It goes without saying that the Right Honourable Lester B. Pearson achieved much in his life. Whether you look at his success politically, academically or even athletically—Pearson always excelled. Although Pearson served as Canada’s 19th prime minister, his legacy and indeed his influence began long before his prime ministership: as chairman of the NATO council (1951), as President of the United Nations General Assembly (1952), and as a Nobel Peace prizewinner (1957).
“Nevertheless, [Pearson’s] five-year legacy is very impressive: a new flag, the Canada Pension Plan, universal medicare, a new immigration act, a fund for rural economic development, and the Royal Commission on Bilingualism and Biculturalism which led to the foundation of a bilingual civil service.”

Rising quickly through the ranks and moving from one portfolio to another, Pearson proved himself a worthy and talented diplomat. After a 20-year career in External Affairs, his success did not end there, but followed him throughout the next decade as leader of the Liberal Party (1958-1968). Without a doubt, some of his most exciting—if not his most significant achievements—came during his time as Prime Minister.
A flag for Canada
The quest for a Canadian flag—one that represented everything that Canada had become in the last century and all that Pearson hoped it could become—was fraught with bitter debate and controversy. Indeed, as many may recall, “The Great Flag Debate” raged for the better part of 1964 and saw the submission of approximately 3,000 designs by Canadians young and old.
“Under this flag may our youth find new inspiration for loyalty to Canada; for a patriotism based not on any mean or narrow nationalism, but on the deep and equal pride that all Canadians will feel for every part of this good land.”

These words, spoken by Lester B. Pearson during the inaugural ceremony of the Red Maple Leaf flag on February 15, 1965 at Parliament Hill, highlight precisely what he aspired to achieve—a uniquely Canadian identity. Few prime ministers can attest to leaving a legacy so great as to have forged an entirely new cultural symbol for their country.

A year of celebration
Not only was Pearson responsible for championing a new Canadian flag, but he was also lucky enough to remain in office during Canada’s centennial year. In his Dominion Day speech on July 1, 1967, Pearson called on Canadians to celebrate their past and their achievements, but also encouraged them to think of the future and of the legacy that they could leave for the next generation of Canadians. Much like this year, when we celebrated Canada’s 150th anniversary of Confederation and were encouraged to think of our future as a nation, 1967 was also a year filled with celebrations.
The aim of the centennial celebrations were twofold: to create memorable events and activities for all Canadians and to create a tangible legacy that current and future generations could enjoy. In fact, both the provincial and federal governments encouraged Canadians to celebrate by creating their own centennial projects—films, parades and festivals, tattoos, recreation centres, stadiums, etc.—and agreed to match their spending. One of the most memorable celebrations was that of the 1967 International and Universal Exposition or Expo 67, as it was nicknamed. Open from April 27 to October 29, Expo 67 is considered one of the most successful World’s Fairs and one of Canada’s landmark moments.

For many Canadians, 1967 characterized the peak of nostalgia and indeed a year filled with optimism. With this optimism and increased governmental spending, Pearson’s popularity boomed and further solidified his accomplishments as prime minister and widespread support for the Liberal Party amongst Canadians.
Conclusion
Forty-five years ago, on December 27, 1972, after a long and successful political career, Lester B. Pearson passed away. His passing struck a chord with many Canadians as more than 1,200 people attended his funeral service to pay their last respects. Pearson’s legacy and indeed his name are still present today in the numerous awards and buildings named in his honour. Paving the way for what many Canadians and the international community alike have come to love about Canada, Pearson can be said to have shaped and indeed laid the foundation for the Canada we know today.

Thank you for the reminder of Lester Pearson’s legacy.. With his keen sense of the importance of preserving the records of our history, Pearson transferred his papers to the Archives almost as soon as he left office. I remember spending most of the summer of 1968 in the basement vault of the Archives working on the Pearson Papers.
Nothing to be proud of!
Lester Pearson, like his protege P.E. Trudeau were closet Communists or had strong sympathies for Communism. Pearson was investigated for links to Soviet intelligence services operating in Canada and the United States under the auspices of the Communist Party of the USA and the Labour Progressive Party in Canada (formerly the Communist Party of Canada). He was fingered by the famous Soviet defector and GRU agent Elizabeth Bentley. Igor Gouzenko also had his suspicions of Pearson. What is most interesting is that many of the files that could clear up any suspicion are still completely closed to the Canadian public and held by CSIS. The same goes for files pertaining to Trudeau as well as a cavalcade of other so-called Liberals suspected of either Communist sympathies or direct contact with Soviet agents. One has to ask one’s self. If there is nothing to hide and these people are perfectly innocent, why cant the public access these records???? For example Pearson died 45 years ago! We can access the personal service records of our veterans but we cant access personal records of politicians? What makes them more sacrosanct?
Thank you for the wonderful article about Mr. Pearson, the greatest Canadian! Just a correction, Mr. Pearson was Canada’s 14th Prime Minister.
