The Canadian version is produced by Castlewood Productions and began airing on 10 September 2008 on Discovery Channel (Canada) and Discovery HD, hosted by comedian Adam Growe. Filming on the second season was recently completed, with 26 new episodes that premiered in September 2009. It airs in Canada instead of the American version of the series, which airs on the affiliated USDiscovery Channel network.

The Canadian version closely mirrors the structure of its US counterpart, retaining familiar features like “Shout Outs”, “Red Light Challenges”, and the “double or nothing” Video Bonus option at the end of each game. However, the Canadian version differs in its heavier focus on questions of science, technology, nature and adventure, as opposed to purely general knowledge. Regular questions are worth $25, $50, $100; while Red Light Challenge questions are worth $75. In the second season, a third “life line” was added: when contestants reach the $100 questions, they have the option to “swap out” a question, and the Cash Cab dispatcher will give them a new question.

Following the success of the first season, Canada’s host Adam Growe was invited to host a special season premiere episode of the American Cash Cab on December 23, 2008, which promoted the feature film Frost/Nixon.
