On December 1, 2010, Tri-City became the third Canadian roller derby league to be granted membership in the Women's Flat Track Derby Association, Having only completed two full home seasons, Tri-City gained membership status with WFTDA ahead of their Toronto-based sisters at Toronto Roller Derby.

History and league structure
Tri-City has three house teams, the Vicious Dishes, the Venus Fly Tramps, and the Total Knock Outs, which play each other at home, as well as against other leagues' house teams. Then-league member Motorhead Molly played for Team Canada at the 2011 Roller Derby World Cup.

In December 2013 it was announced that Tri-City would be hosting a Division 2 tournament in 2014, August 22–24 at the Waterloo Memorial Recreation Complex. This was the first time a WFTDA playoff tournament was held outside the United States, and the tournament was won by Ottawa's Rideau Valley Roller Girls.

Originally known as Tri-City Roller Girls, in March 2014 the organization rebranded as Tri-City Roller Derby. Beginning in 2015, Tri-City hosts an annual invitational tournament called "Beaver Fever" at the Waterloo Memorial Recreation Complex.
