This was the second time a UFC on Fox event was held outside the United States (the first one was UFC on Fox: Gustafsson vs. Johnson, in Sweden, in January 2015) and the first time in Canada.

The event was headlined by a welterweight contest between former WEC Welterweight Champion and former interim UFC Welterweight Champion Carlos Condit and former UFC Middleweight Championship challenger Demian Maia. The bout was scheduled to take place at UFC 202, but was moved a week later to headline this event.

The Ultimate Fighter: China featherweight winner Ning Guangyou was expected to face Marlon Vera at UFC 202. However, due to an out-of-competition failed test and following investigation concluding Ning ingested the substance without fault or negligence, the bout was moved to this event. In turn, the bout was postponed again due to alleged visa issues for Ning, which restricted the timing of his travel.

Josh Emmett was expected to face promotional newcomer Jeremy Kennedy at the event. However, Emmett pulled out of the fight on August 19 with an undisclosed injury. He was replaced by fellow promotional newcomer Alessandro Ricci.
