Dr. Fay has performed with the Vancouver Symphony Orchestra, Kitchener-Waterloo Symphony, Windsor Symphony Orchestra, London Symphonia, Niagara Symphony Orchestra, and Opera Ontario. She was a member of the National Academy Orchestra of Canada for two seasons and her reed trio Trio Pistachio was one of a select number of chamber groups invited to perform in the live round of the 2011 Fischoff National Chamber Music Competition. Her composition Canine Miniatures (2006) for oboe and bassoon was chosen for performance at the 2012 International Double Reed Society Conference in Oxford, Ohio, where she performed it with oboist Roger Roe of the Indianapolis Symphony.

​Dr. Fay holds a Doctor of Music in Bassoon Performance from Indiana University. She has also holds a Master of Arts in Music Theory from the University of British Columbia, a Master of Music in Bassoon Performance from Ithaca College, a Diploma in Chamber Music from Wilfrid Laurier University, and a Bachelor of Music from the University of Toronto. Her most influential bassoon teachers include William Ludwig, Julia Lockhart,  Lee Goodhew, Nadina Jackson, and Chris Palmer.

In her spare time, Dr. Fay enjoys running through the piney woods of Nacogdoches, walking her Brittany spaniel, board games, playing with her son, and working on her no longer top-secret project: tap dancing while playing the bassoon. She was thrilled to have been selected to appear on Season 2 of Canada's Smartest Person in Fall 2015. You can watch her go head-to-head with a surgeon, an engineer, and a football player through the CBC Canada's Smartest Person webpage.

A native of Halifax, Nova Scotia, Dr. Margaret P. Fay joined the faculty at Stephen F. Austin State University in 2020. She teaches Applied Bassoon, Music History, and Woodwind Methods. She has enjoyed finding creative ways to help the SFA Bassoon Studio thrive during the pandemic, taking advantage of the East Texas climate to continue with in-person lessons and weekly studio classes outdoors, and holding outdoor studio recitals that feature SFA's two contrabassoons.

Before joining the faculty at Stephen F. Austin State University, Dr. Fay taught at Western University in London, Ontario, the University of Guelph, and Wilfrid Laurier University. During her three years of doctoral course work at Indiana University, she taught six undergraduate courses as an Associate Instructor of Music Theory. She has conducted master classes at the University of Victoria and Kenyon College. In the summer, she teaches at the Bobcaygeon Music Camp and Tumble Reeds Double Reed Workshop, which she directs with her husband Graham Mackenzie, who is an oboist.
