There is a secret place hidden in the Don River Valley, between highways and subways, under bridges and behind trees; Todmorden Mills is a cross-section of Toronto, stacked century-by-century, and layer-by-layer upon itself. From an Indigenous waterway to industrial hub, from a prisoner of war camp to a modern arts and theatre venue; each community has made its mark and added another layer to explore.

The same wealth of natural resources, which brought Indigenous peoples to the Don River Valley, has been a magnet drawing settlers, industrialists, workers, artists and families for centuries.

Together, they have shaped Todmorden Mills into its current role as a vibrant natural, historic and cultural landscape.

Todmorden Mills allows visitors to immerse themselves in Toronto’s history through the daily lives of the working people who made the lumber, flour, beer and bricks that built our city.

Todmorden Mills Heritage Site opened to the public in 1967 as part of East York’s contribution to the celebration of Canada’s centennial. In 1821, the Helliwell family settled in the area and established a brewery and distillery. They re-named the area Todmorden after their home town in Lancashire, England as the landscape of the Don Valley was reminiscent of it. The Todmorden paper mill, now the Papermill Theatre and Gallery, was the first of its kind in Upper Canada to produce machine-made paper. It provided newsprint for some of the colony’s first publications including William Lyon Mackenzie’s newspaper The Colonial Advocate.

The Todmorden Mills Heritage Site grounds are home to a 9.2 hectare Wildflower (Nature) Preserve. The trail winds through several different habitats including Upland Forest on the slopes, Bottomland Forest, Swamp, Pond, Dry Meadow and Wet Meadow. The Wildflower Preserve is a long-term, ongoing project undertaken by volunteers. Their aim is to reintroduce the native plant species that were here when the settlers arrived and to remove the invasive non-native species that have been introduced. The preserve provides a green oasis within a major urban centre and is a highly valued spiritual, cultural, and environmental space.
