1987-1992
On August 27th 1987, after many years of successful operation of its various cable systems, Shaw Cablesystems (which was later to become Corus Entertainment) made its first venture into over-the-air broadcast ownership with the acquisition of two Red Deer radio stations, CIZZ-FM and CKGY-FM. Further acquisitions by Shaw during this period included CISN-FM Edmonton (1988), CHAY-FM Barrie (1990), CKCK-FM Woodstock (1991), and CFOX-FM and CKLG-AM Vancouver (1992).

1993-1997
Shaw Cablesystems Ltd changed its name to Shaw Communications Inc., to more properly reflect its diversification into over-the-air broadcasting. Over the next four years, Shaw would acquire several more radio stations, including CHQT-AM Edmonton (1993), CFNY Brampton/Toronto (1994), CKRY-FM Calgary (1996) and CING-FM Burlington (1997).

1997
On September 2nd, former CTV President John Cassaday joined Shaw Communications Inc. as Executive Vice-President of the corporation, as well as President and CEO of Shaw Media. JR. Shaw, Chairman and CEO of Shaw, said that Cassaday's role would be to help the company "...to position Shaw as a true communications company with significant interests in both content and distribution."

1998
On November 6th, the CRTC approved an application by Shaw Communications Inc for permission to transfer all its shares in various broadcasting undertakings, to a new wholly-owned subsidiary titled Mediaco, and subsequently to a holding company, Holdco.

1999
On September 1st, Shaw Communications Inc announced that the company would be separated into two distinct publicly-traded corporations, Shaw Communications Inc. and Corus Entertainment Inc. Shaw Communications Inc. would continue to carry on Shaw's cable television, internet access, telecommunications and satellite business, while Corus, with Cassaday as President, would assume ownership of the Holdco properties and carry on Shaw's radio broadcasting, specialty television, digital music services and cable advertising service business. Corus thus became owners of the eleven radio stations previously purchased by Shaw, and later the same month the company made a deal with Blackburn Radio to buy CFPL-FM and CFPL-AM London, plus CFHK-FM St. Thomas/London.

2000
Effective March 31, Corus acquired the Canadian broadcasting assets of Power Broadcasting Inc. consisting of 17 radio stations and four television stations for $114 million. The broadcasting assets acquired include 11 radio stations in Ontario, including properties in Guelph (CJOY-AM and CIMJ-FM), Kingston (CFFX-FM and CFMK-FM) and Oshawa (CKDO-AM and CKGE-FM), and six radio stations in Quebec between Montreal and Rimouski. The television stations in Ontario (CKWS-TV — Kingston and CHEX-TV in Peterborough and CHEX-TV in Oshawa) and Quebec (CHAU-TV) were affiliates of the CBC and TVA, respectively.

On July 6th, following almost two years of negotiations, Corus received CRTC approval to acquire control of WIC Premium Corporation. This added twelve more radio stations to the Corus line-up, and a number of pay, pay-per-view and other discretionary television services. As a condition of the approval, Corus was required to sell off the 50% interest in The Family Channel that had been held by WIC Premium.

The radio stations involved were CHED-FM and CKNG-FM Edmonton, CKNW-AM and CFMI-FM Vancouver, CHQR-AM and CKIK-FM Calgary, CJOB-AM and CJKR-FM Winnipeg, CHML-AM and CJXY-FM Hamilton, and CFYI-AM and CILQ-FM Toronto.

The specialty services Corus acquired included Western Canada pay television services SuperChannel Ltd and MovieMax Ltd, and WIC-VC Ltd.'s pay-per-view service, plus a 40% ownership position in the Teletoon English and French specialty services.

On November 14th, in a move that would further diversify Corus's activities, the company completed the acquisition of Nelvana Ltd, a Canadian producer and distributor of children's programming and products. On November 24th, Corus was awarded licences for a number of new category 2 (discretionary) specialty channels, including Edge TV, RAI Canada, Parent TV, Pet TV. The Classical Channel and The Jazz Channel. Not all of them would get launched.

