The Canadian dollar was lower ahead of the ECB announcement and Canadian jobs data which also comes out on Friday, falling 0.52 of a cent at 100.92 cents US.
As expected, The Bank of Canada left its benchmark interest rate unchanged at one per cent while warning that rates will have to rise at some point in the future. The central bank also said that there has been a widespread slowing of activity across most economies.
The loonie seemed unaffected by Tuesday's Quebec election which saw the pro-independence Parti Quebecois win the contest, but only securing a minority government.

Traders anxiously awaited Thursday's interest rate announcement from the European Central Bank amid hopes the ECB will move to ease the eurozone debt crisis by addressing the high borrowing costs that have bedevilled some of the weakest members of the monetary union, particularly Spain. It is expected some sort of bond-buying program will be announced but it would come with strings attached.
To be eligible for the central bank’s help, for example, countries would likely have to formally apply for assistance from the eurozone's rescue facility and accept conditions on their budget policies, which many governments would be reluctant to do.
"The best thing we can hope for is the European Central Bank to get its firepower all lined up and try to cap rates and do that in a way that doesn’t stoke inflation and allows time to pass and finances to get a bit healthier," said Paul Vaillancourt, vice president and chief investment officer at Canadian Wealth Management.
"In times of crisis, sometimes the best you can expect is do no harm."
Investor sentiment improved somewhat as Bloomberg News reported European Central Bank President Mario Draghi’s bond-buying program involves unlimited purchases of government debt.
Europe's economy also remains fundamentally weak. A survey of the eurozone's services sector on Wednesday showed the sector continued to contract in August.

Markets also looked ahead to Friday's release of the August non-farm payrolls report to see if a weak report would persuade the U.S. Federal Reserve to embark on another round of stimulus.

Michael Walkley said in a research report that he expects RIM to release its BlackBerry 10 smartphone as scheduled in the first quarter of next year. But he says that RIM has lost too much smartphone market share to Apple and Android and will mightily struggle to win back consumers even if BlackBerry 10 smartphones are very competitive and compelling products.
