TORONTO, April 22 (Reuters) - Canada's main stock index

on Wednesday clawed back some of the previous day's steep

decline as resource shares rose and investors cheered an

extended ceasefire in the Middle East.

The Toronto Stock Exchange's S&P/TSX Composite Index

ended up 146.81 points, or 0.4%, at 33,955.11. On

Tuesday, the index posted its biggest drop in a month, falling

1.6%.

Iran seized two ships in the Strait of Hormuz, tightening its

grip on the strategic waterway after U.S. President Donald

Trump called off attacks with no sign of peace talks restarting.

"As long as this on-again and off-again war continues,

market volatility is going to be high," said Michael Sprung,

president at Sprung Investment Management.

"The day to day machinations of the market are revolving

somewhat around the Strait of Hormuz and energy prices. I think

beyond that the implications of inflation and possibly

stagflation are beginning to settle into people's

consciousness."

The halting of traffic in the strait has led to an oil price

shock, boosting inflation. Data on Monday showed that Canada's

annual inflation rate rose to 2.4% in March, from 1.8% in

February.

U.S. crude oil futures settled 3.8% higher at $92.96

a barrel, which helped lift the energy sector by 1.3%.

The U.S. Supreme Court rejected Enbridge's ( ENB ) bid to

change the venue of an environmental lawsuit by Michigan seeking

to force the Canadian energy company to stop operating an oil

pipeline between two of the Great Lakes. Shares of Enbridge ( ENB ) were

down 0.2%.

The materials group added 1.4% as gold and

copper prices rose.

Rogers Communications ( RCIAF ) shares jumped 13.5% as the

telecom company reported quarterly revenue slightly above

analysts' average estimate and forecast 2026 capital expenditure

about 30% below 2025 levels.

Consumer staples was one of five major sectors to

post declines. It lost 0.9%, with shares of Metro down

2.7% after the grocery retailer said the Laval labor dispute

will have an impact on the company's third-quarter results.
