TORONTO, Oct 26 (Reuters) - The Canadian dollar weakened on Wednesday against its U.S. counterpart, pressured by lower oil prices and lingering risk that the Bank of Canada will cut interest rates further.
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 against the greenback in seven months at C$1.3398.
"There is most definitely a potential for additional monetary easing in Canada," said Brad Schruder, director of corporate sales and structuring at BMO Capital Markets.
The Canadian central bank's last rate cut came in July 2015, when it trimmed by 25 basis points to leave its policy rate at 0.50 percent.
"The decision by the federal government to impose new restrictions essentially around mortgage finance has given the Bank of Canada some breathing space that it did not have before," Schruder added.
Recent new measures for Canada's housing market have come amid worries about a potential bubble.
There is strong evidence that many of Canada's housing markets are overvalued, the federal housing agency said on Wednesday, but it tempered the warning with a forecast projecting cooler housing starts, sales and prices in 2017 and 2018. crude CLc1 prices settled 78 cents lower at $49.18 a barrel even after a surprise drawdown in U.S. crude inventories, as traders remained cautious that OPEC would be able to cut production come late November.

Oil is one of Canada's major exports.
The Canadian dollar CAD=D4 ended at C$1.3382 per U.S. dollar, or 74.73 U.S. cents, weaker than Tuesday's close of C$1.3352, or 74.90 U.S. cents.
The currency's strongest level of the session was C$1.3314, while its weakest was C$1.3385.
Belgian politicians struggled to agree additions to a planned EU-Canada free trade agreement and keep alive a deal backed by all 27 other EU governments, but rejected by the French-speaking south of Belgium. looming failure of free trade talks with the European Union would derail Canada's push to reduce its economic dependence on the United States. government bond prices were lower across the yield curve in sympathy with U.S. Treasuries. The two-year CA2YT=RR fell 3 Canadian cents to yield 0.558 percent and the benchmark 10-year CA10YT=RR declined 14 Canadian cents to yield 1.154 percent.
The 10-year yield narrowed 1.8 basis points further below its U.S. equivalent to leave a spread of -63.7 basis points, its widest gap since March, indicating underperformance for U.S. Treasury debt.
