Despite beginning her acting career at the tender age of ten it is her role as accidentally pregnant teen in Juno that has captured everyone's attention.
And this week she is back on the big screen with Inception, which sees her team up with Christopher Nolan and an all star cast lead by Leonardo DiCaprio.
The young Canadian began her career in her native country in a series of television shows until she was cast in independent picture Mouth to Mouth.
She stars as Sherry who meets a radical street collective called SPARK - Street People Armed with Radical Knowledge while she is living on the streets of Europe.They introduce her to a radical new life in this coming of age story as Sherry realises there is a cost to individuality.
From Mouth to Mouth she went on to be cast in 2005 movie Hard Candy that follows a sexual predator and a fourteen year old girl he tries to ensnare and the confrontation between the two, as the girl had a hidden agenda all along.
The movie won three Sitges Film Festival awards in 2005 including Best Picture and Page received praise for 'one of the most complex, disturbing and haunting performances of the year.
She moved onto a small role as Kitty Pryde in X-men: The Last Stand, her first look at the world of the blockbuster. However it is her role as Juno that has earnt the young actress critical praise.
Juno may seem wise beyond her years, but after sleeping with classmate Bleeker (Michael Cera), the pregnant teen quickly realizes how little she really knows about life
With the help of her best friend Leah (Thirlby), Juno finds her unborn child a "perfect" set of parents: an affluent suburban couple, Mark and Vanessa (Bateman and Garner), longing to adopt.
Now, as adolescent Juno is faced with a series of very adult and tough decisions, flirts with adulthood and ultimately figures out where she belongs.
She will draw on the support of her family and friends in order to discover who she truly is, and discover that one bad choice can have a lifetime of consequences.
The film is already being called 2008's Little Miss Sunshine and has been nominated for a Best Picture Oscar and Best Director for Jason Reitman.
For Ellen bagged a Best Actress Oscar nomination for the role, and that was just one in a long line of nominations including Golden Globe, Critic's Choice Awards and the Independent Spirit Awards.
Since her success with Juno the young actress has worked sparingly as she appeared in Canadian movie The Stone Angel before moving onto Smart People and Drew Barrymore's directorial debut Whip It.
But she is back this week as once again steps into the blockbuster movie with Inception, in the role of Ariadne who finds herself learning about the art of inception from central character Dom Cobb.
Dom Cobb is a skilled thief, the absolute best in the dangerous art of extraction, stealing valuable secrets from deep within the subconscious during the dream state, when the mind is at its most vulnerable.
Cobb's rare ability has made him a coveted player in this treacherous new world of corporate espionage, but it has also made him an international fugitive and cost him everything he has ever loved. Now Cobb is being offered a chance at redemption.
One last job could give him his life back but only if he can accomplish the impossible-inception. Instead of the perfect heist, Cobb and his team of specialists have to pull off the reverse: their task is not to steal an idea but to plant one.
If they succeed, it could be the perfect crime. But no amount of careful planning or expertise can prepare the team for the dangerous enemy that seems to predict their every move. An enemy that only Cobb could have seen coming.
And the young star has plenty of projects on the horizon, having already completed filming on Peacock and Super she is currently filming Tilda with Jason Patric and Diane Keaton.
She has also been linked to freeheld.
Inception is released 16th July.
