* Canadian dollar at C$1.2575 or 79.52 U.S. cents
* Bond prices mostly lower across the maturity curve
TORONTO, Aug 21 (Reuters) - The Canadian dollar was marginally firmer against its U.S. counterpart on Monday as investors look toward comments from central bank officials at the annual Jackson Hole summit and domestic retail sales data later this week.
The world's top central bankers will be gathering at the annual central banking conference and markets will be closely watching for any signals on monetary policy direction.
Last week, the currency touched a two-week high against a U.S. dollar weighed by political uncertainty, after Canadian data showed an uptick in the rate of underlying inflation and oil prices jumped.
At 9:35 a.m. ET (1335 GMT), the Canadian dollar CAD=D4 was trading at C$1.2575 to the greenback, or 79.52 U.S. cents, up 0.1 percent.
The currency was trading between C$1.2567 and C$1.2608.
The loonie's modest gains come even as U.S. crude CLc1 prices slipped 0.47 percent to $48.28 a barrel, as the late rally last week prompted investors to close positions at a higher price. data showed wholesale trade slipping by 0.5 percent in June following eight consecutive monthly increases, greater than the 0.2 percent forecast by analysts. sales figures for June due on Tuesday will be the week's main data highlight, with a Reuters poll forecasting a modest 0.3 percent rise, but flat when autos sales are excluded.
Longer term Canadian government bond prices were lower across the maturity curve, with the two-year CA2YT=RR price flat to yield 1.244 percent and the benchmark 10-year CA10YT=RR rising 3 Canadian cents to yield 1.867 percent.
