1974–1987: Breakthrough with SCTV
O'Hara started her comedy career in 1974 as a cast member of The Second City (SC) in her hometown, Toronto. Her brother Marcus was also a performer with the company. She originally worked as an understudy and in the Sunday night cast of alternates which performed when the main company had the night off. She was an understudy for Gilda Radner until Radner left for Saturday Night Live. She then joined the touring company of Second City, and had her big break replacing an ailing Rosemary Radcliffe in the lead female part when this touring group was in Chicago. By 1976 O'Hara was SC's resident leading female comic.
In 1976 SC created the sketch comedy show Second City Television (SCTV), for which O'Hara became a regular performer. In the late 1970s, she provided voice-overs for a number of cartoons, work which would continue throughout her career. During a short period in the early 1980s when SCTV was in between network deals, she was hired to replace Ann Risley as Saturday Night Live was being retooled in 1981. However, she quit the show without appearing on air, choosing to go back to SCTV when the show signed on with NBC. She was long rumoured to have left SNL due to conflicts with volatile writer Michael O'Donoghue, but O'Hara denied these claims and said she had left the show due to her dislike for living in New York City.
O'Hara expanded her career on television in the mid-1970s. She appeared in a small sketch role as a maid in a 1975 Wayne and Shuster special on CBC. She appeared in the 1976 television film The Rimshots, the children's television series Coming Up Rosie for a season (1976–77), and television specials, such as Witch's Night Out and Intergalactic Thanksgiving. Her performances on SCTV, which began airing locally in Southern Ontario in the fall of 1976, earned her fame in Canada. The show gradually built up a national and then an international following in syndication. O'Hara left SCTV for a time, missing the 1980–81 season, but returned to the show in time for its pickup by the NBC television network in the US, when it became known as SCTV Network 90. O'Hara's work as a writer on the show earned her an Emmy Award for outstanding writing and three Emmy Award nominations. She left SCTV again prior to its fifth season in 1982, but did return for occasional guest appearances through the show's end in 1984. O'Hara appeared in a number of television series and television films and continued to work in television for the rest of her life.
During the 1990s, she made guest appearances on Tales from the Crypt, Oh Baby, Morton & Hayes, and The Larry Sanders Show. She acted in and directed episodes of Dream On and The Outer Limits, the revival of the 1960s series of the same name. O'Hara guest-starred on top-rated television series including Six Feet Under and Curb Your Enthusiasm. In May 2008, it was announced that she had signed on to star in the upcoming ABC dramedy Good Behavior. Her role in the 2010 television film Temple Grandin earned her three award nominations: a Primetime Emmy Award, a Satellite Award, and a Screen Actors Guild Award.
O'Hara had a successful career in film. She made her feature debut in the 1980 film Double Negative, which also starred her SCTV co-stars John Candy, Eugene Levy, and Joe Flaherty.

She received roles in four of Christopher Guest's mockumentary films, three of which earned her awards and nominations: Waiting for Guffman (1996), Best in Show (2000), A Mighty Wind (2003), and For Your Consideration (2006). Her role in 1999's The Life Before This won her a Genie Award for Best Performance by an Actress in a Supporting Role.
