Lunenburg Mayor Rachel Bailey says this term as the town's chief magistrate will be her last.
The civic politician made the announcement November 1, releasing a statement after she had taken time to reflect on her own "priorities and aspirations."
She plans to finish her term through to the 2020 municipal elections but will not offer as a councillor.
"I want to assure everyone that today, tomorrow, and every day for the rest of my term as mayor, I remain passionate about and committed to continuing to do my job to the best of my ability, alongside my fellow councillors," she said in the statement posted online. "It has been a privilege to work with a talented and devoted staff team, including recent retirees, whose dedication inspires me daily."
Bailey served a term as a councillor between 2008 and 2012 before her successful mayoral campaign, which saw her defeat Ron Stockton in a contested race.
She won 75 per cent of the vote in 2016 when she was re-elected for a second term, downing her competitor, David Penney.
"I thank my family, friends and colleagues for the tremendous support and inspiration they continue to offer me every day," Bailey said in the statement.
