Canada’s infrastructure pipeline is currently moving hundreds of billions of dollars across transit, healthcare, and green energy megaprojects. But where there is unprecedented scale, there is inevitable friction. As public-private partnerships (P3s) and progressive design-build models face the harsh realities of 2026—marked by persistent supply chain bottlenecks, stringent new environmental regulations, and fluctuating labor markets—the demand for specialized infrastructure litigators has never been higher.

This reality was underscored recently when Sophie Perron of Montreal-based IMK was recognized in Lexpert's Special Edition: Infrastructure 2026 as a leading lawyer in the sector. While full-service national firms traditionally dominate the front-end structuring and financing of these megaprojects, Perron’s recognition highlights a crucial shift in the Canadian legal market: when multi-billion-dollar projects derail, clients are increasingly turning to specialized litigation boutiques to navigate the fallout.

The Rise of the Infrastructure Litigation Boutique

For decades, the standard playbook for Canadian infrastructure projects involved relying on a single national law firm to handle everything from initial procurement advice to mid-project dispute resolution. However, the sheer size and interconnectedness of today's projects have made this model increasingly difficult to sustain.

When a dispute arises on a major provincial transit line or a federal clean energy facility, the web of stakeholders—governments, prime contractors, engineering firms, and specialized subcontractors—creates a minefield of potential conflicts of interest for large full-service firms. This has created a lucrative opening for elite dispute resolution boutiques.

"The modern megaproject is a hyper-complex ecosystem. When a critical path delay occurs, you don't just need a litigator; you need an advocate who understands the granular mechanics of construction delay claims, surety bonds, and the specific statutory landscape of the jurisdiction, all without being conflicted out by ties to the project's financiers."

Firms like IMK in Quebec have built formidable reputations by stepping into these high-stakes disputes. Because they do not carry the massive corporate portfolios of their "Seven Sisters" counterparts, they are uniquely positioned to litigate aggressively against major institutional players when necessary. Perron’s inclusion in the Lexpert Infrastructure edition is a testament to the market's growing reliance on this boutique model for complex civil and commercial litigation.

Shifting Battlegrounds: What is Driving 2026's Infrastructure Disputes?

The nature of infrastructure litigation in Canada has evolved significantly over the past five years. While traditional disputes over scope changes and payment delays remain common, new catalysts have emerged in 2026.

1. The Transition to "Progressive" Contracting Models

To mitigate the risk transfer issues that plagued traditional P3 models, many Canadian jurisdictions have adopted progressive design-build or alliance contracting. While these models are designed to be more collaborative, they are legally untested in many provincial courts. When the collaborative framework breaks down, litigators are forced to argue over novel contractual mechanisms regarding shared risk and target-cost overruns.

2. Climate Resiliency and Environmental Compliance

With the federal government enforcing stricter environmental impact assessments and carbon-reduction mandates for public funding, project delays tied to environmental compliance have skyrocketed. Litigators are increasingly handling disputes centered on force majeure clauses and whether unforeseen environmental regulatory hurdles constitute compensable delays.

3. Insolvency in the Subcontractor Chain

Despite massive public investment, the economic pressures of high interest rates and inflation have squeezed mid-tier contractors. A single insolvency in the critical path of a megaproject can trigger a cascade of litigation involving lien claims, surety bond calls, and priority disputes among creditors.

Analyzing the Evolution of Infrastructure Litigation

To understand where the practice area is heading, Canadian legal professionals must look at how the primary drivers of litigation have shifted from the early 2020s to today.

Strategic Imperatives for Canadian Legal Professionals

For lawyers practicing in construction, commercial litigation, and public procurement, the current climate demands a highly strategic approach. The recognition of specialized litigators in national rankings signals a broader market trend that practitioners must adapt to.

1. Master Real-Time Dispute Resolution: Courts are no longer the primary venue for infrastructure disputes. Counsel must be adept at navigating statutory adjudication (such as Ontario's Construction Act regimes, which are rapidly influencing other provinces) and real-time project dispute boards. Litigators must be prepared to argue complex technical issues on expedited timelines.
2. Build Referral Networks with Boutiques: Corporate counsel and full-service firm partners must proactively build relationships with elite litigation boutiques. When a conflict of interest inevitably arises on a multi-party megaproject, having a trusted, conflict-free litigator on speed dial is a critical client service capability.
3. Integrate Technical Expertise Early: Infrastructure litigation is heavily reliant on expert testimony. Successful litigators are those who integrate forensic delay analysts, quantum experts, and engineering specialists into their strategy from day one, rather than waiting for the discovery phase.

Looking Ahead: The Maturation of Infrastructure Advocacy

As Canada continues its historic infrastructure build-out—from the expansion of Quebec’s transit networks to the revitalization of healthcare facilities across the Prairies—the legal framework supporting these projects will only grow more complex. The era of treating infrastructure litigation as a standard breach-of-contract exercise is over.

The spotlight on litigators like Sophie Perron in national industry rankings confirms that specialized, deeply technical dispute resolution is now recognized as a distinct and vital pillar of the infrastructure sector. For Canadian law firms, the message is clear: the ability to structure a billion-dollar deal is essential, but the ability to fiercely and surgically defend it when the ground shifts is what will define the legal leaders of the next decade.
