In Canada, there are no laws regulating SIM locking or unlocking. No Canadian wireless service provider sells unlocked phones, and none unlock after service contracts expire. Though you can buy unlock codes from Bell mobility for a cost now. Changes to the Copyright Act proposed by the Canadian government would make any circumvention of digital locks, such as carrier locks on cell phones, illegal. In 2008, then-Industry Minister Jim Prentice introduced Bill C-61 to update the Copyright Act and implement World Intellectual Property Organization (WIPO) treaty provisions. However, the bill expired with the dissolution of parliament for the 2008 federal election. The government still maintains interest in these reforms, as witnessed by the public consultations held during summer 2009 and by its current participation in Anti-Counterfeiting Trade Agreement(ACTA) negotiations.
