The fourth season of MasterChef Canada originally premiered on March 3, 2017 on CTV before concluding on June 1. In the United States, this season started showing on The Cooking Channel on October 10, 2017. In the finale, Trevor Connie was announced as the winner of the season. Connie also guest starred in an episode of season five. This was the first season to forsake the show's traditional audition phase, instead directly facing the twenty-four finalists with a surprise challenge in their hometowns that would be finished in the MasterChef Canada kitchen.
Runner-up Dorothea "Thea" VanHerwaarden, who originally finished second, Mai Nguyen, who originally finished fourth and Barrie McConachie, who originally finished third place all returned to MasterChef Canada: Back to Win. Barrie placed 9th. Mai placed 5th. Thea was runner-up again.
