Born in Victoria, British Columbia, on 3 January 1985, she had been singing and dancing in amateur stage shows since the age of 4 and couldn't resist the performance bug. After getting an agent, Leah quickly won parts in shows such as Psych, Second Sight and Tin Man, before playing Penelope in Odysseus: Voyage To The Underworld.
Her first feature film lead came in the 2009 horror thriller The Devil's Ground, opposite Daryl Hannah. She followed it up by playing Silhouette's Girlfriend in Watchmen, as well as landing roles in the likes of The Twilight Saga: Eclipse and Rise Of The Planet Of The Apes. Leah has continued to work in a string of television shows such as Caprica, Supernatural, Kill For Me, Arctic Air and The True Heroines. She also occasionally turns up as a cabaret singer in nightclubs for a little fun between roles. Cute Canuck Ms. Gibson has thankfully not shied away from baring all for her art.
