"Spiritual Machines" has been noted as being the end of an era for Our Lady Peace, as it was the last album produced by the band's longtime producer Arnold Lanni, the last to feature original guitarist Mike Turner in full, and the last studio album to feature art model Saul Fox on its cover. It was also the last album to feature Maida's high-falsetto singing voice prominently. The album peaked at number five in Canada, where it is certified double platinum.
