Our hearts are with our friends at CORE Burlington.
From their page:
Today we got the news we wished would never come. Like so many of you, we opened our email this morning and our hearts just sank. 130 pages to justify the approval of the quarry expansion we all know will hurt our community deeply, and today especially, our community is deeply hurting.
We need time to digest the 130 page Ontario Land Tribunal decision, review it in detail, and determine a path forward. We will be sure to reach out to you shortly once we have thoroughly reviewed the decision and consulted with our legal team.
This news has traveled quickly, and we’re in alignment with Mayor Meed Ward and the City of Burlington, as they expressed their disappointment with the OLT decision. But like us, their commitment to evaluating next steps shows what tremendous resilience our city, its residents, and our community has.
We want to thank you for all your support of CORE Burlington over the years, through thick and thin, the ups and downs, the good news and the bad. From the bottom of our hearts, we appreciate your unwavering commitment to protecting this incredible community and the breathtaking landscape we have up here on the Mount Nemo plateau.
We have included our response to the local and provincial media, which you can read below. We know there are no words that will do justice to the injustice we are all feeling, but we hope that this signals to all those watching that this decision is not something our community will be taking lightly.
OFFICIAL STATEMENT
Burlington, Ont. — Conserving Our Rural Ecosystems (CORE Burlington) is extremely disappointed with today’s decision by the Ontario Land Tribunal (OLT) approving the proposed expansion of the Nelson Aggregates quarry at Mount Nemo.
The decision approves a major expansion of an existing 500-acre quarry despite extensive evidence presented during the five-month hearing raising serious concerns about drinking water, air emissions and pollution, blasting, flyrock and community safety. These concerns are particularly significant given the quarry’s proximity to local homes, groundwater-dependent residents and environmentally sensitive areas.
The decision also raises serious questions about the reliance placed on provincial oversight and enforcement to protect the community. Evidence presented at the hearing, including the Auditor General’s findings, raised significant concerns about the effectiveness of regulatory monitoring and enforcement at Ontario’s quarries. Yet the decision repeatedly relies on future oversight by the Ministry of Natural Resources and other provincial agencies to address potential impacts.
CORE Burlington is deeply concerned that the decision does not adequately reflect the significance of what is at stake on Mount Nemo including the protection of drinking water, public safety, sensitive ecosystems and the community that calls this area home.
CORE Burlington is reviewing the decision and will provide further information on potential next steps, including a possible appeal.
“CORE/PERL, Burlington and Halton Region all presented compelling evidence at the hearing demonstrating that the expansion of the Nelson quarry will cause dangerous air emissions, threaten our drinking water and expose people to unregulated blasting and flyrock. Nothing in the decision addresses these public health and safety concerns, except to say “trust” the Ministry of Natural Resources (MNR) with the enforcement of standards that the Auditor General reports MNR systematically ignores" - Gord Pinard, President of CORE/PERL.
“Public trust in the process of approving the Nelson quarry expansion requires careful consideration of the major issues presented, particularly regarding the credibility of Nelson’s evidence. The evidence at the hearing, including the Auditor General’s report, strongly pointed to the fact you cannot trust Nelson or a number of their experts. The Ministry of Natural Resources (“MNR”) is not monitoring and enforcing compliance at Nelson Aggregates and all of Ontario’s quarries. Yet the Tribunal decision falls back on MNR oversight time and time again in the decision, even though MNR didn’t even review the final Adaptive Management Plan or Site Plans. This decision is far too accepting of MNR and MECP’s obvious failures.” David Donnelly, one of Canada’s leading environmental lawyers.
Today’s ruling by the Ontario Land Tribunal to allow the Nelson Quarry expansion is disheartening and contrary to the submissions from the city and community. Staff will review the decision and advise on options.
