Being Erica is a Canadian comedy-drama television series that aired on CBC from January 5, 2009, to December 12, 2011. Created by Jana Sinyor, the series was originally announced by the CBC as The Session, but was later retitled Being Erica before debuting in 2009. It is produced by Temple Street Productions and distributed internationally by BBC Worldwide. The show stars Erin Karpluk as Erica Strange, a woman who begins seeing a therapist to deal with regrets in her life, only to discover a therapist (Michael Riley) who has the ability to send her back in time to actually relive these events and even change them.

In Canada, the second season premiered on September 22, 2009. Only 12 episodes were produced for the second season due to budget cuts at the CBC. On May 11, 2010, the CBC announced that Being Erica was renewed for a third season of 13 episodes. Soapnet announced that it was picking up the full third season as well. Season 3 debuted on September 21, 2010, at 9 pm ET, on CBC Television. In the United States, Season 3 began airing on Soapnet starting January 26, 2011.

The show's fourth and final season aired from September to December 2011. Although the show was never officially cancelled by the CBC, Sinyor told TV Guide during the fourth season run that the series had reached a natural conclusion and she had "no plans" to write or produce a fifth season.

Erica Strange is a young woman, smart and well-educated, but an underachiever who has been perennially unlucky in her career and her love life. After accidentally consuming a drink with hazelnut flavouring, to which she is allergic, she wakes up in the hospital and meets Dr. Tom, who claims that he can help her fix everything that is not going well in her life. Although initially reluctant, she soon learns that what he is offering is the ability to go back in time to relive and even change her deepest regrets.

Each time she faces a problem in the present, Dr. Tom sends her back to revisit a related regret. The situation is rarely as simple as it first appears: in nearly every case, the event she was seeking to avoid by acting differently still occurs, and she must instead seek out new information to uncover the event's real meaning, which gives her new insight into how to handle her problem in the present. It quickly becomes apparent the therapy's true purpose is not to let Erica erase her regrets, but to help her improve her future by learning from past mistakes and making different decisions in the present.

Over the course of the series, the sessions also serve to reveal some of the limitations and complications, as well as the metaphysical implications, of the therapy process — such as whether a patient can intervene to change somebody else's destiny besides their own, whether the therapist can intervene on the patient's behalf to change their past without the patient's knowledge, whether a patient is allowed to reveal the future to another person during a session, and whether the therapy was ever really happening or was merely a dream all along. Later seasons introduce a group therapy session, where several patients gather to discuss and share ideas about one patient's time travel sessions.

Because the show involves time travel, very young versions of the characters are played at times by different actors.

Erica Strange (Erin Karpluk) – the protagonist in the series. At the beginning of the series, she is 32, single, Jewish, and well-educated. However, she is an underachiever who has recently been fired from a mindless customer service job because she is overqualified. She has a nut allergy and after accidentally drinking coffee with nut syrup in it, she ends up in hospital where she is approached by someone she initially believes to be connected with the hospital. He introduces himself as "Dr Tom" and says he is a therapist who can help her. Once home again, she is convinced poor choices made in her past have made her life a failure and seeks Dr. Tom's help to undo many of her mistakes. As the series progresses, she gains confidence in herself and her choices, dates and finds love, and gets promoted to junior editor at a publishing house, from which she eventually gets fired in the penultimate episode of the second season. She has a master's degree in English literature. During the third season she and Julianne start their own publishing company 50/50 Press and become good friends in the process. Having written short stories throughout her life, Erica aspires to write fiction as an author. In the season 3 finale, Erica passes Dr. Tom's test at the end of group therapy and becomes a trainee doctor. The penultimate episode of season 3 ends with Erica walking down a street in Toronto looking for somebody to give her business card to so they can become her first patient. In the series finale of season 4, Erica successfully completes her doctor training and becomes an official doctor. Her office is a quote-plastered artist's studio loft with a honeycomb-style bookcase and a tan leather chair behind a large, red desk. Even though she has to bid farewell to Dr. Tom, the now Dr. Erica remains connected to him through his daughter Sarah who becomes her first official patient. In the episode "Adultescence", a 12-year-old Erica Strange is played by teen actor Samantha Weinstein; Rachel Marcus plays a young Erica in the episode "Fa La Erica"; Grace Arianna Kirby plays a childhood Erica in the series finale "Dr. Erica".
