In 1995, two years prior to Stargate SG-1's premiere, Higginson starred in the movie Jungleground with three other actors from the Stargate franchise: Peter Williams (Apophis), JR Bourne (Martouf), and Lexa Doig (Dr. Lam). Higginson took over the role of Elizabeth Weir from Jessica Steen in a guest spot on the season eight opener of Stargate SG-1. She was then carried over as the leader of the Atlantis expedition on Stargate Atlantis and continued playing that role until the end of the show's third season,[2] afterwards being reduced from a main cast member to a recurring role in the fourth season. She did not reprise the role for the show's fifth season.
In 2015, Higginson was cast in the CBC Television drama series This Life as Natalie Lawson, a lifestyle columnist and single mother who is diagnosed with terminal cancer. The series ran for two seasons,[3] and was ultimately cancelled on January 24, 2017.[4] In 2016, she portrayed Dr. Kessler on the KindaTVweb seriesInhuman Condition.[5]
In February 2021, it was announced that Higginson, who had a recurring role on the CTV medical series Transplant, was upgraded to a regular cast member for season 2 after the rights for the show were acquired by NBC.[6]
