Hedley will be in the Nickel City Wednesday night and as of March 13, approximately 2,100 tickets are said to have been sold.
That figure is down significantly from the approximate 2,400 tickets that the city had reported as sold on Feb. 28.
Approximately 200 tickets have been refunded in the past two weeks.
An official for Greater Sudbury has said that tickets continue to sell.
In an exclusive interview published by the CBC in late February, an Ottawa woman came forward with accusations that Hoggard raped her after she willingly travelled to Toronto to meet the singer.
A second woman has since gone public with allegations that Hedley frontman Jacob Hoggard pressured her to perform sexual acts without her consent in a Toronto hotel room in March 2013.
None of the accusations have been proven in court. On behalf of his client, Hoggard's lawyer denied the allegations of the Ottawa woman, and Hoggard himself denied the claims made by the Toronto woman.
On March 1, local volunteer-led initiative She Matters released a statement to the media expressing disappointment when the city refused to cancel the concert. Similar requests were made by women in other cities where Hedley had been booked.
Both Sudbury Arena and The Aud arena in Kitchener explained to persons calling for concert cancellations that their venues have been subject to legally binding contracts with concert promoter Live Nation.
With the concert going ahead, She Matters has organized a peaceful protest scheduled to happen in front of the concert venue from 5:30 p.m. to 7 p.m. An event page for the demonstration has recently been created on Facebook.
"In respect to the planned protest, the City respects the right to peaceful protests," a representative of Greater Sudbury stated. "Our main priority is to ensure the safety of anyone attending events at any of our municipal facilities."
Ticket refunds are being made available until 6 p.m. Wednesday night.
