You are warmly invited to join the Thornhill Historical Society on Sunday, September 21st from 11am-2pm at the J.E.H. MacDonald House at 121 Centre Street, Thornhill,  for the official unveiling of the Moments of Algoma Group of Seven in Thornhill easel and Group of Seven Commemorative Plaques.

This special event is co-hosted by the Thornhill Historical Society, City of Vaughan and Toronto and Region Conservation Authority (TRCA) Sustainable Neighbourhood Action Program (SNAP) and Moments of Algoma.

Following the ceremony, guests are welcome to participate in guided walking tours through the village of Thornhill, visiting the former homes of five Group of Seven members. The day will also feature a en Plein Air art show, family art event and community booths.

The new easel installation commemorates the Group of Seven’s artistic and cultural legacy and their connection to Thornhill. As part of the broader Moments of Algoma Group of Seven Touring Route, this interpretive panel places Thornhill on the map as a significant stop in the story of Canada’s artistic identity.

The Group of Seven Commemorative Plaques, installed in honour of the Thornhill Historical Society’s 50th anniversary in 2024, mark the homes once occupied by the five members of the Group of Seven who called Thornhill home.

This project is the result of vision, dedication, and collaboration—led by the Thornhill Historical Society and supported by the City of Vaughan, TRCA’s Sustainable Neighbourhood Action Program (SNAP), Moments of Algoma, and our generous donor and benefactor, Lorna Rogers. Her contribution has brought this project to life, celebrating the power of community, the importance of art, and the value of preserving local history.

We sincerely hope you will join us for this meaningful celebration.
