I'm afraid that you can't get your hopes up. We went there last month for the same purpose. We asked some guests from the wedding that day about the property. They said that the property might be up for sale.
If you are from that area/ looking around that area. I would suggest you to try Parkwood Estate in Oshawa. It has an absolutely stunning ground with a history building as a backdrop. The garden is very well maintained and it has a fountain at the sunken level. I believe Kings Court is their caterer.
