Rouge National Urban Park is unique because it protects not only nature and cultural heritage, but also agriculture. Southern Ontario has some of the most fertile farmland in Canada, but is also home to a large portion of Canada's population. Over the years, urbanization has taken over much of the farmland surrounding the Greater Toronto Area and subdivisions now cover many areas where farms once stood.

Rouge National Urban Park preserves large tracts of Class 1 farmland – the rarest, richest and most fertile in the country – including the only remaining farms in the City of Toronto. Having farmland close to the city provides a source of locally-grown food, which is fresh, seasonal, supports the local economy, and is more environmentally friendly than food imported from distant places. Although agriculture is not a traditional part of national parks in Canada, Rouge National Urban Park offers a unique opportunity for nature and agriculture to thrive together.
