Hamilton Rejects Data Centre Land Severance After Massive Community Protest

In a recent CBC News report, footage shows hundreds of Hamilton residents gathered outside city hall on June 4, chanting slogans against artificial intelligence while holding signs that read "Save Our Harbour." The video captures the eight-hour Committee of Adjustment meeting where more than 75 speakers addressed the panel and 1,688 written submissions were logged, creating what officials described as a possible record for public input on a single land-use application in the city's history.

Hamilton Rejects Data Centre Land Severance After Massive Community Protest

Hamilton, Ontario – June 5, 2026 — Hamilton's Committee of Adjustment has denied Slate Asset Management's application to sever 76 hectares from the 324-hectare former Stelco steelmaking site, after hundreds of residents descended on city hall to oppose the possibility of a hyperscale data centre being built on the harbourfront property. The decision, reached after more than eight hours of public testimony, marks a significant victory for community organisers who mobilised what city staff described as a record-breaking volume of opposition.

The Protest Unfolds at Hamilton City Hall

On June 4, organiser Nick Tsergas coordinated the demonstration outside Hamilton city hall, drawing several hundred residents to oppose Slate Asset Management's land-severance request for the former Stelco site. Participants chanted phrases including "f--k AI" throughout the afternoon and into the evening as the Committee of Adjustment deliberated inside the council chambers at 71 Main Street West.

The gathering included residents from across Hamilton wards as well as visitors from neighbouring Burlington, where similar data centre protests occurred earlier in 2026. Local Ward 15 council candidate Chase Alford addressed the crowd before entering the meeting, calling for mandatory water and energy disclosure conditions if any approval were granted. Burlington councillor and mayoral candidate Lisa Kearns also spoke at the event, urging the committee to deny the application outright to allow more time for legislative review at the provincial level.

Environmental advocate Adeola Egbeyemi joined the rally and highlighted risks to Hamilton Harbour water quality from the proposed 76-hectare data centre footprint. "My hope is that Hamiltonians see this as the beginning and buckle up," Egbeyemi told the committee. "I love this city."

Committee of Adjustment Delivers Its Ruling

After more than eight hours of testimony, Hamilton's Committee of Adjustment rejected Slate Asset Management's application to sever 76 hectares from the 324-hectare former Stelco lands located in the Hamilton Harbour industrial area. Committee member Reid stated that the site technically met existing zoning regulations, yet the volume of resident opposition influenced the final denial. "The site meets all the regulations for the severance, but because of residents — the way they came out today and voiced their opinions — I would like a motion to deny the severance," Reid said when the time came to vote.

Committee chair Melvin Switzer presided over the session and confirmed that the panel had reviewed all 1,688 written comments submitted prior to the June 4 deadline. The decision prevents Slate from creating a separate parcel for a potential hyperscale and enterprise data centre while leaving the remaining 248 hectares available for other uses under the Steelport mixed-use plan.

The ruling came despite data centres already being listed as a permitted use under the industrial zoning that applies to the former Stelco property. Slate's planning representative Gerry Tchisler of MHBC Planning argued during the hearing that the project would rely on existing Stelco infrastructure rather than require new municipal services. City staff and security turned people away from the council chambers as seating filled up ahead of the meeting.

Resident Concerns Highlighted During Hearings

More than 75 Hamilton residents spoke during the June 4 session, detailing worries about electricity demand from a large data centre potentially straining Ontario's grid during peak summer months. Speakers referenced the federal government's $2-billion AI strategy under Prime Minister Mark Carney, which promotes data centre construction across the country. Residents also raised concerns about the impact of AI on employment, creativity, pollution, and public health.

University of Toronto professor Shion Guha, who studies technology policy, told the committee that Canada is still developing regulations for data centre water usage and cooling systems while simultaneously building new facilities. "Guidance around public consultation on data centres and governance of how they use water is lacking," Guha previously told CBC Hamilton. Residents cited recent protests in Burlington as evidence that similar projects face growing opposition in the Greater Toronto and Hamilton Area.

Many submissions questioned how the 76-hectare parcel would affect the larger Steelport redevelopment vision, which envisions mixed residential, commercial and light industrial uses on the 324-hectare site. Waterdown resident Chase Alford, who is registered to run for council in Ward 15, told the committee he wanted conditions imposed including water and energy use disclosure. "I'm not asking you to end the data centre," Alford said. "I'm asking you to look out for the residents of Hamilton."

