The Air Canada Foundation and beloved hockey star and humanitarian PK Subban joined forces to inspire Canada to come together in song - creating the world's largest Christmas Carol to bring cheer to sick kids spending the holidays in the hospital.

On December 15th, 2015 PK Subban and The Air Canada Foundation hosted a magical Christmas surprise party for kids who would be spending Christmas at the Montreal Children’s Hospital. During this party PK and the children sang jingle bells together while PK filmed the song on his iPhone. He asked Canadians to join in and upload their versions of Jingle Bells using #CanadaCarols to social media.

This simple nationwide challenge sparked a phenomenal movement that broke the rules and revealed the inherent goodness inside of us and the power of social media to help fuel connection and positivity.

Canadians of all walks of life joined in – new Canadians from Syria, Our Prime Minister Justin Trudeau, rock stars, Newscasters, Twitter, The Weather Network and the Canadian Embassy in D.C. We strung all of our voices together to create the world's largest Christmas Carol.
