"Tout près du bonheur" (meaning "so close to happiness") is a duet between Marc Dupré and Celine Dion, released as a music download on 11 April 2006 in Quebec, Canada.

On 22 December 2006, Dion and Dupré performed the latter version also during his concert at the Lionel-Groulx Theater in Sainte-Thérèse, Quebec, and later during Dion's historic performance in front of 250,000 spectators to celebrate Quebec's 400th anniversary, which was included on Céline sur les Plaines DVD.

The music video was supposed to be shot in the Mojave Desert but because of Dion's health conditions it was directed 8 May 2006 at The Colosseum at Caesars Palace, Las Vegas by Ivan Grbovic.

On 23 October 2006, Dion and Dupré won a SOCAN Award as composers of "Tout près du bonheur."

Later Dupré wrote music for "On s'est aimé à cause," a song which appeared on Dion's 2007 album D'elles.
