Calgary Dollars is Calgary’s complementary currency system, started by the Arusha Centre in 1996, that brings together local talents and resources to strengthen our local economy and build community. A community’s true wealth lies in the skills, talents and capabilities of its members. We believe that every person has something of value to offer to their neighbours. By encouraging local production and consumption, we are committed to creating a healthy economy that is rooted in a healthy society and a healthy ecosystem.
