The Calgary Roller Derby Association (CRDA) was formed in 2007 when a group of girls created a not-for-profit, skater-owned, skater-operated roller derby league. The league is structured so that every member has the chance to be involved in the organization – both on and off the track. We welcome women of all shapes, sizes, age, abilities, backgrounds, professions and skill levels. All we ask is that you are committed to having a good time, being part of an enthusiastic and dedicated team, and are willing to try something new!
