 The Canary Wharf Group agreed to pay £500m over 24 years towards the £3.5bn cost of the Jubilee Line extension.The payment was reduced by at least £25m because the line was unable to run at the capacity agreed, mostly due to the collapse of Metronet.The links between Canary Wharf Group and Transport for London remain strong, with Canary Wharf's Finance Director Peter Anderson on the board of TfL and chairing its finance and policy committee.
