Linamar's Welland gigacasting project highlights Tier 1 risk in a weakening EV market

Linamar described the Welland project as part of its structural and chassis high-pressure die-casting strategy for electrified vehicles. In its March 2024 investor presentation, the company said it was the first supplier to invest in gigacasting technology in North America or Europe.

Unlike gigacasting projects implemented directly by automakers, the Welland facility was structured as an investment by an independent supplier. Such projects typically require long-term platform commitments from automakers because the casting equipment and tooling are designed for specific vehicle architectures.

Project scope and timeline

Linamar outlined the Welland project publicly in 2023. Redevelopment materials produced by King and Benton Redevelopment Corporation and regional documentation from the City of Welland describe plans to redevelop land at 59 Canal Bank St. into a large aluminum casting facility.

The company’s March 2024 investor presentation said the facility would house three 6,100-ton high-pressure die-casting machines. Construction information published by Kiwi Newton, the construction firm that led development of the project, also describes the plant as a 300,000-squre-foot facility designed to accommodate three gigacasting machines of that size.

An article published by the Society of Automotive Engineers (SAE) International, a professional association and standards organization for the automotive industry, described Tesla’s use of a 6,100-ton “Giga Press” supplied by IDRA Group to produce large structural aluminum components for the Model Y. Tesla’s adoption of the technology established its early use at scale in North American electric vehicle manufacturing.

At the time, presses in the 6,100-ton class represented the upper end of high-pressure die-casting equipment, in terms of clamping force, used in automotive manufacturing. More recent equipment catalogues from IDRA Group show machines in the 8,000- and 9,000-ton class.

Redevelopment site and parallel development activity

The Welland gigacasting facility forms part of a larger redevelopment of a former Union Carbide industrial complex.

Documentation from a 2024 Brown Awards finalist submission, a Canadian brownfield redevelopment program organized by the Canadian Brownfields Network, describes the site as a 260-acre industrial complex that operated between 1906 and 1999.

At the time of submission, redevelopment plans had already shifted toward recovering graphite from landfill materials identified on the site. Regulatory approvals allowed those materials to be processed for industrial use, including battery applications.

Those graphite-related approvals and development plans were associated with 65 Canal Bank St., an address linked to ReGen Resource Recovery and entities affiliated with the site’s developer, King and Benton.

Municipal property records separately identify the gigacasting facility at 59 Canal Bank St. as a roughly 36-acre parcel within the same industrial complex. That parcel size aligns with the footprint of the casting facility described in Linamar’s development materials.

Environmental filings describing aluminum casting operations reference the 65 Canal Bank St. address, placing both activities within the same broader redevelopment area, but under distinct project scopes.

The timing indicates that graphite recovery plans were already advancing during the period when the gigacasting facility was being constructed. Subsequent developments suggest that activity associated with those plans expanded to incorporate the casting site, replacing its originally intended use.

Marketing of the facility and joint venture announcement

Marketing materials from Cushman & Wakefield, along with an industrial property listing published by the City of Welland’s economic development office, show that the newly constructed facility was offered for sale or lease.

Reporting by Automotive News Canada in early February indicated Linamar was exploring a sale of its newly built but unused gigacasting facility in Welland, providing a public reference point for the timing of those efforts.

Less than a month later, on March 3, Linamar announced its joint venture with ReGen Resource Recovery. Coverage published the same day by Automotive News Canada described the partnership as a means of utilizing the recently constructed facility.

The sequence suggests the Welland site is being repurposed under the ReGen partnership rather than developed for its originally intended gigacasting application.

Linamar and ReGen Resource Recovery did not provide additional detail in response to questions regarding the facility’s development, equipment status, and current or planned use, including whether the project had been tied to a specific customer program, whether the giga casting presses had been installed or commissioned, and how the facility is intended to be utilized under the new partnership.

EV market environment

The facility’s projected start of production in early 2025 aligned with a period of policy and market changes affecting both the aluminum and automotive sectors.

