son was shot and killed by a Toronto police officer on a downtown streetcar, Sammy Yatim's father says questions surrounding his son's death continue to haunt him.

In a statement released Saturday, Nabil Yatim said the police response was "mishandled" and "excessive." He said his son “did not deserve to die” in that manner.

Sammy Yatim was wielding a knife on an empty streetcar on the evening of July 26, 2013 when  Toronto police Const. James Forcillo fired nine shots, striking him eight times. The 18-year-old later died in hospital.

In his statement, Nabil Yatim asked: "Why was he shot so many times? Why was he tasered as he lay dying on the floor of that streetcar? These questions continue to haunt me.

"No parent should have to live through what I have endured. My family and his friends still suffer. I miss him every minute of the day. I will do everything in my power to help create change in how the police respond to these situations."

Yatim’s family has previously said that Sammy was suffering an "an acute emotional disturbance" at the time of the shooting.

His death, which was captured on video that was posted online, sparked outrage and prompted Toronto Police Chief Bill Blair to request a report taking a broad look at how officers interact with people in crisis.

Among the 84 recommendations made in the 'lethal force' report, released Thursday, was a call for an increased use of Tasers, the use of police psychologists in recruiting and training, and the establishment of a police and mental health oversight body. 

The report also called for an increased use of body cameras for police to record such incidents.

After an investigation by Ontario's Special Investigations Unit, Forcillo was charged with second-degree murder in Sammy Yatim’s death.

Forcillo is expected to go on trial next year.
