The band formed in 1999 after the dissolution of another band, called Perfectly Normal. In 2005 they released a split EP with Alexisonfire on Dine Alone Records, on which each band covered two of the other's songs, plus an original song.
That same year, director Alex Liu followed the band through the recording process for The Red Tree, filming a documentary entitled The Start to This May Be the End to Another. The documentary was released as part of The Moneen DVD: It All Started with a Red Stripe on May 13, 2008. The dvd has been nominated for a Juno Award for Music DVD of The Year.
Moneen began recording their fourth studio album The World I Want to Leave Behind in December 2008, which was released September 15 2009.
