Suncor Energy fell 3.83 percent to C$34.87. Toronto also followed world stocks lower as several US economic reports fuelled doubts about a quick economic recovery, while Standard & Poor's revised its UK ratings outlook lower, stoking concern that Washington's growing deficit could lead to a credit rating downgrade for the United States. The glum news came a day after the US Federal Reserve, in minutes released from its April policy meeting, cut its outlook for economic growth over the next three years and said a full recovery could take five or six years. Financials fell 3.1 percent. Manulife Financial retreated 4.6 percent to C$21.39.
