East York

At the end of 1933, Williams was elected to and served a one-year term as alderman on the East York Town Council for 1934.^[2] That same year, Williams ran for the Ontario legislature in the 1934 provincial election as the Ontario CCF candidate in York East, the personal constituency of Premier of Ontario George Stewart Henry, and won 21% of the vote (30% in East York Township) coming in third place.^[3] His 6,086 votes were the best result of any CCF candidate in the Toronto area.^[4] He also ran for the House of Commons in York East (the federal riding that included East York) during the 1935 federal election for the national CCF but was defeated by Conservative Robert Henry McGregor and the Liberal candidate.

One of the Association's campaigns led by Williams was to convince the East York town council to issue poor relief in the form of cash instead of vouchers. After the council agreed to issue cash instead of vouchers but reduced the value of relief payments the Association organized a "voucher strike" to raise the payments. Council reversed its decision and the Association retaliated by encouraging members to pull their children out of school which had the effect of reducing the provincial government's grant to East York. The Council then capitulated to the Association's demands only to have the Bank of Nova Scotia refuse to grant the municipality a loan which in turn caused the council to end cash relief and return to vouchers. In December 1935, Williams was elected reeve of East York.^[5]

However, Williams was more than three months in arrears in his rent and had to defend his right to take office as the provincial government had passed a law prohibiting anyone owing more than three months rent from holding office. A new election was scheduled but as no other candidates ran, Williams was acclaimed. The Workers Association under Williams also organized to block bailiffs from evicting families from their homes. The blocking of evictions had the support of many residents and Township officials, no matter their political views. Williams lost the reeve's office when he ran for re-election in the December 1936 election but the Township's council continued to support the policy of blocking evictions and set a licensing fee for bailiffs and then refused to issue licences for two months giving families threatened with eviction a reprieve.^[5]

According to a local historian, "If a member of the Workers Association caught wind of an eviction about to take place, they would telephone other members and yell to their neighbours on the street "eviction." Members would race by foot or by automobile if one were available to the house where the eviction was to take place. As the bailiff would remove the family's furniture from the house, members of the Association would politely carry the furniture back into the house."^[5]

Provincial politics

At the 1936 convention of the Ontario CCF, Williams filibustered against a resolution opposing a united front between the CCF and the Communist Party of Canada and was threatened with expulsion from the CCF for his behaviour.^[6]

Williams ran for the Ontario legislature in the 1943 provincial election and was elected from the riding of Ontario, which covered Ontario County (now part of the Regional Municipality of Durham).^[7] He sat as an Ontario CCF Member of Provincial Parliament for two years until he and most of the CCF's MPPs went down to defeat in the 1945 provincial election.^[8]

Federal politics

In 1948, he ran in a federal by-election in the riding of Ontario, which occurred following the death of Liberal MP W.E.N. Sinclair, and won. He served for a year until he was defeated in the 1949 federal election when he came in third place.^[9]
