The S&P/TSX composite index gained 17.7 points to 13,614.63 with lift coming primarily from miners and techs.
The Canadian dollar continued to plumb multi-year depths, down 0.27 of a cent to 92.56 cents US, its lowest close since late October 2009.
New York markets were mainly lower following the release of the minutes from the meeting last month when the Fed decided to start tapering its US$85 billion a month of bond purchases by $10 billion starting this month and said further decreases would depend on economic data.
But traders had hoped there would be some clues as to the pace of further tapering and now the focus has shifted to Friday and the release of the government's employment report for December.
Expectations for a stronger than expected jobs report on Friday grew after payroll firm ADP reported Wednesday that the U.S. private sector created 238,000 jobs in December.
The ADP data came out two days before the U.S. government releases its non-farm payrolls report and expectations have been that the U.S. economy cranked out about 195,000 jobs in December.
The Dow Jones industrials lost 68.2 points to 16,462.74, the Nasdaq added 12.43 points to 4,165.61 and the S&P 500 index declined 0.39 of a point to 1,837.49.
Meanwhile, the Fed minutes did nothing to dispel concerns that the U.S. central bank will exit its latest quantitative easing program well before the end of 2014.
"(Tapering) is going to be data dependent but I think there's a school of thought now that we will start to see that tapering of $10 billion, maybe $15 billion a month," said Garey Aitken, chief investment officer at Franklin Bissett Investment Management.
"So they're not just going to go from $85 (billion) to $75 (billion) and leave it there — this is going to be a methodical wind-down of this so that by the third quarter we have completely stopped (the asset purchases)."
The bond purchases have kept long-term rates low and encouraged investors to put their money in the stock market.
TSX gains were paced by the base metals segment, up 0.74 per cent even as the March copper contract lost early gains and gave back two cents to US$3.34 a pound. Performance was mixed with HudBay Minerals (TSX:HBM) ahead 20 cents to C$8.81 while Teck Resources (TCK.B) declined 33 cents to $26.28.

Financials were also supportive with Manulife Financial ahead 50 cents to $21.35.
The gold sector was the biggest drag, down about one per cent as the February gold bullion contract slipped $4.10 to US$1,225.50 an ounce. Barrick Gold (TSX:ABX) faded 30 cents to C$19.37 while Goldcorp (TSX:G) fell 25 cents to $23.87. The component was the worst performer on the TSX last year, losing almost 50 per cent, but it has been generally positive so far this year, up almost four per cent over the last week.
Industrials also dragged, with Canadian National Railway (TSX:CNR) down 95 cents to $58.63. A CN train carrying liquefied petroleum gas and crude oil derailed in northwestern New Brunswick on Tuesday.
