The loonie was down 0.02 of a cent at 98.31 cents US.
The price of July copper dipped two cents to US$3.26 a pound, signalling a weakening outlook for China and Europe and leaving the Canadian dollar vulnerable to more declines. The loonie was close to parity with the U.S. greenback just last week.
The June crude contract was up nine cents at US$94.30 a barrel, while June gold bullion fell $28.30 to US$1,396.20 an ounce — its lowest price in a month.
Meanwhile, a report from the C.D. Howe Institute called for incoming Bank of Canada governor Stephen Poloz to consider hiking interest rates.

That's less than the 0.3 per cent rise analysts had been expecting. There were also signs that the French economy has also fallen back into a recession.
