The currency rose 0.19 of a cent to 97.14 cents US as Statistics Canada said the trade deficit with the world narrowed to $237 million in January from $332 million in December.
Exports rose 2.1 per cent to $39.1 billion while imports decreased 1.9 per cent to $39.3 billion.
Meanwhile, the U.S. trade deficit widened in January, reflecting a big jump in oil imports and a drop in exports.
The U.S. Commerce Department says the deficit rose to US$44.4 billion, an increase of 16.5 per cent from December. U.S. exports dropped 1.2 per cent to $184.5 billion while imports rose 1.8 per cent to $228.9 billion as oil imports surged 12.3 per cent.
Even with the wider U.S. trade deficit in January, economists say they think it will narrow slightly this year, in part because of continued gains in U.S. energy exports.
Commodity prices were higher with the April crude contract on the New York Mercantile Exchange up $1.13 to US$91.56 a barrel.
