Nitrogen Studios

Cinesite Vancouver, formerly known as Nitrogen Studios Canada Inc., commonly and sometimes still referred to as Nitrogen Studios, is a Canadian animation company founded by husband and wife duo Greg Tiernan and Nicole Stinn in October 2003 in Vancouver, British Columbia. The company was best known for animating the British television series Thomas & Friends from the 12th season to the 16th season, before leaving the show, with Arc Productions, now known as Jam Filled Toronto, taking over.

After Thomas & Friends, Nitrogen Studios would later animate the 2016 adult-animated comedy film Sausage Party, with Tiernan serving as co-director with Conrad Vernon. They would also produce the 2019 animated film The Addams Family and its sequel, based on characters of the same name.

On March 7, 2017, it was acquired by British visual effects and feature animation studio Cinesite Studios.
