* Canadian dollar at C$1.3355, or 74.88 U.S. cents
* Bond prices lower across the yield curve
TORONTO, Oct 26 (Reuters) - The Canadian dollar weakened slightly against its U.S. counterpart on Wednesday, pressured by lower oil prices amid doubts that major producers will agree to output cuts.
Oil fell for a third straight day as investors grew increasingly doubtful that members of the Organization of the Petroleum Exporting Countries will agree to cut output and as U.S. inventories staged a surprisingly large increase. U.S. crude CLc1 prices were down 1.62 percent at $49.15 a barrel. O/R
Oil is one of Canada's major exports.
The loonie has been weakening since the Bank of Canada acknowledged last week that it had considered cutting interest rates at its policy meeting.
On Monday, it touched its weakest in seven months at C$1.3398.
Still, the implied probability of an interest rate cut by mid-2017 has dipped to less than 30 percent since Bank of Canada Governor Stephen Poloz told lawmakers on Monday it was not clear cut that the central bank should try to speed up closure of the output gap, the economy's spare capacity, by cutting rates, as it would leave the bank very close to using unconventional tools.
The probability was more than 40 percent after weaker-than-expected domestic retail sales and inflation data on Friday. BOCWATCH

A planned EU-Canada summit to sign a free trade deal was still possible on Thursday, European Council President Donald Tusk said, as Belgian politicians entered a second day of talks on the future of the pact. government bond prices were lower across the yield curve in sympathy with U.S. Treasuries. The two-year CA2YT=RR fell 1.5 Canadian cents to yield 0.550 percent. The benchmark 10-year CA10YT=RR declined 15 Canadian cents to yield 1.155 percent.
The 10-year yield fell 0.9 of a basis point further below its U.S. equivalent to leave a spread of -62.8 basis points, its widest gap since March 29, indicating underperformance for U.S. Treasuries.
