TORONTO, May 17 (Reuters) - The Canadian dollar edged lower against its U.S. counterpart on Thursday, pulling back from a near one-week high as investors turned attention to domestic inflation and retail sales data due on Friday.
At 4 p.m. EDT (2000 GMT), the Canadian dollar CAD=D4 was trading 0.1 percent lower at C$1.2798 to the greenback, or 78.14 U.S. cents. The currency touched its strongest since May 11 at C$1.2749.
"We haven't done anything too significant here," said Amo Sahota, director at Klarity FX in San Francisco. "We're getting ready for tomorrow morning's main event."
Canada's inflation report for April and March retail sales data could help guide expectations for further interest rate hikes from the Bank of Canada. The central bank has raised its benchmark rate three times since July to leave it at 1.25 percent.
"They are two very important numbers for Canada," Sahota said.
On Wednesday, Bank of Canada Deputy Governor Lawrence Schembri said uncertainty about the North American Free Trade Agreement (NAFTA) renegotiations is one of the reasons the central bank has kept interest rates low. Prime Minister Justin Trudeau said on Thursday he felt "positive" about talks to rework NAFTA, while a top Mexican official held out hope a deal could be hammered out by the end of May. officials say the negotiations need to wrap up very soon to give the current Congress time to vote on a final text for a revamped trade pact.
