(Updates at market close)

By Fergal Smith

March 17 (Reuters) - Canada's main stock index rallied

for a second straight day on Monday as some investors took the

view that the recent selloff in the market was a buying

opportunity, with energy and metal mining shares leading

broad-based gains.

The Toronto Stock Exchange's S&P/TSX composite index

ended up 231.71 points, or 0.9%, at 24,785.11,

extending its rebound from a four-and-a-half-month low on

Thursday.

"We got quite oversold," said Stan Wong, portfolio manager

at Scotia Wealth Management. "Not too surprised that we have a

little bit of a reprieve in the markets."

Wall Street also rallied as investors assessed the latest

economic data to gauge the impact of the Trump administration's

policies.

U.S. tariff hikes will drag down growth in Canada, Mexico

and the United States while driving up inflation, the OECD

forecast.

If additional "tariff talk comes out of the U.S. that might

slow us down a little bit but really I see the recent volatility

more as an opportunity rather than as an obstacle," Wong said.

The energy sector rose 1.5% as the price of oil

settled 0.6% higher at $67.58 a barrel.

Supportive of oil, the U.S. vowed to keep attacking Yemen's

Houthis until the Iran-aligned group ends its assaults on

shipping, while Chinese economic data buoyed hopes for higher

demand.

TerraVest Industries Inc ( TRRVF ) shares jumped 20.5% after

the home heating product manufacturer announced the acquisition

of EnTrans International.

The materials sector, which includes fertilizer companies

and metal mining shares, added 1.8%, as gold and copper

prices climbed.

All ten major sectors ended higher, with heavily weighted

financials gaining 1.1%.
