O'Hara was born in 1954^[3] and grew up in Toronto, Ontario, the sixth of seven children. She is of Irish descent^[4] and was raised Catholic.^[5]

O'Hara started her comedy career in 1974 as a cast member of The Second City in her hometown, Toronto.^[6] She was an understudy for Gilda Radner until Radner left for Saturday Night Live.^[7][8] Two years later, this theatre troupe created the sketch comedy show SCTV, for which O'Hara became a regular performer.^[7]

In the late 1970s, she provided voice-overs for a number of cartoons, work which would continue throughout her career. During a short time in the early 1980s when SCTV was in between network deals, she was hired to replace Ann Risley when Saturday Night Live was being retooled in 1981. However, she quit the show without ever appearing on air, choosing to go back to SCTV when the show signed on with NBC.^[9][10]

O'Hara began her career on television, apart from SCTV, in the mid-1970s. She first appeared on television in a small sketch role as a maid in a 1975 Wayne and Shuster special on CBC.

But it was her performances on SCTV, which began airing locally in Southern Ontario in the fall of 1976, that earned her fame in Canada. The show gradually built up a national and then 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 two 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.