Slate Asset Management Maintains Its Position

Slate Asset Management stated after the June 4 decision that no final commitment had been made to construct a data centre on the severed parcel, and that the company would continue evaluating options for the former Stelco lands. Representative Gerry Tchisler emphasised that any future facility would connect to existing Stelco water and power connections rather than draw new resources from Hamilton's municipal systems.

The company noted that the 324-hectare site remains part of the approved Steelport mixed-use development plan, which already designates portions for industrial activities including data centres. Slate officials indicated they would review the committee's written reasons before deciding whether to pursue an appeal to the Ontario Land Tribunal. Slate has said it has not made any decision about building a data centre or who might store data in one, but believes it can operate such a facility in a way that will mitigate people's concerns.

Despite the denial, Slate confirmed that the remaining 248 hectares continue under active planning for other industrial and commercial tenants. The firm has not ruled out returning with a revised application that incorporates additional community consultation requirements.

Federal AI Strategy Shapes Local Debates

Prime Minister Mark Carney's $2-billion national AI strategy, announced in 2025, explicitly encourages construction of hyperscale data centres to support Canadian artificial intelligence research and industry growth. Hamilton's rejection on June 4 illustrates how federal funding incentives now intersect with municipal land-use decisions across Ontario. The federal government is promoting data centre construction, citing economic benefits and the ability to keep Canadian data within the country.

Professor Shion Guha from the University of Toronto noted during the hearing that Ottawa is simultaneously advancing data centre approvals while provinces and municipalities draft new environmental standards for energy and water consumption. The Hamilton case follows similar public pushback in Burlington, where residents blocked a comparable project earlier in 2026. Slate said the proposal is not about training AI, but about ensuring Canada has data storage capacity and access to high-performance computing.

Local organisers including Nick Tsergas argued that federal dollars should first support upgrades to existing infrastructure before new data centres receive land-severance approvals. The 1,688 written submissions referenced specific clauses in the Carney strategy that call for community benefit agreements, which were absent from Slate's application. CBC Hamilton asked Innovation, Science and Economic Development Canada whether the new federal AI strategy will include guidance for data centre development, but the department did not respond before publication.

Appeal Process and Provincial Implications

Slate Asset Management has 20 days from the June 4 decision to file an appeal with the Ontario Land Tribunal, which would review the Committee of Adjustment's ruling on the 76-hectare severance request. Any appeal would be heard under the Planning Act and could take several months to schedule given the volume of evidence already submitted.

Committee member Reid's comment that resident turnout directly affected the outcome may become a focal point during tribunal proceedings because the site meets current industrial zoning. Provincial adjudicators would examine whether the committee applied the correct planning criteria or gave undue weight to public opinion. If the tribunal overturns the denial, Slate could proceed with severing the 76-hectare parcel for data centre use while still operating within the larger Steelport framework.

Hamilton city staff have indicated they will monitor the appeal and may participate as a party if the matter proceeds to a full hearing. An unnamed Hamilton city councillor has already signalled interest in creating a specific municipal framework to evaluate future data centre proposals. Such a policy could address water intake from Hamilton Harbour, electricity sourcing, and employment impacts before severance applications reach the Committee of Adjustment.

What Happens Next

The Hamilton outcome on June 4 signals that community mobilisation can influence land-use decisions even when projects align with existing zoning and federal AI investment goals. Cities across Canada now face similar pressures as the Carney government advances its $2-billion strategy to attract hyperscale facilities. Lisa Kearns, who has declared she will run for mayor of Burlington, urged the committee to deny the application to buy time for elected officials to "unlock new legislative tools to address data centres."

Environmental advocates such as Adeola Egbeyemi argue that future applications must include binding commitments on water recycling and renewable energy sourcing before any severance is granted. The 324-hectare former Stelco site remains a test case for how post-industrial waterfront lands can be repurposed without repeating past pollution patterns. Hamilton is one of multiple communities in which residents have protested data centre projects, and the pattern suggests municipalities may seek stronger tools under provincial planning legislation.

Organiser Nick Tsergas stated that the record 1,688 submissions demonstrate residents expect meaningful consultation on projects that could consume significant regional electricity and water resources. The case continues to draw attention from other Ontario municipalities evaluating their own data centre proposals in 2026, and the coming weeks will reveal whether Slate pursues a provincial appeal or returns with a revised approach.
