During John Diefenbaker's leadership of the Progressive Conservative Party, Balcer was his Quebec lieutenant and Deputy Leader of the PC Party.[2]
A few months before the 1965 election, he left his party and sat as an independent, saying, "there is no place for a French Canadian in the party of Mr. Diefenbaker."[3] In 1964, he had led a small group of PC MPs who broke with Diefenbaker and supported a new flag of Canada during the flag debate championed by the Liberal prime minister, Lester B. Pearson. He did not run for re-election in that year.
