The Canadian currency rate went down against U.S. dollar as the winter Business Outlook Survey, released by Bank of Canada Monday, provided some positive signs for Canadian economic outlook, notably for exports and investment, but the bank also said firms remain concerned about weak demand and domestic uncertainty, and sales expectations were supported by improvements in the United States. The Canadian dollar closed down at 0.9134 U.S. dollar Tuesday, compared with 0.9209 U.S. dollar in Monday's trading.
