The Bank of Canada, which hiked interest rates three times in 2018 to leave its benchmark rate at 1.75 per cent, is expected to refrain from tightening further on Wednesday after it worried last month that a sharp drop in oil prices since October could hurt Canada’s economy.

At 4:34 p.m. (2134 GMT), the Canadian dollar was trading 0.2 per cent higher at 1.3276 to the greenback, or 75.32 U.S. cents. The currency touched its strongest intraday level since Dec. 7 at 1.3268.
