'This is really something that has hit our Oshawa community,' said the school's principal Michael O'Brien.

Fifty-year-old Chris Traynor and his children, 20-year-old Bradley Traynor, 15-year-old Adelaide Traynor and 11-year-old Joseph Traynor were killed in their home during an early morning shooting on September 4.

“I don’t think our community has ever faced anything like this in the history of our great city,” said Oshawa Mayor Dan Carter.
