Donnie Snook, 40, is facing eight charges including sexual interference with a child under 16, possession of child pornography and making child pornography.
The Saint John Police Force says several people have come forward since Snook was arrested at his home on Jan. 9 and officers are investigating those complaints.
Snook, who resigned from his council seat last week, is scheduled to appear in court on Monday for a bail hearing.
He has not entered a plea on the charges.
Police say investigators are also working to identify alleged victims in computer images that were seized after carrying out a search warrant at Snook's home in the city's east end.
Snook was elected in 2008 and has been involved in community organizations including the Inner City Youth Ministry, which provides sports programs, mentoring, and lunches at three local schools.
