Mayor Anne Monceaux has accepted the resignation of Councillor Julian Carbone, effective forthwith.
"The past few days of media coverage surrounding Councillor Carbone has taken its toll on many people," Mayor Monceaux said.
"I am deeply saddened, in particular, by the impact that this may have had on the young woman involved and more broadly, others within our community."
When presented with the findings of the Code of Conduct investigation on Tuesday evening, the Council resolved that Councillor Carbone give a written apology, undertake social media training and deactivate his social media.
"Two Council Members had called publicly for his resignation and the past 48 hours have shown that many members of the community support that," Mayor Monceaux said.
"I have accepted his written apology and resignation and am pleased that Council can now move on and continue the good work our Council members have been doing for our community."
