World's Biggest Bookstore

The World's Biggest Bookstore is a bookstore owned by Chapters in Toronto, Ontario, Canada. It was unquestionably the biggest bookstore in the world when it first opened in 1980 in a converted bowling alley. The Guinness Book of World Records currently names a Barnes and Noble outlet in New York City as the world's largest bookstore, although World's Biggest still claims the title on the basis that it depends on how "biggest" is defined.

The store was originally owned by Coles, which was bought along with SmithBooks to create Chapters Inc; although it retains its unique name, its stock, distribution and advertising are closely integrated with the Chapters and Indigo chains.

It is noted for its cramped spaces and bright lights, with over 20 kilometres of bookshelves. The store particularly focuses on books about computers, the occult, fiction, and children's literature. The store is located on Edward Street west of Yonge, near the Dundas subway station.
