Hockey fans paid tribute to the victims of a van attack in Toronto that killed 10 and injured 15 yesterday (April 23).

The video, shot on April 23, shows thousands of people singing along to the Canadian anthem inside a stadium, during the playoff game between Toronto Maple Leafs and Boston Bruins.

The filmer writes: "It was especially emotional given what happened in the city.''

The same two teams played against each other five years ago in a playoff game, few days after the Boston Marathon bombing (April 15, 2013).
