Ward 2 councillor Andy Van Hellemond had decided to run again for council in this October's municipal election.
Van Hellemond, who had been leaning towards stepping back after serving two terms on council, submitted his nomination papers on Monday.
That leaves only Ward 6 councillor Karl Wettstein as the current member of council still undecided about whether or not they will run again. The 12 other members of the current council have either registered or have said they will be registering.
Deadline to register is July 27.
So far 23 people have registered to run for council and Mayor Cam Guthrie is the lone person registered to run for mayor to date.
Van Hellemond said he had thought about not running, but the residents of Ward 2 convinced him otherwise.
He is 70 and has seven grandchildren and thought maybe it was time to step down.
"The residents of the area have been overwhelmingly supportive," Van Hellemond said. "One day I had a group of four come over asking me to run again and another day I had a group of five come over asking me to run.
"It was very gratifying, to tell you the truth," he said.
He said two other people had told him they were thinking of running but wouldn't if he did.
In 2014 and 2010 Van Hellemond was the top vote getter of those running in Ward 2. Six ran in 2014, five ran in 2010.
Van Hellemond has a reputation as a councillor who doesn't say much at council meetings but one who works tirelessly to help out his constituents, helping them navigate the halls of City Hall in getting answers and problems solved.
"I've never been a big fan of the long meetings, but I've always loved helping people out. To me that's what a councillor is supposed to do," said the former National Hockey League referee who moved to Guelph in 1973.
He said there are a couple of project he would like to see through, such as the trail underpass and bridge work on Speedvale Avenue and a potential community hub being looked at for Brant Avenue.
"It may not be quite as active in Ward 2, but there's still some things happening," he said.
