Early life

Hennessy was born in Edmonton, Alberta. Her father, John Hennessy, was a meat salesman and sales/marketing executive, a job that required considerable travel and resulted in frequent moves for the family. Her mother, Maxine, a secretary, left the family in 1982, leaving her daughter to be partially raised by her paternal grandmother, Eleanor, in Kitchener, Ontario. She has a younger brother, John Paul "J.P." Hennessy, Jr., and an identical twin sister, Jacqueline, who is a magazine writer and TV show host in Canada. Hennessy has Irish, French, Swedish and Italian ancestry on her father's side, and mostly Ukrainian Gypsy, as well as Austrian, ancestry on her mother's. She attended Stanley Park Senior Public School, then graduated from Grand River Collegiate Institute in Kitchener, Ontario and used to busk in the Toronto subway.

Hennessy and her sister played twin call girls in 1988's Dead Ringers, in which both debuted. She was short listed for the role of Dana Scully on The X-Files according to Gillian Anderson, the actress who eventually got the role.

In 2000, Hennessy wrote, produced, and jointly directed (with Elizabeth Holder) an independent film mockumentary titled The Acting Class, which looked at the trials and tribulations of a dysfunctional acting class. The film co-starred her identical twin sister Jacqueline, and included cameo appearances from a number of Hennessy's former Law & Order co-stars. She also starred in the film Nuremberg, as Elsie Douglas.
