The loonie was ahead 0.09 of a U.S. cent to 79.39 cents after Canada Mortgage and Housing Corp. said that housing starts during February came in at an annualized rate of 156,276 units, down from 187,025 units in January.
Economists had expected a reading of around 179,000, but analysts pointed out that severe winter weather during the month likely played a role.
In addition, February isn't generally an important time for home building, which is a further reason to downplay this particular month's figures, said CIBC World Markets chief economist Avery Shenfeld.
"Still, we see real residential construction as a slight negative in terms of its contribution to real GDP growth in upcoming quarters," Shenfeld said.
Traders also looked ahead to the release of February employment data on Friday. Statistics Canada is expected to report that about 5,000 jobs were lost during the month following a gain of 35,400 jobs in January.
On the commodity markets, a weaker U.S. dollar helped April crude in New York was 39 cents higher to US$50 a barrel.
April bullion gained $2.20 to US$1,166.50 an ounce while May copper rose six cents to US$2.67 a pound.
