Julia Benson (born Julia Anderson) grew up in Vancouver, Canada, where she trained as a ballet, tap and jazz dancer. At the age of thirteen, she joined the Vancouver Youth Theater, touring parts of Vancouver's mainland. As a result of this, she was then invited to perform at the Abderdeen Youth Festival, in Scotland.
As she grew older, Benson decided all she wanted to do was act and so enrolled at the University of British Columbia, graduating in 2001 with a degree in theatre and psychology. Upon graduation, she then trained as an actress at David Mamets' Atlantic Theater Company in New York City, before moving into film and television.
Her most recognised role is that of 2nd Lieutenant Venessa James in Stargate Universe, for which she won the 2010 Leo award for "Best Supporting Performance by a Female in a Dramatic Series." Aside from acting, Benson also co-created and co-produced a half hour single-camera comedy pilot for City TV. She married Peter Benson in 2009.
