The Competition Bureau has asked Indigo Books and Music Inc. to hand over documents as part of its ongoing investigation into alleged anti-competitive ebook pricing practices. The watchdog said Tuesday it filed an application in Federal Court last week seeking "certain records" from Canada's largest bookstore chain and Kobo Inc., which is owned by Japanese ecommerce firm Rakuten Inc. Greg Scott, a spokesman for the bureau, says the request was just for documents and does not mean that Indigo or Kobo are the subject of the investigation.
