If the calendars are local to your machine (i.e under the "On My Mac" section in iCal) I suggest you try my application iCal Reply Checker.
Cal Reply Checker is an add-in to iCal for Mac OSX that gives the user options for how replies to meeting invites on local calendars that are sent with Mail are dealt with.
This application allows the option to block some, all or none of the out-going meeting event related emails sent with Mail. It also gives the option to edit the message in Mail before sending.
Note: iCal Reply Checker is not compatible with notifications sent by iCal using Exchange or CalDAV servers including the iCloud calendar.
iCal Reply Checker is shareware. Registration is £3 and can be done through the application. The application runs as a demo for 10 days before registration is required.

I was just experiencing this problem on Mountain Lion. The calendar I wanted to delete was on iCloud. So, I logged into iCloud from a web browser, and selected Calendar. On the current incarnation of iCloud Calendar the calendars are listed on the left. I selected the "Edit" link at the top of that list and chose delete. It indicated that the items would be deleted, but there was nothing about notifications. Then, when I went back to iCal on my Mac, I selected the calendar to be deleted, right clicked, and slected refresh...
It probably would have disappeared on it's own eventually. I'd be curious to see if theis works for others, so please confirm.

I'm also very interested in removing a calendar to rid myself of the "delete and notify" issue within hundreds of meeting invitations. When you deleted this calendar in iCloud, did it send notifications to the invitees in any of the calendar events?
