Born in Rochford, Essex, England, Tapping moved with her family to Ontario, Canada, when she was one year old.

She also formed a comedy troupe, the "Random Acts", with collaborators Katherine Jackson and Anne Marie Kerr, in Toronto in the early 1990s.

[4] In season 5, however, Tapping's role on the show was reduced to that of "special guest-star" with only occasional appearances[5] because she chose to focus her attention on the development of a new series for Syfy called Sanctuary.

[8] Tapping's directing debut was during the seventh season of Stargate SG-1 on an episode titled "Resurrection", written by co-star Michael Shanks.

[13] Tapping has openly shared the difficult experiences she has undergone through eight miscarriages during her marriage in hope that her story would help other miscarrying women feel less isolated.

A third brother Steven, who suffered from epilepsy and often uncontrollable seizures, died in December 2006 of causes unreleased by the Tapping family.
