The Canadian Dollar weakened on Thursday falling to the lowest level in a three-year period after the Bank of Canada Governor Stephen Poloz signaled the central bank may lower benchmark interest rates as the country's inflation eases. The so-called Loonie declined 0.3% to C$1.0684 per U.S. Dollar as of 5 p.m. Toronto time following a drop to the weakest level since 2010 at C$1.0707.
