Ghislain Lefebvre is born in St-Romuald, Lévis, Qc. He attended elementary and secondary school before having access to the École des Beaux-Arts in Quebec where he studied for four years.
It is in this institution that he will discover and perfect the technique of watercolor. This medium will remain for him, the most natural way of expressing himself on paper. For more than fifteen years, he will teach arts at various institutions in the region. Installed in the countryside, in northern Quebec, he is interested more and more in his environment, especially plants.
The Botanical Garden of Montreal at the suggestion of the director, offers him the walls of his new room "Jacques Rousseau" he will have the honor to inaugurate March 29, 1984. The unexpected success of this exhibition will encourage him to give up his teaching career to devote himself to painting full-time.. He will add to his repertoire, butterflies, birds and mushrooms. Some still lifes and landscapes, incorporating old Quebec houses, do complete all of his achievements.
At the request of Parks Canada, he performs a series of wild plant illustrations for identification purposes on nature trails.
