The lack of details on economic policy by U.S. President-elect Donald Trump at his news conference on Wednesday - the first since the November election - weighed on investor optimism.

"I just think that people traded quickly into their belief of new policy on Trump coming into office and that pulls forward a lot of returns," said Ben Jang, portfolio manager at Nicola Wealth Management.

The Toronto Stock Exchange's S&P/TSX composite index <.GSPTSE> has rallied more than 5 percent since the Nov. 8 election. Last week it touched its highest level since September 2014, at 15,621.40, just shy of its record high.

"I think the sell-off is helping the market to normalize a bit and better understand that you need to wait until we are into the 100-day mark (of the new presidency) and we start to see a resemblance of what reform is going to look like," Jang said.

The TSX closed down 73.38 points, or 0.47 percent, at 15,418.16.
