FILE - This March 9, 2008 file photo shows a cross-country skier along the Bruce Trail on the Niagara Escarpment in Milton, west of Toronto. The Bruce Trail is the oldest and longest marked hiking trail in Canada at 521 miles (840 kilometers) long and over 273 miles (440 kilometers) of side trails, many of which are in Ontario. While autumn turns the trails into blazing streams of fiery reds, pumpkin orange and honeyed hues, the winter snow makes it perfect for cross-country skiing and snow-shoeing.
