Kanitz v Rogers Cable Inc, [2002] O.J. No. 665 is a leading Canadian decision on website service contracts. The court held that a posting on a corporate website is sufficient notice to bind customers to changes in their user licenses. A number of Rogers Cable customers started a class action to challenge Rogers amending of the arbitration provision in their user agreement. They claimed that customers were not given sufficient notice of the amendments to make it valid. Rogers should have emailed all its customers to properly notify them.
