TORONTO (Bloomberg) - Canadian stocks rose for the first time in three days, sending the main index to its biggest gain this year as energy producers rallied along with oil prices and finance companies rebounded from a five-year low.

Suncor Energy Inc. surged 11 percent, the most in six weeks. Research In Motion Ltd. rose to the highest since October on speculation smartphone makers will weather a slump in cellphone sales better than other handset producers.

Royal Bank of Canada paced the rally in finance after saying that it will raise C$200 million in preferred shares to bolster capital.

The Standard & Poor's/TSX Composite Index rose three percent to 8,757.89 in Toronto. Canada's main equity benchmark slid 3.8 percent yesterday as Suncor posted a loss and slashed oilsands spending plans, and investors speculated global financial institutions will need more government aid to avoid failures.

"We're positioned for serious snapback in oil prices as production capacity is taken down," said Greg Taylor, who helps manage about $1.6 billion as a portfolio manager with Aurion Capital in Toronto.

"RIM has acted quite well - they're gaining market share as a smartphone maker."

Suncor added C$2.48 to C$24.58. The second-largest oilsands producer rallied after analysts today cut their share price targets to as low as C$30 and maintained their recommendations that investors buy the stock. Justin Bouchard at Raymond James & Associates cut Suncor to "outperform" from "strong buy" and lowered his share target by 18 percent to C$41. That implies a gain of 86 percent from Tuesday's close.
