This month, incumbent Mayor Andrew King confirmed his intentions to stand for another term.

TOM LEE/STUFF Cr James Casson believes there should be a limit to the amount of terms a councillor can run.

Cr Geoff Taylor did not rule it out but former candidate and sitting councillor Paula Southgate said she was keeping her options open.

Deputy mayor Martin Gallagher confirmed he would stand again for council while Cr James Casson posted on his Facebook page that he would also run. Gallagher is not considering a mayoral bid.

"Yes, I'm running again, 3yrs is not enough but a limit should be placed in terms a councillor can run. 2 or 3 Max would ensure fresh ideas, prevent stale thinking and encourage participation [sic]," Casson said.

O'Leary said the city is at a crossroads.

"Leadership by surprise isn't working," she said. "Three short years ago the current Mayor campaigned hard on a platform of truth and transparency and it's deeply disappointing that his actions have totally failed to deliver on this promise

"Under current leadership, residents find themselves enduring soaring rates and see their city plunging further into a debt".

The 2019 local body elections will be held on October 12. Nominations open on July 19.

Clarification - A previous version of this story said Hamilton City Councillor James Casson was not considering running for mayor. Casson will make a decision at the end of the week and will announce his intentions on Sunday evening.
