The apology follows a somewhat ambiguous response he posted to the online White Rock Sun, of which he is publisher and editor, saying the comments were taken out of context and speculating the furor may have been politically motivated.
Now he says the remarks "were insensitive and for that I am truly sorry."
"In no way shape or form did I intend to marginalize or insult pregnant women or those that love them," he said in the statement. "This is a free world. Men and women can do and wear whatever they feel comfortable."
"I have learned the hard way as an elected official that I will now be held to a much higher standard. I am very sorry and wish to sincerely apologize to anyone who took any offence to my comments."
Chesney made the comments while discussing pregnant women's attire April 6, on Jim Goddard's on-line radio show, the The Goddard Report.
Chesney also read his apology at one of his community gatherings Saturday at White Rock's library where citizens have the opportunity to speak to him about problems facing the municipality.
At least one person who attended loudly criticized Chesney for his pregnancy clothing comments.
"He apologized if he offended anyone with his comments. He didn't retract his statements," said TJ Mair after leaving the meeting.
Meanwhile his Chesney's fellow councillor, Helen Fathers, hopes council can now move on from what she calls a distraction.
"I think it's a case of opening one's mouth and putting one's foot directly into it," she said. "It was very stupid what councillor Chesney said. We all make mistakes."
