Erica Durance was born June 21, 1978, in Calgary, Alberta, Canada and raised in Three Hills, Alberta.
After graduating from high school, Durance moved to Vancouver, British Columbia, to pursue her interest in acting professionally. "I wanted to get my feet wet in a smaller area than Los Angeles when I gave it a try", Durance has said. She continued to study acting, starting out with background work, graduating to commercials, and then guest-starring roles, landing more substantial roles each time.
In 2004, she guest-starred on The Chris Isaak Show playing Ashley, a woman on a date with Chris. In Tru Calling, her character was a contender in a beauty pageant opposite Eliza Dushku's character. On the Sci-Fi Channel, she played an intergalactic librarian in Andromeda and a love interest for Teal'c in Stargate SG-1. She also played a sister to one of the leads in the Canadian show The Collector.
Durance is perhaps best known for her role as Lois Lane on the WB (now the CW) series Smallville. She was a frequent guest star for the fourth season of the show (2004-05) and joined the regular cast for the fifth season (2005-06), sixth season (2006-07), and seventh season (2007-08).
Durance appeared on The Howard Stern Show in September 2004 after she had already filmed a number of her first episodes on Smallville. She has also starred in several films credited as Erica Parker, including the 2003 horror film, House of the Dead.
She was listed as the highest new entrant and cover girl in FHM's May 2006 issue, including the World's 100 Sexiest Women at #38 and was listed by FHM at #20 in the World's 100 Sexiest Women in 2007. She was also the October 2007 cover girl for Maxim.
On October 9, 2006, she again appeared on The Howard Stern Show to promote the DVD release of The Butterfly Effect 2.
On January 3, 2007, Durance was interviewed by Layla El on WWE.com in the third edition of the website's Superstar to Superstar segment. She continues to promote Smallville and the CW. In 2008, Erica will star in Ecstasy based on the #1 bestselling book by Irvine Welsh as Heather.
Parker was the surname of her first husband, which she had taken when they wed in 1996; they separated in 1999 and divorced. Durance married for the second time on January 8, 2005, to Canadian actor David Palffy. They reside in Vancouver.
