RLBC operates a domestic rugby league football competition in British Columbia, Canada that currently features six teams with the addition of the Whistler Wolves for the 2020 season.

The RLBC competition started in May 2012 with 5 teams, Bayside Sharks, Burnaby Lake Rugby Club, Kelowna Crows, Sea to Sky Eagles and Surrey Beavers.

In 2019, the Point Grey Thunder qualified for their first Grand Final after a semi-final win over the Valley Warriors by a score of 34–14.

In 2020, the league expanded to include the Whistler Wolves and added two clubs, the Vancouver Dragons and Valley Warriors, established women's teams to compete.

Currently the RLBC is a self-funded entity and relies heavily on the contributions made by players and sponsors to help pay for the cost of league operations and representative teams.

Players from the RLBC also make up the Western Canada Wild, a regional representative squad for the provinces of Manitoba, Alberta and British Columbia for both men and women.

The "thunderdome" being an event similar to the popular State of Origin series in Australia in which the teams are composed of the best players representing regions.
