Page was born on February 21, 1987, in Halifax, Nova Scotia, to Martha Philpotts, a teacher, and Dennis Page, a graphic designer. He was assigned female at birth and went by his given name, Ellen, prior to transitioning in 2020. Page attended the Halifax Grammar School until grade 10, and spent some time at Queen Elizabeth High School. After graduating from the Shambhala School in 2005, Page spent two years in Toronto, studying in the Interact Program at Vaughan Road Academy, along with close friend and fellow Canadian actor Mark Rendall.

Page first acted on camera in 1997 at the age of ten, starring as Maggie Maclean in the CBC Television movie Pit Pony, which later spun off into a television series of the same name that ran from 1999 to 2000. For the television series role, he was nominated for a Gemini Award and Young Artist Award. In 2002, Page starred as Joanie in the film Marion Bridge, which is noted for being his first feature-film role. In the same year, he was cast in the television series Trailer Park Boys in the recurring role of Treena Lahey, which he played for five episodes.

Page had roles in the films Touch & Go and Love That Boy in the early 2000s, and he also starred in the television films Homeless to Harvard: The Liz Murray Story and Ghost Cat in the same year. For Ghost Cat, he won the Gemini Award for Best Performance in a Children's or Youth Program or Series. In 2004, Page starred in the drama Wilby Wonderful, for which he won an award at the Atlantic Film Festival and was nominated for a Genie Award. Also in 2004, he had a recurring role in season 1 of the series ReGenesis as Lilith Sandström, daughter of the show's protagonist.

In 2005, Page received recognition for his role in the movie Hard Candy, where he portrayed Hayley Stark, a teenage girl who takes a pedophile hostage. The film was a critical and commercial success, and he received acclaim for his performance, with USA Today praising him for his role, stating that Page "manages to be both cruelly callous and likable" and gives "one of the most complex, disturbing and haunting performances of the year". For the role, he won the Austin Film Critics Association Award for Best Actress in 2006, among other awards and nominations. Also in 2005, he starred in the British film Mouth to Mouth. In 2006, Page appeared in X-Men: The Last Stand (2006) as Kitty Pryde, a girl who can walk through walls. In the previous X-Men movies, the part had been used in brief cameos played by other actors, but never as a main character. The film was a commercial success.

In 2007, he had his widespread breakthrough for his leading role as the title character, a pregnant teenager, in the coming-of-age comedy-drama film Juno. A critical and financial success, the film was widely considered to be one of the best of the 2000s, and Page's performance earned critical acclaim. Film critic A. O. Scott of The New York Times described him as "frighteningly talented ... who is able to seem, in the space of a single scene, mature beyond [his] years and disarmingly childlike", and Roger Ebert said that no other actor had a better performance in 2007 than Page, whose "presence and timing are extraordinary". For his performance, Page was nominated for several awards, including an Academy Award for Best Actress, a BAFTA Award for Best Actress in a Leading Role, a Critics' Choice Award for Best Actress, a Golden Globe Award for Best Actress — Motion Picture Comedy or Musical, and a Screen Actors Guild Award for Outstanding Performance by a Female Actor in a Leading Role. He also won a Canadian Comedy Award, an Independent Spirit Award, and a Satellite Award for the role, as well as numerous critics awards, including Detroit Film Critics Society, Austin Film Critics Association and Florida Film Critics Circle. Also in 2007, he appeared in The Stone Angel, and led the films An American Crime and The Tracey Fragments, the latter of which also earned him critical acclaim, with the Boston Herald writing that "It is also a further reminder that Page is the real thing. But we knew that already". He won the Vancouver Film Critics Circle Award for Best Actress in a Canadian Film, among other accolades.
