BMO and Bank of Nova Scotia are due to report earnings on Tuesday, kick-starting Canada's bank earnings season. "There's still some nervousness with the banks. Some of the [analyst] previews were a little more cautious on commercial real estate," said Greg Taylor, portfolio manager at Purpose Investments. The materials sector declined 1.2 per cent as gold and copper prices fell. Energy was up 0.5 per cent as oil settled 1.4 per cent higher at $77.58 (U.S.) a barrel on possible shipping disruptions.
