The S&P/TSX composite index fell 75.7 points to 14,537.62.
The Canadian dollar tumbled 0.67 of a cent to 88.05 cents US., with the decline accelerating as Bank of Canada governor Stephen Poloz said in a speech that the downturn that followed the 2008 financial crisis "was deep and has proved to be long lasting."

"I would expect that to continue to be the case for a while. There are still a lot of issues that have to be worked out in Europe and China in terms of the direction and the pace of economic growth in the near to medium term."
