Hi,
According to Bloomberg news:December 24,2011Canada Dollar Reaches Strongest in Three Weeks on North American Recovery
Canada's dollar had its biggest gain in three weeks as economic reports in the nation and the U.S., its largest trading partner, signaled a recovery may be gaining momentum.
The currency rose against most of its major counterparts, excluding South Africa's rand, as stronger-than-expected data outweighed climbing yields on European sovereign debt. Canada's dollar was buoyed as crude oil, its biggest export, advanced the most in three weeks and stocks rallied to erase their 2011 losses. The nation added jobs in December for the first time in three months, according to a Bloomberg survey.
