Earlier today (11-12-14), The CW released the first images of the new Black Canary from 'Arrow'. The photos show Laurel Lance (Katie Cassidy) as the DC Comics character - complete with mask and badass costume.
It looks like we'll see Cassidy assume the role of Black Canary this season, probably in Episode 10 (January 2015).
Instead of posting the photos here, I'll direct you to variety.com, which also has some background on the Black Canary TV history.
