Environmental groups secure halt to impending destruction of Lower Duffins Creek Wetland

March 15, 2021

 Ontario government must halt legal attacks on planning laws and repeal MZO

For immediate release: March 15, 2021

Toronto, Ont./ Traditional territories of several First Nations including the Williams Treaties First Nations, Huron-Wendat, the Anishnaabeg, Haudenosaunee, Chippewas, and the Mississaugas of the Credit First Nation — Pickering Developments has committed to not destroy the Provincially Significant Wetlands and other natural features at Lower Duffins Creek in Pickering, Ontario. The commitment will remain in place until the Divisional Court hearing of the groups’ full Judicial Review application regarding the legality of the proposed development. 

Environmental Defence and Ontario Nature, represented by Ecojustice agreed to an adjournment of their Court application after negotiating a legally enforceable undertaking to prohibit any destructive activity of the provincially significant wetland and other natural heritage features. Later this morning the parties will ask the Ontario Divisional Court to review the commitment by Pickering Developments and make it enforceable through a court order. The groups reserved the right to return to Court immediately if any terms of the commitment by Pickering Developments are violated.

The groups’ move to seek a Court-ordered stop to the planned destruction became necessary after Toronto and Region Conservation Authority (TRCA) was legally forced by the Provincial Government to provide permission to issue a permit if conditions determined by the Board of Directors were met. No permit has been issued and certain conditions imposed remain outstanding. 

This turn of events comes on the heels of the abandonment of this site as a candidate location for a warehousing facility by Amazon Canada, a stated willingness by Steve Clark, Minister of Municipal Affairs and Housing to revoke or amend the MZO that purports to authorize destruction of the wetland, and an indication by the City of Pickering that they wish to reflect on the issue. 

To protect the wetland, the City of Pickering must now request the repeal of the MZO that purports to authorise destruction of the wetland and Minister Clark must keep his commitment to respect Pickering’s wishes.

Further, to secure the permanent protection of this wetland, and many other sensitive ecological sites and farmland across Ontario, the provincial government must remove Schedule 3 from Bill 257, now before the Legislature. Schedule 3 proposes to allow the Minister to use MZOs to override all provisions of the Provincial Policy Statement under the Planning Act, effectively eliminating all natural heritage protection under Ontario’s municipal planning rules whenever an MZO is used.

Laura Bowman, Ecojustice lawyer said:

“We are pleased to get the resolution our clients wanted without the need to argue the motion.  The wetlands will be protected by the undertaking to the Court until the decision in our clients’ Judicial Review. Our clients are continuing the Judicial Review to quash the MZO in the long-term.”

“The Ontario government has expressed a willingness to consult on a possible amendment to the MZO to protect the wetland and we expect that this consultation will include the public and First Nations so that a final resolution of this matter protecting the wetland from destruction can be achieved.”

Tim Gray, executive director, Environmental Defence said:

“We are glad to see the developer agree to a pause in their rush to destroy this key wetland. This victory shows the power of community members mobilizing to protect a place they value. However, the fight is not over until the Minister’s Zoning Order is repealed and our planning laws and rules are respected.”

“Lower Duffins Creek wetland’s destruction would be a disaster on its own but its loss would also signal that all wetlands, forests, and river valleys are beyond the protection of the law and at risk from rapacious developers.”

Caroline Schultz, executive director, Ontario Nature said: 

“There’s an insidious and accelerating pattern of undercutting environmental rules to facilitate reckless development projects in Ontario. Bill 257, which allows the government to ride roughshod over natural heritage protections, is the latest example. This war against nature has to stop.”   

“As we grapple with the dual crises of climate change and biodiversity loss, it’s unconscionable to pave over any of the Duffins Creek Wetland Complex. It would be contrary to the will of the community and the long-term interest of Ontarians, as the public outcry against the  destruction of the Duffins Creek wetland has amply demonstrated.”
