TORONTO (Reuters) - Canada's main stock index rose on Monday as a jump in Valeant Pharmaceuticals International Inc (>> Valeant Pharmaceuticals Intl Inc) helped offset weakness in the energy sector after the price of Brent crude oil dropped.

Valeant shares jumped 3.5 percent to C$254.95 after recent acquisition moves, helping to fuel an advance in the index's healthcare sector.

Trading in the benchmark TSX index has been choppy in recent months because of fluctuations in the price of oil. It is up about 4 percent since the start of the year.

"Oil has been bouncing around a lot. That seems to be impacting the energy group, but not so much the rest of the index," said Elvis Picardo, strategist and vice president of research at Global Securities in Vancouver.

"There's so much uncertainty surrounding the Canadian market, whether it's the housing sector or the impact crude oil will have on the economy," he added.

The Toronto Stock Exchange's S&P/TSX composite index <.GSPTSE> closed up 29.71 points, or 0.2 percent, at 15,264.05. Six of the 10 main sectors on the index were higher.

The gold-mining sector fell with the bullion price. Goldcorp Inc (>> Goldcorp Inc.) shed 3.4 percent to C$26.59, and Barrick Gold Corp (>> Barrick Gold Corp.) was down 1.5 percent to C$16.01.
