At Toronto FC home matches, the group is primarily based in sections 111 and 112 of BMO Field which has been named "The Bunker", though RPB members can be found scattered all throughout the stadium.

The mandate of the Red Patch Boys (RPBs) is to support and promote Toronto FC and the sport of soccer throughout Canada, and to help contribute to the atmosphere at all TFC home games.

Along with the other supporter groups in Toronto, they have gained widespread notoriety for showering opposing players with streamers during corner kicks and goal celebrations.

In addition to activities in their home stadium, several members also take part in away games at other MLS venues; notably Columbus, Chicago, and Foxborough.

The group's name is a homage to the Red Patch Devils, a nickname given by Axis forces for the 1st Canadian Infantry Division which fought across Europe during the Second World War.
