The Holland Marsh is a flat intensive muck crop farming region in Ontario, Canada consisting of fertile peat moss. It is located in the floodlands of the Holland River, a waterway that flows into Lake Simcoe, located northwest of Toronto, near Bradford-West Gwillbury, Ontario. Based upon provincial soil analysis and current agricultural production, the Holland Marsh area is deemed to contain some of the most fertile soil in the country - organic, heat retentive black material that supports a very wide variety of vegetables, fruits and flowers.

The marsh and river, part of the Lake Simcoe watershed, are named after Major Samual Holland, the first Surveyor General of Upper Canada. Known as Canada’s “salad bowl” or “vegetable basket” it is a community of some 125 farms, farmers and farm families - located just 40km north of Toronto's CN Tower - has for decades been considered a crown jewel of agricultural production.

Before it was converted to farmland the Marsh was a source of food for local first nations. Around 1825 early European settlers began fishing and hunting in the area. In the early 1900s a mattress factory in nearby Bradford, Ontario began harvesting Marsh grasses for mattress filler.

As with most things, time and other factors take their toll. The Holland Marsh is slowly losing nutrients and organic black soil. It is now part of The Greenbelt - a 1.8 million-acre expanse of protected land around the Greater Toronto Area and Golden Horseshoe - ensuring that future generations will be able to enjoy its agricultural beauty.
