During the same year, she also had her first starring role as Kelli Presley in Black Christmas (2006). In 2007, Cassidy gained attention for her role as Ruby on the supernatural-horror television series Supernatural, during its third season. She later had a supporting role in Taken.

Cassidy had her breakthrough in 2012, after being cast as Laurel Lance / Black Canary, one of the main protagonists on the television series Arrow, which spawned an entire franchise known as the Arrowverse. Cassidy reprises her role in The Flash, Legends of Tomorrow and voiced the character in the animated web series Vixen. Following her character's death, Cassidy began playing Black Siren, an antagonistic version of her character from a parallel universe, starting in The Flash and continuing on to Arrow.
