Marigold Infrastructure Partners Inc. was fined $120,000 [1] after a worker was seriously injured at an Edmonton construction site.
The penalty underscores the legal and financial risks contractors face when safety protocols fail on large-scale municipal projects. Because the Valley Line West LRT is a critical piece of city infrastructure, workplace safety lapses can lead to increased regulatory scrutiny and public pressure.
Alberta Occupational Health and Safety imposed the fine on May 26, 2026 [3]. The charges followed an investigation into an incident that occurred in June 2023 [2], when a worker suffered a serious injury while on the job.
The company is the primary contractor responsible for building the Valley Line West LRT, also known as the West Edmonton LRT extension [4]. Investigators found that the firm breached workplace safety regulations during the project's execution.
While the specific nature of the injury was not detailed in the regulatory filings, the $120,000 [1] fine serves as a formal sanction for the safety failure. The incident occurred during the early stages of the extension project, which aims to expand the city's light rail transit network.
Officials from Alberta Occupational Health and Safety said the company failed to maintain a safe environment for its employees. The resolution of the case concludes a multi-year process from the initial injury in June 2023 [2] to the final penalty issued this week [3].

This penalty reflects the strict enforcement of Alberta's occupational health and safety laws on high-profile infrastructure projects. The three-year gap between the 2023 injury and the 2026 fine demonstrates the length of the regulatory investigation process and ensures that contractors are held accountable even after the immediate incident has passed.
