The mandate of The Sheila Hugh Mackay Foundation is to promote excellence in the visual arts of New Brunswick.

The Sheila Hugh Mackay Foundation is a private foundation created in 1987 to promote the creation of, knowledge of, participation in, appreciation for, and accessibility to New Brunswick's visual arts and fine crafts.

Although Sheila passed away in September 2004, the work of her foundation continues to this day and new initiatives are being planned.
