Canada’s largest bank, Royal Bank of Canada is placed under review alongside other large banks by Moody’s.  The full report “Challenges for Firms with Global Capital Markets Operations” is a paid for report so I can only speculate that inclusion of RBC is related to its size and degree of inter-bank transactions, holdings and debts.
