The loonie moved up 0.22 of a cent to 91.3 cents US.
The U.S. Commerce Department reported that retail sales for March were up 1.1 per cent from February, higher than the 0.9 per cent rise that economists had forecast.
The government also revised February to a 0.7 per cent gain, more than double its previous estimate. Sales had fallen in January and December amid severe winter weather.
The data was well received as it also pointed to stronger economic growth for Canada's largest trading partner.
"Although earlier weather-related weakness suggests consumer spending slowed to around three per cent in the first quarter after the best performance in three years in the fourth quarter, the sharp rebound in March retail sales suggests a complete recovery in Q2, with spending growth close to 3.5 per cent annualized," said BMO Capital Markets senior economist Sal Guatieri.
"This, in turn, should anchor a solid rebound in GDP growth to 3.3 per cent in Q2 from an estimated 1.2 per cent in Q1."
Traders are also focused on the Bank of Canada and the central bank's next interest rate announcement on Wednesday. Analysts universally expect the bank to leave its key rate at one per cent, where it has been since September 2010.
And generally, the announcement isn't expected to have much effect on the currency.
"We expect USD/CAD to be relatively comfortable either side of $1.10 (90.9 cents US) for the next several months, with a shift lower only to come if governor Poloz shifts his tone to a less dovish one," said Camilla Sutton, chief FX strategist at Scotiabank Global Banking and Markets.
"However, the stronger the Canadian dollar is, the more likely governor Poloz will be to maintain his dovish tone, even as the (Bank of Canada) officially holds a neutral tone."
The other major Canadian economic item for this week is the latest read on inflation.
Economists expect that the consumer price index climbed 0.4 per cent in March. They also expect a positive read from the February manufacturing shipments report, which comes out on Tuesday.
Commodity prices were mixed, with May crude on the New York Mercantile Exchange up 31 cents to a six-week high of US$104.05 a barrel.
May copper was up one cent at $3.05 a pound while June gold bullion gained $8.50 to US$1,327.50 an ounce.
