Sun Life is a publicly traded Canadian financial services organization and one of the country's oldest insurers. Headquartered in Waterloo, it operates across 28 markets and serves more than 85 million clients worldwide. The company says it became the number one provider in the Canadian group benefits market in 2010.
The firm began as a Montreal insurance company in 1865, founded by local businessman Mathew Hamilton Gault. Poor economic conditions delayed the start, so the company opened for business in 1871.
It launched under the name Sun Mutual Life Insurance Company of Montreal. The company adopted its enduring operating name, Sun Life Assurance Company of Canada, in 1882.
The firm expanded well beyond Canada's borders within decades of its founding. By 1920, it operated in 55 countries, including Hong Kong, the UK, and the Philippines.
Back home in 1919, the firm says it became the first company in Canada to offer group life insurance. It grew quickly into a major provider of group benefit plans in Canada and the US.
Sun Life became a mutual company in 1962 after a process that bought back all outstanding shares for $65 million. Policyholders then voted in 1978 to shift the corporate headquarters from Montreal to Toronto.
In 1982, the company acquired Massachusetts Financial Services (MFS), a Boston-based investment manager founded in 1924.
The company reversed its mutual structure in 2000 and listed shares on the TSX, NYSE, and Philippine Stock Exchange. One year later, it announced a merger with Clarica Life Insurance Company, a Waterloo-based Canadian insurer.
In 2010, the company launched Sun Life Global Investments (SLGI) to bring investment products to Canadian plan sponsors and retail investors.
In May 2026, SLGI expanded its Granite target date fund lineup with a new predominantly passive option for Canadian plan sponsors. The launch extended SLGI's reach into passive strategies, more than 15 years after the original Granite series debuted.
Sun Life also added menopause care to its group benefits platform through a partnership with Dialogue, a Canadian digital health company. The program connects plan members to menopause-trained clinicians and personalized care plans through Lumino Health Virtual Care.
The company’s Canadian operations span group benefits, group retirement services, and investment solutions for employers and plan members:
Beyond these employer-facing products, Sun Life also offers individual Canadians term and permanent life, health, critical illness, disability, long-term care, and travel insurance coverage.
Jessica Tan serves as EVP and president of Sun Life Canada (SLC). Tan was co-CEO of Ping An and a McKinsey partner before moving to Sun Life. She holds a master's and two bachelor's degrees from MIT across electrical engineering, computer science, and economics.
Tan leads the company alongside a team of senior executives:
The leadership team operates under the oversight of Sun Life Financial Inc., its publicly traded parent. The company maintains a Code of Conduct that sets ethical and professional standards for all employees and advisors.
Sun Life says it serves more than five million Canadians across individual, group, and institutional markets. The company reaches plan sponsors and individual Canadians through nearly 2,700 advisors in more than 1,100 communities throughout Canada.
Regional offices across the country handle claims adjudication, disability management, and rehabilitation services for group benefits clients.
Sun Life's Group Retirement Services also tracks workplace savings data to support plan sponsors and advisors. In March 2026, the company published research on the gender retirement savings gap within Canadian workplace plans. It says women in its plans retire with an average of $164,000 saved, compared to $225,000 for men.
Plan sponsors and advisors can also find Sun Life listed in our Money Managers Directory and SRI/ESG Directory.
Sun Life has earned awards from Benefits and Pensions Monitor (BPM) and other organizations, alongside contributions to philanthropy and industry dialogue.
Sun Life's biggest community program focuses on diabetes prevention and care. Since 2012, the company has committed more than $64.9 million to diabetes-focused programs worldwide. In Canada, that includes partnerships with:
Company leaders also contribute to industry discussions through BPM. In 2024, Anne Meloche and Michael Carter joined a BPM roundtable on retirement income solutions for Canadian plan sponsors. That conversation addressed Canada's DC pension gap and retirement income planning challenges.
