The Calgary Dollar is a local currency in Calgary, Alberta, Canada. While functioning as a limited form of currency within Calgary, it is not legal tender nor is it backed by a national government. Instead, the currency serves (according to its proponents) as a tool for community economic development as well as a focus for community building. The Calgary Dollars organization considers its local currency to be implicitly sanctioned by the Canada Revenue Agency (CRA) based on a CRA publication which discusses the taxation of "credit units possessing a notional monetary unit value" used as a medium of exchange by local barter groups.
The currency 
It comes in denominations of 1, 5, 10, 25 and 50 Calgary Dollars.
In print, the currency is commonly abbreviated as "C$".
The currency was founded in 1996 as a project of The Arusha Centre, in Calgary. The project was originally called the "Bow Chinook Barter Community (BCBC)", and the currency was named the "Bow Chinook Hour".
In 2002, the "Bow Chinook Hour" currency was replaced with "Calgary Dollars" (which was also adopted as the new name of the project).
