TORONTO (Bloomberg) - Canadian stocks rose to a five-month high, led by raw material producers, after Potash Corp. of Saskatchewan Inc. raised prices and gold futures climbed.

Potash advanced for a 12th day, the longest stretch of gains since its initial public offering in 1989. The world's largest fertiliser maker boosted the price of crop nutrient potash by threefold amid soaring food demand. Barrick Gold Corp. and Kinross Gold Corp. led bullion producers as gold prices rose to a two-week high.

"We're seeing a resurgence in commodity stocks of all types - material, energy and agriculture products," said Laura Wallace, who helps oversee about $300 million as managing director at Coleford Investment Management Ltd. in Toronto. "There's still a belief that there will be a big demand for fertilizers as the demand for food and agricultural products increases."

The Standard & Poor's/TSX Composite Index gained 1.8 percent to 14,099.48, the highest since November 8. The Canadian stock benchmark has posted declines in only two trading sessions this month.

Raw-material stocks, which make up one-fifth of the S&P/TSX, have gained 20 percent this year on climbing commodity prices. Oil futures reached as high as $115.07 a barrel today after the US government said crude oil supplies dropped.

Economic reports from China drove speculation that metal producers will not be able to keep up with demand, pushing copper futures higher.

Potash had the biggest gain since March 11, rising 6.1 percent to a record C$199.59.

Prices for potash and other agricultural nutrients have soared as farmers seek to boost yields to meet demand for crops used for food, fuel and animal consumption.

Agrium Inc., North America's third-largest producer, added 7.7 percent to C$86.70. The S&P/TSX Materials Index rose the most since March 25, climbing four percent.

Barrick, the world's largest gold producer, rose 3.9 percent to C$46.12. Kinross, Canada's third-biggest gold mining company, increased 5.4 percent to C$25.48.

Gold futures for June delivery gained 1.7 percent to $948.30 an ounce in New York.
