Ring of Fire Regional Development
The Ring of Fire is one of Canada's most significant undeveloped mineral districts, located in the James Bay lowlands of Northern Ontario, approximately 540 kilometres northeast of Thunder Bay. The district contains deposits of chromite, nickel, copper, cobalt, platinum group metals, vanadium, and gold across an area with an active claim area described by the Ontario government as approximately 8,000 square kilometres. Multiple project proponents are advancing development, supported by government infrastructure commitments and Indigenous-led infrastructure programmes.
In January 2025, the Impact Assessment Agency of Canada and 15 First Nations finalised the terms of reference for a co-led regional assessment of development activities and cumulative impacts across the district. The same month, Ontario and Aroland First Nation signed a Shared Prosperity Agreement providing over CAD $90 million for infrastructure and transmission line planning.

The Ring of Fire comprises multiple mineral projects within the James Bay lowlands. The Ontario government has described an estimated mineral value of CAD $60 billion for the district. Development requires substantial infrastructure investment, including an all-season road network of more than 500 kilometres, a 230-kilometre transmission line, broadband connectivity, and community facilities.
The district spans the traditional territories of 15 First Nations, referred to by local First Nations as Kawana 'bi 'kag. Webequie First Nation and Marten Falls First Nation are co-proponents of the Northern Road Link, the segment connecting the broader road network to the mineral district.
Three principal project proponents are advancing exploration and development at various stages: Wyloo (Eagle's Nest nickel-copper-platinum group metals project), Juno Corp (exploration across approximately 5,796 square kilometres of claims), and several other companies, including New Age Metals and MetalQuest Mining, that have staked claim positions in the district since 2025.

The Ring of Fire has been under exploration and development planning since 2007. Noront Resources discovered the Eagle's Nest nickel-copper deposit in 2007 and the Blackbird chromite deposit in 2008. Cliffs Natural Resources subsequently acquired chromite properties, including Black Thor, Black Label, and a 70 per cent interest in Big Daddy, and spent approximately CAD $500 million on acquisition and development before indefinitely suspending the project in November 2013, citing infrastructure and regulatory obstacles. Noront acquired Cliffs' chromite properties in 2015. Wyloo, part of the Tattarang private investment group headquartered in Perth, Australia, completed its acquisition of Noront in April 2022, renaming it Ring of Fire Metals, and subsequently unified its operations under the Wyloo brand.
Wyloo
Wyloo is advancing the Eagle's Nest project, a nickel-copper-platinum group metals underground mine containing over 20 million tonnes of measured, indicated, and inferred resources. The Impact Assessment Agency of Canada describes the project as producing approximately 3,000 tonnes of ore per day with an expected mine life of 12 to 15 years. In February 2026, the IAAC determined that Eagle's Nest would not be designated for a federal impact assessment. Wyloo's feasibility study is underway. The company has signed a memorandum of understanding with the City of Greater Sudbury for a downstream battery materials processing facility, with construction intended to follow the Eagle's Nest mine.
Juno Corp
Juno Corp is a private, Ontario-based exploration company and the largest mineral claimholder in the Ring of Fire. As of January 2026, Juno holds approximately 29,956 claims covering 5,796 square kilometres, representing over 52 per cent of the district's mineral claims. In 2026, Juno commenced a CAD $20 million, 100-hole drilling programme described as the largest in the Ring of Fire in over a decade. Key exploration targets include the Vespa Critical Minerals Complex, covering titanium, vanadium, high-purity iron, scandium, and gallium, and gold discoveries at Big Thunder, Pluto, and North Edge.

