Bank of Canada Deputy Governor Tim Lane repeated on Wednesday the central bank's message that interest rate increases will likely be needed, but only over time. 

The "over time" phrase was introduced in the bank's key guidance in its rate statement on October 23 as a way of signaling that while the next rate move is likely to be up, such a move was less imminent than it had been.

"Over time, some gradual withdrawal of monetary policy stimulus will likely be required, consistent with achieving the inflation-control target," Lane said, according to a prepared presentation he was giving on Wednesday in Moncton, New Brunswick.
