The loonie had been lower for most of the session while the greenback advanced amid another round of worry connected with elections in Greece later this month.
The U.S. currency strengthened and the euro fell to the lowest level since March 2006, with new doubts raised about whether Greece will exit the eurozone following elections later this month.
Traders are weighing the outcome of the Greek elections that might be won by the anti-austerity Syriza party. Such a victory would raise doubts about whether the country will stick to the terms of its international bailout and stay in the euro bloc. Germany has warned Greece against reneging on the bailout conditions should Syriza win this month's general election.
Jitters about Greece helped push the euro down as low as US$1.1864 earlier Monday morning.
On the U.S. economic calendar for this week, investors will digest U.S. November factory orders data, purchasing managers data for last month covering the manufacturing and service sectors and the release of the minutes from last month's Federal Reserve meeting for indications of when the central bank might move to hike interest rates.
Markets will also digest Canadian data including merchandise trade, housing starts and building permits.
But it is the latest readings on employment that will focus markets.
