Acciona pays Metro Vancouver $235 million to end North Shore sewage plant legal fight

Metro Vancouver and contractor Acciona have ended their years-long legal fight over the North Shore Wastewater Treatment Plant through a $235 million settlement announced on May 13, 2026. The agreement, confirmed in a joint statement, directs Acciona to pay the Greater Vancouver Sewerage and Drainage District and resolves all outstanding lawsuits between the parties. Metro Vancouver said the deal clears the way for an independent review of the troubled project to move forward after being stalled for months during active litigation. The settlement marks a significant milestone in one of the region's most closely watched and costly infrastructure disputes, bringing a measure of closure to a contract battle that helped push the plant's total cost past $3.8 billion.

The Details

The wastewater plant, one of the region's largest infrastructure projects, began major construction in 2018 under an initial cost estimate of $700 million and a completion target of 2020. When work began, the facility was expected to serve North Shore communities within a predictable budget and timeline. Costs climbed steadily in the years that followed. By 2021, the budget had risen to $1.058 billion, already placing the project well above its original price. As costs mounted, relations between Metro Vancouver and its original contractor deteriorated. Metro Vancouver terminated Acciona's contract in 2022, removing the firm from the project entirely. In its place, the regional district brought in PCL Constructors and AECOM to finish construction. Major construction resumed in early 2024 under the new contractors, but the breakdown between Metro Vancouver and Acciona had already produced significant legal entanglements that would take another two years to untangle.

By March 2024, the total estimated cost of the project had reached $3.86 billion, more than five times the original estimate, and the completion date had been pushed back to 2030. The legal dispute between Metro Vancouver and Acciona over the project's management and cost escalation had also forced Metro Vancouver to suspend its planned independent review. The regional district paused the review in July 2025 while the lawsuits were still active, saying at the time that litigation made proceeding impossible. The May 13 settlement removes that barrier and explicitly allows the review to continue. Under the terms of the settlement, Acciona agreed to the $235 million payment, and both sides stated that the lawsuits have been resolved. The payment represents one of the largest contractor settlements in recent Metro Vancouver history and comes nearly three years after the firm was removed from the site.

Context

The cost overruns and delays at the North Shore facility have not stayed confined to the project site. The ballooning budget triggered wider political scrutiny of Metro Vancouver's governance and financial oversight, and the issue has become a persistent source of concern for ratepayers across the region. The burden has fallen especially heavily on North Shore municipalities, which are responsible for 37 percent of the project's costs. In response to the escalating price tag, municipal leaders in North Vancouver previously pressed the provincial government for a public inquiry and a broader governance review of the regional district. Local officials have repeatedly cited the plant's trajectory as evidence that the regional district's project controls need external examination, and the resumption of the review answers a long-standing demand from affected communities. Residents and municipal councils on the North Shore have tracked the project's budget closely, given their outsized share of the financial obligation.

What's Next

With the litigation formally resolved, Metro Vancouver's paused independent review of the program is set to resume. Metro Vancouver Board Chair Mike Hurley said in a statement that officials understand residents are watching closely. Hurley described the North Shore Wastewater Treatment Plant as "one of the most important projects currently underway for the health and well-being of this region" and added that Metro Vancouver is "very aware of residents' concerns about the project." The regional district has not released a specific timeline for when the review will issue findings, but its resumption marks the first concrete step toward addressing some of the underlying accountability questions since the lawsuits forced it to a halt last summer. The review's findings could influence how Metro Vancouver manages oversight of the remaining construction work and how the region handles similar large-scale infrastructure planning in the future. The project remains under construction with a targeted completion date of 2030.
