TORONTO, May 1 (Reuters) - The Canadian dollar weakened on Monday against its U.S. counterpart as oil prices fell and investors braced for an interest rate decision midweek from the U.S. Federal Reserve.

"There is a political premium priced into the loonie at this point due to NAFTA," Rai said.
Last week, the loonie fell 1.1 percent. It touched on Friday its weakest since February 2016 at C$1.3697.
U.S. crude oil futures settled 49 cents lower on Monday at $48.84 a barrel, pressured by worries that Organization of the Petroleum Exporting Countries-led production cuts may not significantly tighten an oversupplied market in the short term. is one of Canada's major exports.
Canadian government bond prices were mixed, with the curve steepening in sympathy with U.S. Treasuries after U.S. Treasury Secretary Steven Mnuchin said the government is looking into the issuance of ultra long-term bonds.
The two-year CA2YT=RR price rose 0.5 Canadian cent to yield 0.72 percent but the 10-year CA10YT=RR fell 25 Canadian cents to yield 1.577 percent.
