1 Downsview Park 2 Natural Heritage Tour 7 6 Connect with Toronto’s urban wilderness 3 and explore the unique history of this 5 park –its transformation from a military base to a green space that is home to urban agriculture and environmental stewardship programs. Learn about the park’s natural characteristics and how they represent diverse landscapes, such 4 as the rare tallgrass prairie.

Downsview Park is a 291 acre parkland that integrates a mix of forests, ponds, trails, active and passive play areas, sports fields, gardens and related uses. The Park is home and often hosts various active uses year-round. Tenants located in the business sector of the site add various amenities with diverse programs, activities and services. Indoor and outdoor third- party events held in various locations in Downsview Park draw tens of thousands of visitors each year.

Downsview Park is the 291-acre parkland component of the site, completely separate from any development undertaken in the Downsview Lands.

(2019) Pg. 3 Stop #1 (c) Early Days of Downsview Park In 1994-1995, the federal government decommissioned the Canadian Forces Base Toronto and announced that the land would be set aside for development, recreational and broader public uses rather than be sold as other bases were. CFB Toronto formally closed on April 1, 1996. Parc Downsview Park Inc. was established in 1999 to build and operate Downsview Park yet it wasn’t until administrative control over the land was transferred to the Park in 2006 that significant steps could be initiated for the development of Downsview Park. The Park will continue to evolve over time as Canada Lands Company strives towards fulfilling its mandate of reintegrating this former military property into the fabric of City of Toronto.

These trees can be viewed as an investment in our shared natural heritage, an act for future generation. This area was one of the Park’s first to be re-naturalized. One thousand native trees were planted including: white Spruce, American elm, Silver Maple, Bur Oak, White Ash, Black Walnut, Trembling Aspen, and iron wood as well as Grey Dog wood , Downsview Park Tour Park Heritage Natural Downsview Fragrant Sumac, chokecherry, serviceberry, and staghorn sumac A north facing before and after view of a 2001 tree planting site at Downsview Park. Pg. 5 Stop #3 (a) Land Moved by Ice Downsview has a combination of silty clad and clay soils that tends to be heavy in texture and poorly drained. Much of Downsview’s soil is made up of a glacial till deposit that is part of the larger Halton till sheet from the Wisconsin glacial stage. The Wisconsin Glaciation is the most recent glaciation in the Toronto region. It began 100,000 years ago, burying the region below the Laurnentide Ice Sheet, and ended approximately 10,000 years ago.

Right: an aerial view of Downsview in 1969 Pg. 6 Stop #3 (b) Human Connections to Soil During the 20th century a number of buildings and roads were constructed to support Downsview’s expanding aerospace and military industries. These buildings resulted in significant soil compaction, limiting how much water and oxygen could penetrate the ground. The forest that surrounds us now used to be the location of a paved running track and turf field. Much of the Downsview site was maintained with short cut grass during the military years.

Pg. 7 Stop #3 (c) Downsview Soil Today Some ecological studies have described Downsview’s soil as “denser than concrete”. One study estimates that it would take 10,000 years for water to infiltrate a 10 metre unfractured layer of soil at Downsview Park. Some of the first park improvements at Downsview Park such as; planting of shrubs and trees and the re-establishment of native grasses, are slowly resulting Soil preparation work at in improved soil.

Downsview Park has worked to replace many of these pipes with a network of Bioswales: low areas of land that collect and channel water. The water that collects in Downsview’s bioswales are cleaned by natural materials like plants, rocks and soil. These materials also slow water which can help to reduce flooding in the Downsview Park Tour Park Heritage Natural Downsview Downsview neighbourhood.

The water is held in the lake for approximately 30 days before it is released into the Downsview Dells via a pipe underneath Keele St. After entering the Dells this water will eventually flow to Lake Ontario via Black Creek and the Humber River.

The silver maple, black walnut and locust trees planted by the Boakes are still with Downsview Park Tour Park Heritage Natural Downsview us today. Locust Lodge was built by the Boakes in 1860. This photo was circa 1896. Pg. 11 Stop #5 (B) Downsview Pre-European Settlement A 2001 City of Toronto study describes pre-European settlement Toronto as deciduous and mixed forests populated primarily by beech, maple and hemlock. Rodney Bobiwash, an Indigenous scholar, says that Toronto’s pre- European Natural systems existing in a pristine “undisturbed state” is an illusion. “There is much evidence that when European explorers first penetrated the interior of North America they found broad park-like forest areas. This led to the Downsview Park Tour Park Heritage Natural Downsview mistaken belief that North American forests were proto-forests, or primordial forests. In fact, the park- like forest expanses were carefully managed and cultivated Boake’s Grove in 2017 storehouses for Native people. “ Pg. 12 Stop #5 (C) Indigenous Peoples and Downsview Park Archaeological evidence does not necessarily reflect the history of Indigenous people as told through oral narratives and Creation Stories but they do help to further establish the point that different groups of Indigenous people have inhabited the Toronto area for at least 11,000 years. It is also important to recognize that indigenous people continue to live in Toronto today. The lands that now make Downsview Downsview Park Tour Park Heritage Natural Downsview Park was at various times part of Wendat, Haudenosaunee, and Pre-contact Aboriginal ceramics found at Downsview Park. These ceramics are Mississauga territories. consistent with Downsview’s site affiliation with the Huron – Wendat people ca. 800 - 1650 Pg. 13 Stop #6 (A) Downs “view” This hill was formed by re-using the soil that was excavated during the construction of the storm water lake. The term “Downsview” was coined by Caroline Amelia Carpenter in 1843 in recognition of the views created by the elevated topography found in the Downsview area. Caroline Amelia Carpenter was the wife of John Perkins Bull and grandmother of William Perkins Bull (author of From Oxford to Ontario: A History of the Downsview Community).

An estimated 3% of Ontario’s Tallgrass habitat is all that remains of this vanishing ecosystem. By recreating a Tallgrass prairie on 5 acres at Downsview Park, this project will educate local school children and a city-wide Downsview Park Tour Park Heritage Natural Downsview audience about the importance of biodiversity and habitat preservation.
