CTV Nature Channel is a Canadian discretionary specialty channel owned by CTV Specialty Television, a joint venture between Bell Media and ESPN Inc., with minority interests owned by Warner Bros. Discovery via licensee Discovery Science Canada Company. It broadcasts factual and reality-style series related to science, nature, and history.
The network was originally launched on August 15, 2001 as Discovery Civilization Channel, a digital cable spin-off from Discovery Channel based on the U.S. network of the same name (now Investigation Discovery), focusing on programming related to history and international culture. On September 27, 2010, the channel relaunched as Discovery Science, becoming a Canadian version of Science Channel.
On January 1, 2025, the channel relaunched as CTV Nature Channel, due to Bell losing the rights to Warner Bros. Discovery factual and lifestyle brands to Rogers Sports & Media (who will primarily distribute Science Channel programming through its streaming and on-demand platforms, foregoing a new specialty channel).
