TORONTO (Reuters) - Canada's main stock index ended slightly lower on Monday, breaking a six-day rally, as railway stocks weighed and an early jump in energy stocks lost steam.
The Toronto Stock Exchange's S&P/TSX composite index has gained some 800 points since mid-November as prices for crude oil, a major Canadian export, have jumped.
