CBC first broadcast the Canadian adaptation Dragons' Den.
The Canadian series is the country’s version of the international business-pitch format associated with Dragon's Den. Entrepreneurs present companies to Canadian investors, explain their numbers and negotiate over ownership in much the same way as contestants in the British programme.
CBC, the Canadian Broadcasting Corporation, launched the series in 2006. The programme became one of the network’s recognisable factual-entertainment properties and developed its own panel, presenter and production identity rather than simply rebroadcasting the BBC version.
This distinction matters because several Canadian networks have carried business or reality programming, and international viewers may know the US series Shark Tank more readily. The question asks about the original Canadian broadcaster, not a later streaming service, repeat outlet or a network associated with another national adaptation.
