David Thomson is among the richest businessmen on the globe and is general chairperson of Thomson Reuters, a business that has grown into an international heavyweight in the areas of professional information services, legal technology, financial data and global newsgathering. Unlike many billionaire businessmen, who try to attract as much media exposure as possible, TOmson has established himself as one of the most discreet businessmen in the world, despite being the owner of an empire worth several tens of billions of dollars.
As the patriarch of Canada’s wealthiest family, David Thomson manages a family empire that can be traced back through past generations. The nation’s wealthiest family was originally created by his grandfather, Roy Thomson, who with limited resources established a media conglomerate. Over the course of many years, the Thomson family turned a few newspapers and broadcasting businesses into a global information enterprise. Consequently, David Thomson has been tasked to take the business forward into the digital age.

David Thomson has consistently ranked among the world’s richest individuals over the last several years. His fortune is primarily tied to the Thomson family holding company and its controlling stake in Thomson Reuters, along with numerous other investments spread across various industries.
Early Life and Family Background
Born as David Kenneth Roy Thomson in Toronto, Ontario, Canada on 12 June 1957, the man better known as Kenny was the son of one of Canada’s most prominent business families. His grandfather, Roy Thomson, had already made a name for himself as one of Canada’s best business minds by building up a media empire that encompassed newspapers, broadcasting stations and publishing companies.
By growing up in a wealthy family, David had opportunities that very few people get to have. Nevertheless, his family was very responsible, conscientious and they prioritized educating themselves and mastering the fundamental terms of business. Instead of enjoying the fruits of wealth, he was taught how business functions and how value can be created in the long run.
At a later time, these inaugural revelations would significantly influence how he approached leadership-and oversight of his wealth.
Education
David Thomson attended Upper Canada College, one of Canada’s most prestigious private schools. After completing his early education, he continued his studies at Selwyn College, Cambridge University in England.
At Cambridge, Thomson developed strong analytical and critical thinking skills. Although he did not study business directly, his academic background helped him develop a broad understanding of history, economics, and decision-making.
His education also exposed him to international perspectives, something that would later prove valuable as the Thomson family expanded its business interests around the world.
Taking Over the Family Empire
Unlike many self-made entrepreneurs, David Thomson inherited a business empire that had already achieved significant success. However, inheriting wealth and maintaining it are two very different challenges.
Throughout the 1980s and 1990s, he gradually became more involved in the family business. During this period, he learned about investment management, corporate governance, acquisitions, and strategic planning.
A major turning point came in 2006 when his father, Kenneth Thomson, passed away. David Thomson inherited leadership responsibilities and became chairman of Thomson Reuters.
The transition placed enormous responsibility on his shoulders. He was no longer simply a member of the Thomson family; he was now responsible for protecting and growing one of the largest fortunes in the world.
Building Thomson Reuters
Perhaps the highest point of David Thomson’s career came in 2008 when The Thomson Corporation finalized its purchase of Reuters Group.
Had the merger gone ahead, it would have merged Loudcloud with the world’s biggest professional information provider, financial data services, legal technology solutions, tax offering, accounting software provider and global news aggregation.5
It made the company a heavyweight competitive entity on the global stage.
Thomson Reuters did not compete in traditional media businesses but instead concentrated on delivering high-value information services for finance, legal, healthcare, accounting and government professionals.
This strategic movement enabled the company to stay profitable even while traditional newspapers and media companies suffered in the digital age.
Expanding Beyond Media
Thomson’s arguably greatest strength has been diversification.
Instead of relying solely on media companies, the Thomson Family diversified into many industries such as technology, finance, private equity, telecommunications, infrastructure and property.
These investments could decrease risk and could provide a number of revenue streams.
Today, the Thomsom family owns assets amounting to several tens of billions of dollars through Woodbridge Company Limited, their main investment holding company.
This diversified approach has been a key to conserving the family’s wealth through cycles of downturns and upheavals in the industry.
Challenges and Business Struggles
Handling one of the world’s largest family fortunes.
The media business was revolutionized by the internet age. Newspapers that ploughed billions of dollars in profits into the past were losing readers by the million and advertising.
But, for many traditional media companies, this was too little, too late.
Thompson reallocated his emphasis on information services and digital media. Instead of resisting the trends of change, he accepted and adapted to new technologies and customer expectations.
2008 was not only a crisis for people; it also brought great trouble to markets and many companies. Share price fluctuations had adverse impacts on investments and corporate clients and threw the economy into recession.
Undeterred by these challenges, it grew and consolidated its presence in major markets.
Throughout his career, this trait to acclimate to new circumstances has been a defining trait of David Thomson’s leadership.

Unlike many modern billionaires who actively seek publicity, he prefers to stay out of the spotlight.
His leadership philosophy focuses on:
- Long-term thinking
- Conservative financial management
- Strategic acquisitions

- Sustainable growth
This approach has allowed the Thomson family to preserve and expand its wealth while avoiding many of the mistakes that often affect large family businesses.
His success demonstrates that effective leadership does not always require constant public attention.
