Bell didn't want those stations. They wanted the CITY-TV network. They purchased CHUM which included the CITY-TV network and the A-network. Rogers was then going to buy the A-network which included CKVP-DT. The CRTC said that Bell could not own both CTV and CITY-TV due to rules against ownership of two stations in the same market. As a result, Rogers got CITY-TV network and Bell got the A-Network. Bell has been whining and pouting about it ever since. Bell's idea was probably to own two stations in every major city so it could dominate OTA and the broadcasting of US TV shows in Canada. When they couldn't do that, they started threatening to shut down all the A-network stations in order to get concessions from the CRTC. CHCJ-DT was later launched in order to provide better coverage of the GTA, by CTV2 (formerly the A-Network) since that is a critical market.
Then Bell got the idea that they were going to shut down all their OTA stations and apply to the CRTC to keep simsubs for the two OTA networks they own. The CRTC killed that idea as well. Bell has embarked on a campaign of acquiring as many broadcasting interests as the CRTC will allow. That includes launching CraveTV and using it in an attempt to expand their BDU market share. The CRTC put a stop to that as well. Don't know what Bell is planning next but, if past actions are any indication, it's not likely to be in the best interests of Canadian consumers or well liked by the CRTC.
