Mercer Canada is a management consulting firm that operates under the broader Marsh group. The company works with employers, pension administrators, and institutional investors across benefits, retirement, and investments.
The firm's story starts in 1945 with William Manson Mercer in Vancouver. He launched William M. Mercer, Limited as an actuarial and benefits consulting firm. Marsh McLennan, a New York-based professional services company, acquired it in 1959.
Marsh McLennan restructured the organization in 1975 as a wholly owned subsidiary. By 1992, it sat within a broader holding company alongside two other global consulting businesses. The firm went through successive names over the following decade and became simply "Mercer" in 2007.
The United Nations called on Mercer in 2006 to help develop its Principles for Responsible Investment. That role pushed the firm deeper into institutional investing.
In 2013, the company bought PricewaterhouseCoopers' Canadian pension windup administration business. That deal gave the organization a direct foothold in DB plan terminations for Canadian sponsors.
The company brought its investment and retirement practices together under a single Wealth division in 2017. By December 2019, the firm's investment AUM had crossed $300 billion globally.
In 2024, Mercer became part of the expanded Marsh brand. The following year, the firm acquired O'Brien Wealth Partners, a wealth management company with $1.1 billion in client assets.
Mercer Canada advises employers and institutional investors across three main practice areas:
Beyond these three areas, the firm also advises on executive compensation, M&A transactions, and HR transformation for Canadian employers.
Teresa Palandra has served as president of Mercer Canada since March 2023. She holds FSA and FCIA designations and a BSc in actuarial science from the University of Toronto. Palandra has spent nearly two decades in investment and retirement consulting roles at the firm before taking the top position.
Palandra leads the Canadian leadership team that includes:
As a subsidiary of Marsh & McLennan Companies, Mercer Canada does not operate a standalone Canadian board of directors. Governance flows through MMC's parent board structure in New York.
Mercer Canada's client roster covers a broad range of organizations across both private and public sectors. These range from small businesses setting up their first group benefits plan to large pension funds. The firm focuses on plan sponsors and institutional investors with complex retirement and investment needs.
The company distributes its services through consultants based across its 12 national offices. Its retirement and investment teams work directly with plan sponsors on pension risk management, asset allocation, and funding strategies.
Its health and benefits arm, Mercer Marsh Benefits Canada, focuses on group benefits plan design and cost management for Canadian employers.
The firm operates from Halifax to Vancouver with offices in:
That footprint gives it direct access to plan sponsors and institutional investors across major Canadian markets.
Mercer publishes quarterly DB solvency data through its Pension Health Pulse. The tool tracks the median solvency ratio of 471 DB plans in its Canadian database. In Q1 2026, the firm warned that strong DB surpluses may carry long-term risks as more employers take contribution holidays.
The firm also co-produces the annual Mercer CFA Institute Global Pension Index. The index ranked Canada 15th globally in 2025 with a score of 70.4. Both tools give plan sponsors a regular read on pension health across Canada and beyond.
Mercer Canada has earned recognition for gender equity and consulting from several independent organizations. Its professionals have also appeared in Benefits and Pensions Monitor awards programs.
The firm is a founding partner of Women in Governance's Parity Certification program. Partner and Toronto careers leader Kelly Mawhinney was also featured as a subject matter expert in HRD Canada's 5-Star DE&I Employers 2023 report.
She advised organizations on building stronger diversity and inclusion programs, from needs analysis to targeted recruitment and employee working groups.
