Their name was also used for OverActive Media's Overwatch 2 team, who are usually known as the Toronto Defiant.

The Ultra began its life as a professional Call of Duty League (CDL) team.

Toronto was announced as one of the first five cities to host a CDL team for its inaugural 2020 season.

As OverActive Media are a member of the Esports World Cup Foundation Club Support Program (funded by Saudi Arabia's Public Investment Fund) via KOI, who they bought in 2024 from Spanish streamer Ibai Llanos,[3][4] the Ultra name would be used at the 2024 Esports World Cup for their Call of Duty team, as well as a new Teamfight Tactics squad.
