Henry studied art in Montreal at the École des beaux-arts, ultimately spending most of his life in the Montreal subregion.[2]
Henry is known for his landscape oil paintings and abstract works,[3] and has exhibited in galleries throughout Canada and North America. His work has been characterized as displaying "a serious lack of seriousness", which is also a feature of the artistic movement, "anecdotism", which Henry founded.[4][5][2] Henry’s art features in several prestigious institutional collections, such as at the Royal Bank of Canada, IBM Canada and DuPont.[3]
Henry’s artistic career includes the rehabilitation of a historic house in Saint-Lambert, Quebec, transforming it into the Musée Marsil [fr], and creating "Les femmeuses", an annual exhibition that showcased the work of female artists.[2]
In addition to his artistic endeavours, Henry worked as vice president of communications with Pratt & Whitney, and with Concordia University as president of the consulting committee for the Faculty of Fine Arts.[2]
In 1992, Henry became the president of the Centres les impatients, an organization that uses art therapy to help those suffering from various mental health conditions.[6][2]