Road Network
Ontario's accelerated plan, released in March 2026, comprises four road segments totalling more than 500 kilometres.
The Webequie Supply Road (107 km) will connect Webequie First Nation's airport to the McFaulds Lake area. The corridor is approximately 35 metres wide, accommodating a two-lane gravel surface industrial supply road with potential for future transmission lines and broadband. Webequie First Nation is the proponent. Provincial approval was granted in June 2026; the federal decision statement was issued on 25 June 2026. Construction is scheduled to commence June 2026, with opening targeted for November 2030.
The Marten Falls Community Access Road (approximately 200 km) will connect Marten Falls First Nation to the provincial highway system near Aroland and Nakina. Marten Falls First Nation is the proponent. The environmental assessment was submitted on 20 February 2026. The federal decision statement was issued on 31 August 2026. Under a November 2025 Community Partnership Agreement, Marten Falls First Nation receives up to CAD $39.5 million for community infrastructure. Construction is scheduled for August 2026, with opening targeted for November 2031.
The Anaconda and Painter Lake Roads connect Highway 643 to the proposed all-season routes leading toward the Ring of Fire. Upgrades commenced in August 2026 under the Aroland Shared Prosperity Agreement. Opening is targeted for November 2030.
The Northern Road Link is the connecting segment between the Marten Falls Community Access Road and the Webequie Supply Road, crossing the Attawapiskat River to reach the Ring of Fire mineral district. Marten Falls First Nation and Webequie First Nation are the co-proponents. The Terms of Reference were approved on 3 March 2023. The environmental assessment is under preparation. Construction is scheduled to commence spring 2028, with opening targeted for November 2031.

Greenstone Transmission Line
On 28 January 2026, Ontario designated Hydro One to construct the Greenstone Transmission Line, a single-circuit 230 kV transmission line, designed to support a future second circuit, running approximately 230 kilometres from the existing East-West Tie near Nipigon Bay to a new switching station in or near Aroland First Nation. The line is expected to be in service by 2032 and will provide 350 to 700 MW of additional capacity in Northern Ontario.
Seven First Nations along the Highway 11 corridor and around Lake Nipigon will have access to Hydro One's First Nations 50-50 Equity Partnership Model, providing the opportunity to invest in a 50 per cent equity stake in the transmission line component.

Broadband Connectivity
The Matawa Broadband project is providing high-speed internet connectivity to northern communities.
Ontario
Ontario has committed CAD $1 billion to Ring of Fire infrastructure. The 2026 Ontario Budget reiterated this commitment and called on the federal government to match or exceed it.
In 2025, Ontario passed the Protect Ontario by Unleashing our Economy Act (Bill 5), which among other provisions empowers the government to create special economic zones intended to accelerate mining development. The Ring of Fire was announced as the intended first such zone.
Federal
The federal government co-leads the regional assessment through the Impact Assessment Agency of Canada. In December 2025, Ontario and the federal government signed a cooperation agreement to coordinate assessment processes and reduce regulatory duplication. The IAAC committed to completing reviews of the Webequie Supply Road and Marten Falls Community Access Road in 2026, and both projects subsequently received their federal decision statements in June and August 2026 respectively.
Federal programmes supporting Ring of Fire development include the Critical Minerals Infrastructure Fund, extended through the First and Last Mile Fund (CAD $1.5 billion, 2026 to 2030), and the Critical Minerals Sovereign Fund (CAD $2 billion over five years from Budget 2025).

The primary regulatory framework comprises several concurrent processes. The Regional Assessment, IAAC Reference No. 80468, is co-led by the IAAC and the 15 First Nations. The terms of reference were finalised on 20 January 2025. The conduct phase commenced in early 2025. The interim report was submitted in February 2026. The final report and recommendations remain pending.
Individual infrastructure and mining projects proceed through their own environmental assessment and permitting processes. The Webequie Supply Road and Marten Falls Community Access Road have both received their federal and provincial approvals. The Northern Road Link is in the environmental assessment preparation phase.
The IAAC determined in February 2026 that Eagle's Nest would not be designated for a federal impact assessment.
Ontario's Bill 5, the Protect Ontario by Unleashing our Economy Act, 2025, introduced special economic zone provisions intended to accelerate development in the Ring of Fire.
