Trudeau honours Federicton shooting victims as he opens Toronto street festival

Prime Minister Justin Trudeau honoured the victims of the fatal Fredericton shooting during a visit to Toronto's Greektown _ the scene of an other rampage last month _ to help open a popular street festival.

Trudeau told the crowd to send love and support to those reeling in Fredericton after two police officers -- Const. Robb Costello and Const. Sara Burns -- and two unidentified civilians were killed earlier Friday.

The annual "Taste of the Danforth'' celebrates the Toronto area's many restaurants and diverse food and drink offerings.

The Danforth Avenue area was where a man began spraying bullets last month, killing a teenager and a 10-year-old girl.

It remains unclear what motivated the shooting, but the suspect's parents have said their son suffered from severe mental illness.

The opening of the festival also included a minute of silence and acknowledged the efforts of first responders, including the many people who rushed to help the victims.
