in the city. Unlike James Simpson, Smith supported opening the CLP to members of the newly formed Communist Party of Canada. Joining the Communist Party Smith's personal philosophy continued to develop in this period, and in January 1925 he made the decision to join the Communist Party himself. His membership in the party was confirmed at a small upstairs room at 8 Gerrard Street East in Toronto, where a meeting of the party was held. He later explained his decision to a Toronto Star reporter by arguing that communism was a part of man's social evolution. Smith remained a member of the Communist Party for the rest of his life. Still a prominent figure in Toronto, he often defended the Communist Party against threats from hostile governments. He became a prominent organizer for the Canadian Labour Defence League across Canada in the 1920s, and served as its general secretary until it was shut down by the Canadian government in 1940. He campaigned for the House of Commons of Canada in the 1925 federal election as a candidate of the CLP in the northern Ontario riding of Port Arthur—Thunder Bay. He finished fourth, with 1,363 votes. The winner was William Fitzgerald Langworthy of the Conservative Party. At the time of the election, Smith described his occupation as "educationalist". He ran again in the 1926 election, and finished third with 1,382 votes. The winner was Conservative Donald James Cowan. Smith ran for municipal office in Toronto during this period.

He was defeated, and lost a second time in 1926. He also ran as a candidate of the Ontario division of the CLP in the 1926 provincial election, receiving 416 votes in Hamilton Centre.

He supported the removal of Maurice Spector and Jack MacDonald from the CPC, and endorsed Tim Buck, a strong supporter of Joseph Stalin, to become the party's new leader in 1929. In his autobiography, Smith accused Leon Trotsky of attempting to betray
