In the
1929 municipal election, rather than running for re-election as alderman, East challenged his former federal rival James Douglas for the mayoralty. He was defeated handily, finishing second in a four-person race. He tried to return to aldermanic office in
1930 but finished sixth out of twelve candidates, missing the five available seats. Labour's rival, the Civic Government Association party, swept all seats but one (won by Labour's
Lionel Gibbs). East sat out the
1931 election, but made a successful run for alderman in
1932, when he finished fourth. In the
1934 election, there were six seats available due to
Rice Sheppard's resignation to run for mayor halfway through his term, and East finished sixth to become Labour's only elected alderman that election. He received only three votes more than James Ponton, the CGA's lowest-ranking candidate. In 1935, municipal politics in Edmonton began to re-align. Labour continued to run candidates, but for the first time they were up against
Social Credit candidates, many of whom had links to the political left and to Labour. Labour candidate
Margaret Crang and three SC candidates were elected in this election (source: Monto, Tom. Protest and Progress. Three Labour Radicals in Early Edmonton (Rice Sheppard, Harry Ainlay and Margaret Crang). Edmonton : Crang Publishing/Alhambra Books, 2011). Among these successful Social Credit candidates was East's brother
Elisha, who was elected in the
1935 election - making the pair the only brothers to serve on the Edmonton City Council at the same time. For his
1936 re-election attempt, East joined the newly formed United People's League. This proved a mistake;. He finished first among the UPL candidates, but fell far short of re-election, finishing eleventh in an election swept by the CGA-successor Citizens' Committee. James East, by then in his sixties, made no further attempt to return to elected office. ==Death==
