Based in Canada, Lewis will oversee strategy and execution across risk management, corporate and commercial client segments, risk consulting services, and specialty broking. He will also work with national leadership teams to expand integrated capabilities spanning risk, reinsurance and capital, people, investments, and management consulting services.
He succeeds Sarah Robson, who remains CEO of Marsh Canada, and will report jointly to her and Michelle Sartain, president of Marsh Risk for the US and Canada. Lewis currently serves as chief commercial officer for Marsh Canada and head of specialty and industry for Marsh Risk Canada, and will retain his CCO responsibilities alongside the new role. A successor for his specialty leadership position will be announced later.
Lewis joined Marsh Risk in 2006 within the Workforce Strategies group in Australia, later leading that business in Hong Kong from 2013. He relocated to Canada in 2018 as national growth and industry leader, giving him nearly two decades of experience across multiple geographies and specialty segments within the firm’s global network.
Robson said his appointment comes at a pivotal time for clients navigating economic and geopolitical volatility, including shifting trade policy, regulatory change, and increasingly interconnected global risks. Lewis said he plans to build on the existing platform to deliver expanded innovation and client service across Canada.
The promotion aligns with Marsh’s broader strategic emphasis on advisory-led growth and cross-platform solutions. In recent years, the broker has expanded analytics, climate risk, cyber, and supply-chain advisory capabilities globally, while continuing to integrate its risk, consulting, and capital advisory offerings to provide enterprise-wide solutions for clients. Industrywide, large brokers have been investing heavily in data, modelling, and sector-specific expertise as clients seek guidance not only on insurance placement but also on risk financing, resilience planning, and balance-sheet protection.
Cyber risk remains a central driver of that demand. Marsh research indicates that nearly 66% of organisations worldwide plan to increase cybersecurity spending in 2026, yet surveys show only about 6% of executives believe their organisations are fully prepared for major cyber events. That preparedness gap has become a key growth area for brokers with advanced advisory capabilities, particularly in sectors such as digital infrastructure, data centres, and critical services.
The leadership change signals continuity rather than a shift in direction: Marsh is reinforcing its commercial leadership bench while doubling down on integrated advisory capabilities as complex risk exposures - from geopolitical instability to systemic cyber threats - continue to reshape client priorities.
