The album has sold over three million copies worldwide.

The Collector's Series, Volume One is a compilation of some of Dion's biggest hits and few rare tracks. The album features "The Power of the Dream" from the opening ceremony of the 1996 Summer Olympics, duets with Barbra Streisand and Andrea Bocelli, and few rarely heard non-English language songs. It also includes singles which were not issued on Dion's previous greatest hits album All the Way… A Decade of Song: "Where Does My Heart Beat Now", "Only One Road", "Falling into You", "Tell Him", and "The Reason".

Tout en amour was released in France also as a limited edition, including twelve colour postcards with previously unreleased photos of Dion. The album was re-released in October 2004 in few European countries, as part of the Best of the Best Gold series. The gold-disc pressing was housed in a die-cut slipcase, exposing the gold disc and featured the same tracks that graced the standard pressing.
