CNSX (Canadian National Stock Exchange) is an alternative stock exchange in Canada. It is the first full stock market to be approved by the Ontario Securities Commission in the past 70 years. The CNSX offers simplified reporting requirements and reduced barriers to listing. It is an alternative for micro cap and emerging companies. It had been known as CNQ until the organization re-branded itself in November, 2008. It is fully automated, rather than using the traditional "open outcry" physical trading floor system.
The CNSX is located in Toronto, Canada and maintains a branch office in Vancouver.
In September 2007 CNSX started operating a service called Pure Trading, an electronic communication network where most of the stocks listed on the Toronto Stock Exchange can be traded.
