On May 27, the CRTC approved the sale of CISN by Robert McCord to Shaw Cablesystems Ltd. CISN Holdings Ltd., through its ownership of 84.2% of the voting shares, was the controlling shareholder of CISN Radio Ltd. and was controlled indirectly by Mr. Robert McCord. McCord, who will continue as President of CISN Radio Ltd., stated that in order for the station to reach even greater potential, major steps and expenditures were required. As an independent operator, he said his resources for continued growth and expansion were limited. Through the Shaw organization, CISN could reach that higher plateau in its service to the Edmonton community and to the Canadian broadcasting system.

Shaw, the purchaser, was an Edmonton-based company with extensive cable television holdings across Canada, including a cable undertaking serving part of Edmonton. There was no clear cut control of this publicly-traded company. However, members of the Shaw family residing in Edmonton and Woodridge, Ontario owned 59.5% of the issued and outstanding voting shares, and James Shaw of Edmonton was the company's President. Shaw's broadcasting activities focused exclusively on cable television until 1987 when it acquired a number of Alberta radio stations.
