They may be our biggest rivals on the ice, but when it comes to honouring our American neighbours, Canadians don't pass up on the opportunity to chime in.

The video above, filmed Nov. 18, shows the opening of the Toronto Maple Leafs vs. the Nashville Predators hockey game. When Canadian singer Michelle Madeira began the American national anthem, her microphone failed. So what did the Canadian crowd do? They picked up right where she left off.

(It must be noted, of course, that the Predators have more Canadians than Americans on their team, but the sentiment remains the same.)

It's a heartwarming cross-border exchange that's been occurring more and more recently, most notably following the Parliament Hill shooting, when the Pittsburgh Penguins (who were playing against fellow American team Philadelphia Flyers) opted to play the Canadian national anthem in tribute.

So sure, you know what happened — but don't you want to hear it for yourself? Check out the video above.
