↑There are various common abbreviations to distinguish the Canadian dollar from others: while the ISOcurrency codeCAD (a three-character code without monetary symbols) is common, no single system is universally accepted. C$ is recommended by the Canadian government (and The Canadian Style guide) and is used by the International Monetary Fund, while Editing Canadian English indicates Can$ and CDN$; both guides note the।SO scheme/code. The abbreviation CA$ is also used such as in some software packages.
