Ookwemin Minising

Ookwemin Minising (pronounced Oh-kway-min Min-nih-sing) meaning “place of black cherry trees”[1] is a 40-hectare area in Toronto's Port Lands that has been converted to an island as part of Port Lands Flood Protection Project by Waterfront Toronto.[2][3][4][5]

To prevent flooding from the Don River, a channel was created to extend the river south and then west into Toronto Harbour providing another outlet and a more natural mouth for the Don River. The new channel creates the island, which is also bounded by the Keating Channel and Toronto Harbour. Mixed-use residential development is planned for the Island.[6][7][8]

Port Lands Indigenous Place Naming Initiative

[edit]

The island held several names as it was conceived and planned, including Villiers Island and Cousins Quay. In 2024, the island was permanently named Ookwemin Minising as part of the Port Lands Indigenous Place Naming Initiative. The initiative focused on honoring the historical and cultural significance of Indigenous peoples, particularly the traditional caretakers of the land, through the selection of a new name.[9]

Project

Plans for Ookwemin Minising show a greenbelt, and parkland, surrounding a developed central area.[8] The developed central area will be primarily residential, with up to 9,000 units planned.

The new channel has natural curves, river banks, and plants that provide habitat for migrating birds and wildlife. The channel empties into Toronto Harbour at what is now the Polson slip. The Keating Channel had mooring for multiple freighters. The island lies on former industrial land, first created through landfill. The area will be cleared but buildings considered to have heritage value will be preserved.[10] These will either be moved to higher ground, or left in declivities, when additional landfill will be used to raise the ground level two metres in the event of rare extraordinary flooding.[11] More recent structures will be demolished.[12] Some existing industrial uses were moved to the main shipping channel to the south.

Just south of Lake Shore Boulevard, Cherry Street was relocated slightly to the west with new bridges crossing the Keating Channel. The Cherry Street lift bridge was demolished to widen the Keating Channel to improve flood conveyance during large flood events.[13] The Don Greenway, a new river valley, was constructed south from the Don River, crossing Commissioners Street under a new bridge, before turning west into Toronto Harbour. This new channel allows high water from the Don River to flow move easily south by avoiding the 90-degree turn into the Keating Channel.[14][15][16]

Port Lands Bridges

[edit]
A view of the Commissioners Street Bridge in 2022, before the river valley was flooded.

Four new bridges provide three access points to Ookwemin Minising. All bridges were built by Cherubini Bridges and Structures in Dartmouth, Nova Scotia, at a total cost of CA$100 million. All three locations will have provision for future streetcar service, which may be a future expansion of the proposed East Bayfront LRT. All four bridges have the same esthetic design and each span have a curved steel dome (designed by CIG Architecture of the Netherlands) rising over the road surface. All bridge spans were pre-assembled in Dartmouth and shipped on a barge via the Saint Lawrence Seaway.[16]

The four bridges are as follows:[17][16]

  • The Cherry Street North bridges are two single-span, side-by-side bridges that replaced the Cherry Street lift bridge. One bridge is for road traffic while the other will be used by pedestrians and public transit vehicles. The transit bridge could initially carry buses but was designed for streetcars.[18]
  • The Cherry Street South bridge has three spans crossing a newly created channel to run south of and roughly parallel to Commissioners Street. The Cherry Street Strauss Trunnion Bascule Bridge lies further south on Cherry Street off the island.[19]: 25 
  • The Commissioners Street bridge has four spans and was placed over a man-made channel being built as a southward extension of the Don River. Because of Seaway limitations, the bridge was shipped in two sections and joined on site.
Bridge dimensions and weight[17]
Bridge Length Width Height Weight
Cherry Street North (transit) 57 metres (187 ft) 21 metres (69 ft) 10.21 metres (33.5 ft) 340 tonnes
Cherry Street North (road) 57 metres (187 ft) 10.21 metres (33.5 ft) 450 tonnes
Cherry Street South 111 metres (364 ft) 21 metres (69 ft) 11.15 metres (36.6 ft) 790 tonnes
Commissioners Street 153 metres (502 ft) 53 metres (174 ft) 10.16 metres (33.3 ft) 1,210 tonnes

There will be a provision for three additional bridges in the future:[17]

  • a second Commissioners Street bridge,
  • a second Cherry Street South bridge, and
  • a four span bridge at Lake Shore Boulevard.

