At a packed arena in Canada, where NHL hockey teams were set to battle on the ice, the Toronto Maple Leafs were hosting an American team from Nashville.

During the opening ceremony, the singer's microphone failed during the US national anthem and the music suddenly stopped.

The Canadians, in a heartwarming moment, began singing the words, and cheered as they finished up the song.

"I'm sharing this story because I want Americans to know that Canadians love them," writes JKC, who submitted the video to the Good News Network.

"Americans are like our older brother: sometimes we poke fun, and we don't always have the same interests, but we would stand up for them in a heartbeat, and want their lives to be great."
