TORONTO, April 28 (Reuters) - Canada's main stock index rose on Thursday as resource stocks rose and Bombardier Inc rallied after winning a large plane order, while the financials group retreated.
Some of the most influential movers on the index included gold stocks. Barrick Gold Corp rose 3.8 percent to C$21.78, while Goldcorp Inc was up 4.2 percent at C$23.54 after reporting on Wednesday better-than-expected earnings.
Spot gold rose 0.8 percent as the Bank of Japan held off from expanding monetary stimulus, boosting the yen versus the dollar, and after the Federal Reserve signaled on Wednesday that it was in no rush to tighten monetary policy.
The overall materials group, which includes precious and base metals miners and fertilizer companies, added 2.2 percent.
Energy stocks rose 0.9 percent as oil prices set new 2016 highs. Suncor Energy Inc advanced 1.8 percent to C$36.91, while U.S. crude prices were up 0.3 percent to $45.47 a barrel.
Bombardier Inc rose 3.5 percent to C$2.08, having touched its highest since July 8 last year of C$2.28.

Valeant Pharmaceuticals International Inc rose 2.4 percent to C$45.16. Activist investor William Ackman promised U.S. lawmakers on Wednesday he will urge the company's board to reduce the high prices of four life-saving drugs now at the heart of two congressional probes.
