The event marked the promotion's seventh visit to Toronto and first since
UFC 231 in December 2018. A
UFC Women's Bantamweight Championship bout for the vacant title between former title challenger
Raquel Pennington and
Mayra Bueno Silva took place at the event. The title was vacated when former champion
Amanda Nunes announced her retirement immediately after defending her title at
UFC 289. A
UFC Featherweight Championship bout between current champion
Alexander Volkanovski and
Ilia Topuria was expected to take place at this event. However, Volkanovski was instead pulled to face
Islam Makhachev for the
UFC Lightweight Championship at
UFC 294. As a result, this fight was pushed back one month to headline
UFC 298. A light heavyweight rematch between former
KSW and
UFC Light Heavyweight Champion Jan Błachowicz and
Aleksandar Rakić was expected to take place at the event. The pairing previously met at
UFC on ESPN: Błachowicz vs. Rakić where Blachowicz won the fight after Rakić was rendered unable to continue due to a knee injury. However, Błachowicz withdrew due to a shoulder injury and the bout was scrapped. A light heavyweight bout between former title challenger
Dominick Reyes and
Carlos Ulberg was scheduled for this event. However, in late December 2023, it was announced that match was off due to an injury sustained by Ulberg. They were rescheduled for
UFC Fight Night: Brady vs. Luque two months later. At the weigh-ins, Ramon Taveras and
Malcolm Gordon missed weight. Taveras weighed in at 139.75 pounds, three and three quarters pounds over the bantamweight non-title fight limit. Gordon weighed in at 127.5 pounds, one and a half pounds over the flyweight non-title fight limit. Both bouts proceeded at catchweight with Taveras forfeiting 30% and Gordon 20% of their purses, which went to their opponents Serhiy Sidey and Jimmy Flick respectively. Prior to the event, UFC president
Dana White announced that the event had set new records for the highest grossing arena gate in UFC history and Canada. During the event's broadcast, former
UFC Lightweight Champion Frankie Edgar was announced as the next "modern wing"
UFC Hall of Fame inductee during June's International Fight Week festivities in Las Vegas. ==Results==