On June 28th, the Association of Canadian Advertisers (ACA) announced that their Gold Medal Award for 2004 would go to Corus President and CEO John Cassaday.

On August 10th, the CRTC gave its consent to Corus selling their two stations in Red Deer, Alberta, CIZZ-FM and CKGY-FM, to Newcap Inc. (Newfoundland Capital Corporation Ltd).

2006
With the closing down of CKTS-AM Sherbrooke, the number of radio stations operated by Corus was reduced to 50.

2007

2008
On August 22nd, Corus received CRTC approval to acquire effective control of a numbered company, 1708484 Ontario Inc., whose shares had previously been held by CTVglobemedia. With the purchase, Corus acquired ownership of specialty channel Canadian Learning Television (CLT). On November 3rd, the channel was relaunched as VIVA, a speciality channel offering "....programming targeted to Canadian women in the dynamic boomer demographic".

On September 1st, Corus reduced its radio station ownerships to 52 with the sale of CHRC-AM radio to a Quebec City corporation that owned the Hockey Club Les Remparts de Québec.

On September 18th, the CRTC approved two more specialty channel applications from Corus. These were for (a) YTV POW! which would "...offer programming from international markets featuring the latest trends in non-violent action, adventure, superheroes, comedy adventure and interactivity..", and (b) YTV OneWorld "....that would offer programming from around the world targeting children aged 6 to 17 and their families. The schedule would include programs devoted to entertainment, humour, travel, games and science and technology."

2009
On January 8th 2009, the CRTC announced a public hearing to be held in Gatineau, Quebec on March 31st. Corus Entertainment was listed as one of eleven applicants for a new FM radio licence to serve Ottawa, Ontario and Gatineau, Quebec. Corus’s application, and those of eight of the other ten applicants, had been denied on August 26th 2008, but an Order in Council had required the Commission to reconsider its decision.

2010
On January 29th, Corus announced that they were closing two Montreal radio stations, CINF-AM and CINW-AM, as of 7pm that evening. "After years of effort," said Corus Quebec Vice-President Mario Cecchini, "it is clear these AM stations are not viable." The decision left Corus with one of only three AM stations in Montreal, CKAC Sports. While some staffers were relocated to other Corus radio properties, ten employees lost their jobs.

2011
On July 27th, the CRTC announced the renewal of the broadcasting licences for the various television services affiliated with the Corus Entertainment Inc. broadcasting ownership group from 1 September 2011 to 31 August 2016.

In announcing this decision, the Commission said that it was implementing its new group-based licensing policy for large private English-language ownership groups. This policy was developed to prepare both the broadcasting industry and the Commission for the new reality of large, integrated broadcasting ownership groups. Under this policy, the Commission would reduce its focus on Canadian exhibition and concentrate to a greater extent on ensuring stable funding to Canadian production through programming expenditure requirements, particularly in regard to programming that continued to be under-represented in the Canadian broadcasting system. In addition, the Commission said it had also introduced a much greater level of flexibility in the manner in which television services would make and account for Canadian programming expenditures.

On November 9th, the CRTC announced a hearing in Calgary on February 7th 2012, at which it would hear an application by Corus Entertainment Inc., on behalf of its wholly owned subsidiary CKIK-FM Limited, to amend the broadcasting licence for the AM radio programming undertaking CHQR Calgary.

The licensee proposed to add an FM transmitter in Calgary to broadcast the programming of CHQR, "in order to adequately serve the population of Calgary".

The transmitter would operate on frequency 106.9 MHz (channel 295A) with an effective radiated power of 1,000 watts (non-directional antenna with an effective height of antenna above average terrain of 243.6 metres).

The applicant stated that the proposed FM transmitter would provide a reliable high-quality signal on the FM band to listeners in downtown Calgary who were no longer able to obtain satisfactory reception of CHQR on the AM band.