During the first months of President Donald Trump’s second term, the US government increased Section 232 tariffs on aluminum and later extended the measures to certain imported automobiles and auto parts that did not qualify under the United States-Mexico-Canada Agreement. The section 232 duty rate on aluminum and its derivative products was later increased to 50%.

Later in the year, federal tax credits supporting electric vehicle purchases, including incentives of up to $7,500 for new vehicles, were scheduled to expire on Sept. 30, 2025, following congressional action. The incentives terminated for vehicles purchased after Oct. 1, 2025. Quarterly data show a sharper shift in demand following the expiration of federal tax incentives. US EV sales in the fourth quarter of 2025 declined by about 36% year over year.

Data from Cox Automotive indicates that US electric vehicle sales declined by an estimated 2% in 2025 compared with 2024, marking the first annual decline since 2020, despite remaining the second-highest year on record.

The annual figures include continued growth from newer market participants. Rivian increased deliveries by roughly 10,000 vehicles in 2025 as it continues to ramp production.

Established automakers also expanded their EV offerings. General Motors ranked second in US EV sales behind Tesla during the year, supported in part by a broader portfolio of EV models than in 2024.

However, the company attributed its fourth-quarter EV sales decline to elevated third-quarter results tied to pull-forward demand ahead of the expiration of federal tax credits. GM also indicated it was adjusting its EV strategy, including changes to its battery manufacturing footprint.

Public disclosures from General Motors show that several battery investments shifted during 2025. Of three previously announced battery plants that had reached construction completion and were intended for commercial production, one was repurposed for energy storage applications, another reduced its workforce towards the beginning of Q4 2025, and a third was divested.

Those changes were distinct from separate EV research and technology facilities and occurred alongside an additional battery plant that remains under construction.

Independent supplier risk

The Welland project illustrates the risk profile associated with gigacasting investments by independent suppliers, as opposed to projects implemented directly by automakers.

Large structural castings require specialized tooling and production cells designed for specific vehicle platforms. Supplier investments face greater uncertainty because production volumes depend on automaker program commitments.

While Linamar did not publicly link the Welland project to a specific customer or vehicle platform, the regional concentration of electric vehicle manufacturing suggests a limited pool of potential programs capable of supporting a dedicated facility of that scale.

A project built during a different investment cycle

Ontario’s automotive manufacturing footprint include several major assembly plants, including Stellantis’ Windsor and Brampton facilities, General Motors’ Oshawa and CAMI plants, Ford’s Oakville complex and engine operations, and Honda’s Alliston plant.

However, aside from a hybrid Chrysler Pacifica potentially produced at Stellantis’ Windsor plant, most of these facilities have not been central to large-scale electric vehicle production. The most notable exception was General Motors’ CAMI plant in Ingersoll, which had been positioned as Canada’s first full-scale EV assembly facility producing the all-electric Chevrolet BrightDrop delivery van.

General Motors confirmed in October 2025 that production of the BrightDrop at the CAMI plant would cease, citing weaker-than-expected demand and a changing regulatory environment following the removal of US tax incentives. Production at the facility had already been suspended earlier in the year, around the time of Linamar’s planned start of production.

Notably, Linamar announced its agreement to acquire Aludyne’s North American casting and machining assets in early October 2025, less than two weeks before General Motors confirmed the end of BrightDrop production at CAMI and stated that the program would not be relocated to another facility.

The timing places Linamar’s shift toward established casting operations alongside the cancellation of one of the few regional electric vehicle programs that could have supported large-format gigacasting.

Looking ahead

The Welland facility was developed during a period when gigacasting attracted attention across the automotive supply chain and when electric vehicle production plans expanded across multiple platforms.

By the time the project approached its planned start of production, policy changes, demand shifts, and program-level adjustments had altered those conditions.

The facility was completed but there is no indication it was commissioned for its intended use. It was later marketed for sale or lease and subsequently repositioned through a partnership tied to battery materials.

In that context, the project reflects the timing of supplier investments made under earlier market assumptions and the constraints of aligning large, platform-specific production assets with a smaller and shifting set of electric vehicle programs.
