 C.Y.O. Receives Platinum Award for Best Summer Day Camp!

Readers Choice Award 2014


The C.Y.O. is thrilled to announce that our summer day camp program – Camp Marydale, was awarded the Hamilton Spectator’s Platinum Readers’ Choice Award for favourite summer day camp.  Camp Marydale was the only summer day camp to receive Platinum, the highest level of recognition.  Thank you to everyone who voted and to the 2,300 children and their families who attend Camp Marydale this past summer.   It’s hard to believe, but staff is getting ready for another fun-filled summer and our new easy-to-use camper registration form will be available soon.
