Bellamy took a hiatus from politics, but when James McKinley resigned his seat in 1911 to protest the firing of two city commissioners. Bellamy, who declared his support for the firing of the commissioners, ran against him during the ensuing by-election and defeated him by 966 votes to 576. During this term, in late 1911, he would serve a stint as acting mayor of Edmonton. He did not seek re-election the following year. In the 1916 Edmonton municipal election, Bellamy initially announced intentions to once again run for mayor, but withdrew from the race when incumbent William Thomas Henry announced his plans to run for another term. He elected instead to run for alderman, returning for a final stint on council after the election, when he placed first of eleven aldermanic candidates, accumulating 4219 votes. This campaign he had focussed on the issue of taxation, proposing to lower taxes by postponing payments into a sinking fund, and to seek alternate methods of taxation. During the term, he would keep to his campaign promise and introduce a plan to council aimed at lowering taxes. Petitioned to do so, he once again resigned halfway through his two-year term to run for mayor. He ran again on a platform of reducing taxation, but finished fourth of five candidates in the election. He did not return to political life thereafter.
