The Reckoner is the award-winning student newspaper of Marc Garneau Collegiate Institute. During the school year, The Reckoner publishes every day on its website. Additionally, The Reckoner produces a monthly printed newspaper, which is distributed to the school community.

The organization is comprised entirely of dedicated student volunteers: the best writers, artists, photographers, designers, and developers of the school. In 2012, the organization was named Ontario’s Best High School Electronic Newspaper by the Toronto Star.
