June 17 (Bloomberg) -- Canadian stocks rose, sending the main stock index to a record, led by Potash Corp. of Saskatchewan Inc. and other commodity producers, as corn traded near its high.

Suncor Energy Inc. climbed on an analyst upgrade, pacing gains among energy companies even as crude oil prices retreated. Research In Motion Ltd. extended a record to a third day.

``Canada is in an unbelievably sweet spot now,'' said Rick Hutcheon, who manages about $140 million as chief investment officer at RKH Financial in Toronto. ``The commodity complex is where you want to be the next few years.''

The Standard & Poor's/TSX Composite Index rose 1 percent to 15,089.50 as of 11:12 a.m. in Toronto, surpassing its record close of 15,047.34 on May 20. Canada's stock benchmark is up 9.1 percent this year as oil, grain and metals prices climbed to all-time highs.

Potash Corp., the largest maker of crop nutrients, advanced 2.3 percent to C$241, extending a record to a fifth day.

Suncor added 1.5 percent to C$65.34. The world's second- largest oil-sands miner received an ``outperform'' rating as RBC Capital Markets resumed coverage.

Research in Motion, the maker of the Blackberry e-mail phone, gained 2.2 percent to C$147.40.

Gains in the market were limited as Centerra Gold Inc. tumbled the most in almost two years after Reuters reported that the company's mining permits in the Kyrgyz Republic were canceled. Centerra fell 18 percent to C$5.30.
