I'm sorry the library doesn't have a shredder for public use. Office Max will shred documents for a fee. Also, watch your local newspaper, often a business will sponsor a shredding day. Good Luck!
I just read in today's Canton Observer that Community Alliance Credit Union is holding a Shred-It Day this coming Saturday (August 7), from 9-1, at their Livonia branch (37401 Plymouth Road at Newburg.) You can bring up to four paper grocery bags of items to shred and need not remove staples or paper clips.