On May 6, 2024, it was announced that another bridge called the Equinox Bridge will be constructed to connected the island to mainland Toronto. It will be in the shape of an "S" and have an array of fanning cables.[20]

Flood control

[edit]

The island is a product of Waterfront Toronto's Port Lands Flood Protection Project. In November 2024, after six years of construction Waterfront Toronto connected the Don River to the channel forming the new mouth of the river and the island, Ookwemin Minising.[21] Before this milestone water from the Don River made a 90-degree turn into the Keating Channel, creating a bottleneck for water and a risk of flooding.[7]

The new channel is the primary outlet for the Don River; the Keating Channel is a secondary outlet if the need arises; and the Don Greenway is a third outlet, located south-east of the Island. The Don Greenway is a spillway and wetland situated between where the new Don River channel bends from south to west and the Ship Channel. Normally, water in the Don Greenway will only come from the Ship Channel. However, if the new Don River channel cannot handle high water volumes, then that water would be allowed to flood the Don Greenway and flow into the Ship Channel.[6]: D 

History

[edit]
The site of Villiers Island and the rest of the Port Lands were originally a marsh which was dredged and filled with landfill around the turn of the 20th Century.

The island was first part of the "Ashbridge's Bay" wetlands around the original mouth of the Don River, connected to a sandbar that is now the Toronto Islands. By the turn of the 20th century, the marsh had become polluted, and the city filled it with landfill, and devoted it to industrial purposes.[22] Some of the early twentieth century landfill was polluted, contaminated with heavy metals or toxic chemicals. The industrial enterprises were also polluting, including acres of petroleum tank farms and berms of road salt.

The city had also canalized and straightened the lower reach of the Don River, so it flowed straight for 5 kilometres (3.1 mi) from Bloor/Danforth to what is now Lake Shore Boulevard, where it made a right hand turn and ran 1 kilometre (0.62 mi) west into the Keating Channel.[22] This right-hand turn caused a significant build-up of silt and debris that had to be removed by the port authorities regularly to minimize flooding of the surrounding area after a storm.

By 2000, the area around the mouth of the Don River had declined in usage and significant areas were vacant. These lands were not developable due to the cost of remediating the polluted lands, and the lack of flood protection. To "unlock" the area for development, Waterfront Toronto proposed to "naturalize" the mouth of the Don River.[22] In conjunction with this, berms were built at Corktown Commons. The area between the Keating Channel and the new naturalized mouth would become Villiers Island, to be redeveloped for a mix of residential and open space uses.

In 2007, Waterfront Toronto held an urban design contest to establish a plan for what was then called the Lower Don Lands Precinct. The competition was won by Michael Van Valkenburgh Associates’ (MMVA), which designed the precinct around a re-naturalized Don River.[23] A preferred design for the Don Mouth was adopted by the City of Toronto in 2014, and options presented for the Villiers Island/Cousins Quay Precinct Plan.[24]

In October 2017, the Port Lands Planning Framework and Villiers Island Precinct Plan were adopted by Toronto City Council. The Port Lands Flood Protection project is being funded by all three orders of government.[25][26] The design for Port Lands Flood Protection was established through an Environmental Assessment, approved in 2015.[27] The Villiers Island Precinct Plan establishes design and development objectives for the area. The plan was developed by Urban Strategies Inc. of Toronto, with support from Arup and other firms, with the City of Toronto and Waterfront Toronto.[19] In 2024, the precinct plan was updated to update the vision from a predominantly mid-rise community to a dense, urban neighbourhood to increase the amount of affordable housing.[28]

In November 2024, Waterfront Toronto announced it had completed the new mouth for the Don River and the new island that would formally be named Ookwemin Minising.[29]
