The price of oil, one of Canada's major exports, fell on concern that the spread of a respiratory virus from China could lower fuel demand if it stunts economic growth in an echo of the SARS epidemic nearly 20 years ago. U.S. crude oil futures were down 2.8% at $55.16 a barrel.

On Wednesday, the Bank of Canada left its benchmark interest rate on hold at 1.75% as expected but said a future cut was possible should a recent slowdown in domestic growth persist.

Money markets now see a greater-than 50% chance of a rate cut by April, up from about 20% before the rate decision.

At 9:41 a.m. EST (1441 GMT), the Canadian dollar was trading 0.2% lower at 1.3159 to the greenback, or 75.99 U.S. cents. The currency hit its weakest intraday level since Dec. 23 at 1.3171.

The loonie has fallen 1.3% since the start of the year after climbing 5% in 2019, when it was the top-performing G10 currency.

Canada's retail sales report for November is due on Friday, which could be closely watched by investors after the October data showed the biggest monthly decline in nearly one year.

Canadian government bond prices were higher across the yield curve in sympathy with U.S. Treasuries. The two-year rose 7.6 Canadian cents to yield 1.509% and the 10-year was up 44 Canadian cents to yield 1.402%.

The 10-year yield hit its lowest intraday level since Nov. 20 at 1.402%.
