Founded in 1999 and controlled by the Shaw family, Corus Entertainment is one of the "Big 3" broadcasting companies in Canada (alongside Rogers and Bell Media). In addition to the Global network and their radio station group, Corus owns a portfolio of brands that mainly target women, children, and families: including animation studio Nelvana and publisher Kids Can Press.
Corus was first created as a spin-off of Shaw Communications' media assets. Shaw later acquired Canwest when they went bankrupt in 2010, and operated their assets as Shaw Media. Shaw Media itself was composed of assets that were previously owned by Canwest, as well as firms acquired by Canwest, including assets from Western International Communicationsnote and Alliance Atlantis. On April 1, 2016, Shaw Media was re-organized and merged into Corus Entertainment in exchange for cash and stock to budget Shaw Communications's purchase of the wireless carrier Wind Mobile. To reflect this, Corus adopted a new logo for the first time since its inception in 1999.
Canadian Multichannel Networks owned by Corus include (channels previously owned by Shaw Media, Canwest, WIC or Alliance Atlantis after 1999 are marked with a *):
- ABC Spark*: a Canadian version of what is now known as Freeform.
- BBC Canada*: A joint venture that airs programming from The BBC and other UK imports.
- Dejaview*: A channel that airs "retro" television series.
- DTour*: a lifestyle channel which primarily airs shows sourced from Travel Channel. DTour originally launched as Prime, a general-interest entertainment channel targeting Baby Bloomers. Prime later relaunched as TVtropolis, which focused on iconic television series...originally. TVtropolis was the originator of Wipeout Canada.
- CosmoTV: Based on Cosmopolitan Magazine
- The Global Television Network (Global)*: the flagship broadcast network, initially formed in 1974 but not a major player in the industry until the late 1990s.

In addition to its own output, Teletoon has also co-produced several series with Cartoon Network.

- YTV: A youth network targeting kids and pre-teens. YTV is known for its longtime association with Nickelodeon, having imported and, eventually, co-produced several shows with the network.
Defunct networks include:

- Drive-In Classics: A channel which focused on showing B-movies popular at drive-in theatres in the 1950s to 1970s, as well as some television series of the same genre. On March 1, 2010, it became a Canadian version of Sundance Channel, and it was eventually shut down on March 27, 2018.
- Dusk*: Originally named Scream, a network for horror, thriller, and suspense programming that was owned as a joint venture between Corus and Alliance Atlantis. It later decayed into a more supernatural and suspense-oriented channel after adopting its latter name in September 2009, but Dusk only lasted more than two years before it was shut down and replaced by ABC Spark.

In 2016, Movie Central was shut down, allowing The Movie Network to expand westward.
- Encore Avenue*: Similar to Moviepix (later known as TMN Encore), this service focused on classic movies.
- Teletoon Retro: A spinoff of Teletoon based on the program block of the same name. With the channel's launch in 2007, Teletoon also briefly brought back the block on weeknights before the late-night Detour block.
