Moffatt announced he was not running for re-election in the 2022 Ottawa municipal election, leaving the seat open, and Brown decided to run to replace him. His election priorities included repairing rural roads, upgrading infrastructure in the ward's villages, and "refocusing council's attention on addressing the basic needs of rural residents".[9] He also called for an "'independent budget watchdog' to scrutinize city spending", "figuring out an alternative to [the] waste disposal practice at the Trail Road dump", and to "respect taxpayers".[2] In the election, Brown defeated entrepreneur and educator Leigh-Andrea Brunet by over 4,000 votes, winning nearly two-thirds of the vote.[6]
Following his election, Brown was named Vice-Chair of the Audit Committee, and was named to the Agriculture and Rural Affairs Committee, the Environment and Climate Change Committee and the Committee of Revision. He was also named to the City of Ottawa Superannuation Fund.[10]
