LONDON, July 3 (Reuters Breakingviews) - Canary Wharf may be in trouble once again. While CWG’s average tenancy agreement still has 10 years left, the risk is that itself and the wider Canary Wharf area slip into a vicious circle. Rental incomes on apartments are roughly on a par with offices, per square foot, according to a person familiar with the matter. The 45-storey skyscraper in Canary Wharf has been HSBC's home for more than 20 years. Canary Wharf Group, which runs the east London financial district, declined to comment.
