"The Hamilton Event Calendar was set up with the goal of becoming the be-all and end-all of events listings for our city. We do our best to include every event we can find, but we also allow anyone to upload and edit their own events -- so please help us achieve the pinnacle of completeness by uploading your events or any others that you know about."
