On 22 June 2007, CHUM Limited merged with CTVglobemedia and was renamed CTV Limited. (Regulatory approval of this merger was made conditional on the sale of CHUM's five Citytv stations to Rogers Communications.)
CTV Specialty Television Inc. is jointly owned by Bell Media and ESPN, with 70% owned by Bell Media and 30% owned by ESPN (itself 80% owned by The Walt Disney Company and 20% owned by Hearst Corporation).
Any percentages below refer to the portion of each channel owned by CTV Specialty, with the balance in each case being owned by additional partners such as Discovery Communications.
CHUM Radio was the wholly-owned radio broadcasting division of CTVglobemedia (and remains a division of Bell Media). Through CHUM Radio, CTVglobemedia also owned CHUM Radio Sales.
CHUM Radio owned and operated these following stations:
Dome Productions (35% through CTV Specialty Television Inc, which owns 50% total) — production facilities
Exploration Production Inc. and Exploration Distribution Inc. (56.06% owned by CTVglobemedia) — Discovery Channel Canada's in-house production and distribution companies
