Claire Guimond has established herself as a leading baroque flautist, first in Canada and more recently on the world scene. She is based in London and Montreal. Claire is a founding member and artistic director of Ensemble Arion, with whom she has frequently toured North and South America and Europe. She performs regularly with Tafelmusik, features in radio and TV broadcasts, and plays at many festivals in Europe and North America, performing under such distinguished conductors as Ton Koopman, Andrew Parrot, Jordi Savall, Nicholas Mcgegan, Philippe Herreweghe and Bruno Weil.

Her recordings with several labels are distributed worldwide and have been praised by the international musical press. Her version of the sonatas by Joseph Bodin de Boismortier, with harpsichordist Luc Beauséjour, earned a 10/10 in the French Magazine Repertoire. The same magazine has rated her solo recording of Telemann's Fantasias as one of the two definitive versions: the other being an interpretation recorded by her former teacher Barthold Kuijken in 1978.

Claire was Artistic Director of the Lamèque International Baroque Music Festival in New Brunswick, Canada from 2000 to 2006.
