[3][4][5] In April 2013, Natasha St-Pier stated during a broadcast of the radio programme Faites entrer l'invité (presented by Michel Drucker) that she is a cousin four times removed of Pope Pius X.

In 1992, she was spotted by Alain Morisod and invited to participate in the Sweet People Show, a program for young talents produced by a local television station in Quebec.

In July 1995, she recorded her first single: "Le parcours du cœur", written to celebrate the fifth anniversary of the Maurice Tanguay Foundation for underprivileged children.

In the late 1990s, during a tour in Quebec, she was offered the opportunity to replace Julie Zenatti in the role of Fleur-de-lys for the Canadian French-language production of Notre-Dame de Paris (directed by Luc Plamondon).

[13][8] In 2002, her collaboration with Pascal Obispo on the album De l'amour le mieux propelled Natasha St-Pier to her greatest commercial success.

Her victory, with that of Lynda Lemay as Top Female Artist of the year, received favourable remarks in the Canadian House of Commons from Mark Assad (Liberal, Gatineau) and Robert Lanctôt (Bloc Québécois, Châteauguay) two days later.

[29] She promoted the album with the singles "Tant que c'est toi", "Quand on cherche l' amour", "Je te souhaite" and "Mourir demain" (recorded with Pascal Obispo); the latter sold 182,000 copies in France and was ranked #24 in the European charts.

[31][32] At the beginning of January 2006, St-Pier released a studio album entitled Longueur d'ondes,[33] including the singles "Un ange frappe à ma porte", "Ce silence" and "Tant que j'existerai".

The event, presented by Michel Drucker and Claudy Siar, was broadcast live in prime-time on France 3 under the title Eurovision 2006, et si c'était vous?.

[38] In November 2009, she released her seventh album, Tu Trouveras: 10 Ans De Succès, which is largely a "Best of" compilation of previously recorded songs, but also included the new single "L'instant T".

[42] The same year, Natasha St-Pier opened the 20th Salon du Chocolat at Paris, wearing a dress made of chocolate in the style of a geisha (芸者).

Roberto Ciurleo conceived the idea of setting to music the devotional poetry of Saint Thérèse of Lisieux, and commissioned French musician Grégoire as composer.

Also in 2013, she recorded the song "Aimer" with the male quartet Il Divo; it appeared as a track on the group's album A Musical Affair (French edition), released in November 2013.

Other singers recording tracks on the album with the quartet included Hélène Ségara, Florent Pagny, Anggun, Lisa Angell, Vincent Niclo and Sonia Lacen.

[47][48] On 7 December 2013, St-Pier and Anggun were invited to sing their duet "Vivre d'amour" at the 21st annual Vatican Christmas concert (Concerto di Natale XXI edizione) in Auditorium della Conciliazione, Rome.

[50] In October that year, she also gave a concert in a theatre at Le Puy-en-Velay, presenting a mixture of her greatest hits from 2001-2006, together with songs from the album Thérèse – Vivre d'amour.

Several songs were recorded as duets with singers including Roch Voisine, Michel Fugain, Grégoire, Tony Carreira, Edith Kit Godin and Danny Boudreau.

[57] In 2016, St-Pier recorded the song "Mon pays bleu", originally written by folk singer Roger Whittaker as "Durham Town (The Leavin')".

[51] On 9 August that year, St-Pier gave a concert ("Confidences pour un piano") at Courseulles-sur-Mer in Normandy, as part of a week-long festival of Acadian culture ("La semaine Acadienne").

The new album was titled Thérèse de Lisieux – Aimer c'est tout donner, and featured music and lyrics by Thomas and Benjamin Pouzin of Glorious.

She wrote three of the song texts ("Par amour" and "Peu m’importe"), which were set to music by Vincent Bidal (jazz pianist, composer and producer).

[70] In perusing the writings of Thérèse of Lisieux, Natasha St-Pier discovered that the Carmelite had in turn considered St Joan of Arc (French: Jeanne d'Arc) her model.

[74] In June 2024, St-Pier released a new salsa version of her hit single "Tu trouveras", featuring Agustín Galiana et DJ Youcef.

[75] In the same year, she announced a new tour between November 2025 and January 2026 under the title "Mon histoire d'amour c'est vous", with concerts in France featuring her great hits and giving homage to composers and singers who have inspired her.

[77] Beginning 2001-2004, the French media began referring to Natasha St-Pier as one of the grandes voix québécoises (big Quebecois voices) at the centre of contemporary trends in popular music.

Other singers grouped in this category included Isabelle Boulay, Céline Dion, Lara Fabian, Garou, Daniel Lavoie, Lynda Lemay, Bruno Pelletier and Roch Voisine.

[78] The online music database AllMusic describes St-Pier as "A breathy-voiced chanteuse whose polished and unabashedly romantic pop songs have earned her a sizable international audience.

"[8] St-Pier has recorded duets (and trios) with Pascal Obispo, Florent Pagny, Mickaël Miro, Anggun, Élisa Tovati, Sonia Lacen, Grégory Turpin, Les Stentors, Les Petits Chanteurs à la Croix de Bois, Jean-Michel Di Falco, Roch Voisine, Tony Carreira, Michel Fugain, Grégoire, Florent Mothe, Hélène Segara, Vincent Niclo, Anne Sila and Glorious, among others.

Other singers performing on the evening included Julie Zenatti, Emmanuelle Seigner, Arielle Dombasle, Stanislas, Sylvie Vartan, Sanseverino and Micky Green.
