As an educator her work has been devoted to the incorporation of art into all areas of the curriculum. She has coordinated various school-related multi-media projects and has been a guest artist on several occasions at the Labrador Creative Arts Festival.

As a former board member of the Newfoundland & Labrador Arts Council, VANL-CARFAC (Visual Artists Newfoundland & Labrador) and the Art Association of Newfoundland & Labrador, as well as a participant in numerous classes and workshops, Margaret's interest in all aspects of art has been evident. Since 1986 she has participated in over 60 group exhibitions.

In 1990 Margaret initiated the annual Art Exhibition at the Southern Shore Shamrock Festival. The show features the work of over 20 Southern Shore artists. The Exhibition grows in popularity each year.

In 1999 Margaret's daffodil triptych was chosen by the Canadian Cancer Society for use in their fundraising campaign. The proceeds from her poster "Flowers of Hope" continue to aid the "Families Can Beat Cancer" program.

In 2003 her solo exhibition "Sunshine on My Shoulders" featured over 40 watercolour mainly of the flowers of the eastern part of the province. This exhibition was held at Memorial University of Newfoundland Botanical Garden where she paints regularly.

"A Brush With History: The Gardens of the Colony of Avalon" was her most recent solo exhibition. For the months of July and August, 2006, the Colony of Avalon archeological site interpretation centre in Ferryland, south of St. John's, was the venue for an exhibit of 30 watercolour pieces depicting a number of the plants of the 17th century Colony of Avalon gardens. During the month of September, selected pieces from the summer exhibition and new works on this theme were mounted at the Cynthia I. Noel Gallery in St. John's.

September of 2008 saw the results of a collaboration of Margaret and Irish artist Andrea Jameson in an exhibition "From an Island to an Island: Landscapes of the Souteast Shores" at Five Island Gallery in Tors Cove. These paintings captured representations of the southeast shores of Newfoundland and Ireland. Currently Margaret is preparing for a 2010 exhibition in County Waterford, Ireland.
