"Unison" met with mixed reviews.
It was largely influenced by the 1980s soft rock sound that was a fit for the adult contemporary radio format.
The album hit all the right notes with critics.
Jim Farber of Entertainment Weekly wrote that Celine's vocals were "tastefully unadorned" and that she never attempted to "bring off styles that are beyond her."
Stephen Erlewine Thomas of Allmusic declared it as "a fine, sophisticated American debut."
Jan De Knock of Chicago Tribune said that "though Dion's big voice invites comparisons to the power-pop stylings of Taylor Dayne and Laura Branigan... she also has a deft touch with an R&B groove."
The album earned Celine two Juno Awards for the "Album of the Year" and the "Female Vocalist of the Year."
