It is easy to dismiss what Gallagher Bassett is doing in the United Kingdom as a peculiarity of British legal regulation – something made possible by rules that do not exist on this side of the Atlantic, and therefore not Canada's problem. 

That reading is too comfortable. 

The claims and risk management subsidiary of Arthur J. Gallagher & Co. – a group that operates from approximately 40 locations across Canada, according to its 2025 annual report – has been systematically acquiring UK law firms since 2017. The third and most recent deal, announced in May, saw it absorb Mays Brown, a London boutique specializing in shipping and maritime law. Its UK legal team now numbers around 180 people. Its EMEA chief executive, Manan Sagar, says he is actively looking for more deals, with financial lines, professional indemnity, directors and officers liability and clinical negligence all on the acquisition list. 

This is not a bespoke British experiment. It is a proof-of-concept for a global strategy – and Gallagher Bassett already has a Canadian footprint from which to launch it, the moment Canadian regulators allow it. 

What the model actually is 

To understand what Gallagher Bassett is building, it helps to understand what problem it is solving. The insurance claims process, in its traditional form, is fragmented: an insurer instructs a third-party administrator (TPA) to manage a claim; the TPA eventually passes the legal work to an external law firm; the law firm manages the litigation; and the claimant waits, sometimes for a long time, while these separate organizations communicate with each other at their own pace. 

Gallagher Bassett argues that this fragmentation costs everyone. By owning both the claims management and the legal functions under one roof, the company can run them simultaneously rather than sequentially – liability specialists assessing a claim while legal counsel is already engaged, rather than the two working in relay. The result, it contends, is faster resolution and a lower total cost of claim for the insurer or corporate client that instructs it. 

Sagar has articulated this directly: "If you are just administrating a claim and then passing it across to a law firm to manage the legal side of it, in our opinion you are not acting in the best interest of the client."

DWF and DAC Beachcroft – two of the UK's largest insurance-focused law firms – have pursued the same logic from opposite directions, acquiring TPAs rather than having law firms acquire them. The destination is identical: an integrated claims and legal offering that eliminates the handoff friction between the two functions. 

Why it cannot happen here – yet 

In every Canadian province, non-lawyers are prohibited from owning or having an equity stake in a law firm. Unlike England and Wales, which introduced Alternative Business Structures (ABS) through the Legal Services Act 2007 – creating the regulatory framework that makes Gallagher Bassett's UK acquisitions possible – Canada has not enacted equivalent legislation. 

Ontario and British Columbia have been the most active in examining reform. The Law Society of Ontario has examined ABS proposals several times, most recently through a working group that described the current restrictions as having "negative consequences" for the delivery of legal services. British Columbia launched an ABS pilot project in 2021. Neither province has yet moved to permit non-lawyer ownership in a form that would allow a company like Gallagher Bassett to replicate its UK model here. 

The result is that Gallagher Bassett's Canadian operations – and those of every other large TPA active in the country – must do what UK players no longer have to: pass legal work to independent external counsel rather than retaining it in-house. The integrated model that Sagar describes as acting in the client's best interest is, in Canada, a regulatory impossibility. 

For now. 

The pressure building on that wall 

The case for ABS reform in Canada has been made repeatedly and has repeatedly stalled, in part because of well-founded concerns about conflicts of interest and lawyer independence. Those concerns are not trivial. When a law firm is owned by a claims management company that is itself engaged and paid by an insurer, the question of whether the lawyers in that firm are genuinely independent advocates – or quiet instruments of cost reduction – is not merely theoretical. The Solicitors Regulation Authority in England and Wales requires separately regulated status for each entity within an ABS structure, but critics argue that the Chinese walls between a TPA and its subsidiary law firm are more porous in practice than they appear on an organizational chart. 

The counter-argument, pressed by access-to-justice advocates and legal innovation proponents, is that the current model is not neutral either. Panel arrangements, bulk referral deals and preferred supplier relationships already create structural dependencies between law firms and insurers. Formalizing the integration, with appropriate regulatory oversight, may be more honest about the relationship than the current arm's-length fiction. 

What has changed in the years since those earlier Canadian debates is the scale and sophistication of the model being built offshore. Gallagher Bassett is not a startup testing a concept – it is a subsidiary of a $15 billion revenue group that has now completed approximately 780 acquisitions since 2002, according to its SEC filings, and that operates in roughly 130 countries. When it eventually turns its attention formally to integrated legal services in Canada, it will not arrive as a disruptor. It will arrive as an incumbent. 

The questions Canadian lawyers should be asking 

For litigators who sit on insurance defence panels, the Gallagher Bassett model raises an immediate question about the durability of those panel relationships. If the TPA that instructs your firm were to acquire, or be permitted to create, its own in-house legal capability, the referral stream your practice depends on does not get redirected – it gets absorbed. The work does not move to a competitor; it disappears entirely from the independent bar. 

For in-house counsel at Canadian insurers and large corporates, the model offers something genuinely attractive: a single accountable supplier, lower friction between claims and legal functions, and a consolidated relationship that, in theory, should reduce the total cost of claim. The trade-off is a degree of trust that the integrated supplier's lawyers will always put the legal client's interests first – including when those interests diverge from what is administratively convenient for the TPA. 

For law society regulators in Ontario and British Columbia – the two provinces most actively watching ABS developments – the Gallagher Bassett experience in the UK is a live case study in both the commercial logic and the governance risks of integration. The SRA's framework for regulating ABS entities is more than a decade old and has led to enforcement actions, disciplinary findings, and ongoing debate about whether independence is genuinely protected in integrated structures. Canadian regulators considering reform would do well to examine that record carefully before deciding which elements of the UK model to adopt and which to leave behind.

The signal in the strategy 

Arthur J. Gallagher is not a company that builds capabilities it cannot deploy globally. Its 2025 annual report explicitly states that M&A is a core pillar of its growth strategy alongside organic development, and its Canadian brokerage and claims management operations provide an established platform from which to expand. Gallagher Bassett's global head of M&A, Matt Foote, has described the firm's acquisition approach as "an integral part of our long-term growth plans" – language that does not suggest a UK-only ambition. 

The legal wall that currently separates Canada from this model is real, but it is not immovable. England removed it in 2007. Australia followed. The debate in Ontario and British Columbia is no longer about whether ABS is conceptually permissible – it is about when, and on what terms. 

Canadian lawyers who assume that debate will resolve itself slowly, in their favour, and at a comfortable distance from their existing practices, may want to look more carefully at what has happened in the past 18 months on the other side of the Atlantic. Gallagher Bassett acquired a TPA, a marine claims manager, a German maritime firm, and a London shipping law boutique – all while running a legal team that now rivals a mid-size Bay Street practice in headcount. 

The integrated model is here. It is just not here yet.
