Diefenbaker and Pearson
John Diefenbaker and Lester Pearson shared the Canadian political stage from 1958 to 1967, serving as Prime Minister and Leader of the Opposition for the Progressive Conservative ("Conservative") and Liberal parties respectively.
1. Prime Minister Diefenbaker - Leader of the Opposition Pearson
John Diefenbaker served as Prime Minister from June 21, 1957 to April 22, 1963. Lester Pearson was the leader of the Opposition from January 16, 1958 to April 21, 1963.
Prime Minister Diefenbaker
John Diefenbaker led the Conservatives to an upset minority government victory in the 1957 general election, defeating Louis St. Laurent and the Liberals. Challenged by Lester Pearson, the new leader of the Liberals, Diefenbaker returned to the polls in the 1958 election to win the largest majority government in Canadian history to that time.
The Diefenbaker majority government was reduced to a slim minority in the 1962 election. Economic problems such as high unemployment and a devalued dollar contributed to Conservative losses.
1957 Post-Election Campaign Mail
Ottawa to Mistawasis, Sask., August 29, 1957
The Mistawasis First Nation is a Cree First Nation in Saskatchewan, Canada. Mistawasis is located about 70 kilometers west of Prince Albert. The Mistawasis post office was open from 1896 to 1929. Today, the mailing address for the First Nation is Leask, Saskatchewan, the closest post office.
The Ottawa General Post Office did not forward the letter to Saskatchewan. Since there was no Mistawasis post office, Ottawa returned the mailing advising "NO SUCH POST OFFICE IN OFFICE NAMED".
Note stapled to the letter
Had the letter been sent to the destination province it probably would have been delivered.
