TORONTO, May 5 (Reuters) - Canada's main stock index rose over 1 percent on Friday, as a rebound in oil prices drove energy stocks higher and major lenders posted robust gains.
The most influential movers on the index included Bank of Nova Scotia, which rose 2.2 percent to C$76.82, and Tourmaline Oil, which added 5.9 percent to C$27.59 after the energy company reported strong quarterly earnings on Thursday.
The overall financials group, which accounts for more than a third of the weight of the index, gained 1.0 percent.
Home Capital Group, Canada's biggest non-bank mortgage lender, climbed 4.0 percent to C$6.25 after it announced that Alan Hibbens would replace co-founder Gerald Soloway on its board.
Soloway had been accused by regulators of making "materially misleading statements" to investors, and on Thursday its shares slumped more than 12 percent on a regulatory hearing to investigate the matter.
The oil and gas companies' sector rose 2.3 percent.
Suncor Energy Inc ticked up 1.7 percent to C$42.47, while TransCanada Corp, which reported better-than-expected first-quarter results, rose 1.5 percent to C$63.60. Encana Corp added 3.0 percent to C$14.75.
Oil prices, which tumbled on Thursday due to oversupply fears, recouped some of the losses. U.S. crude prices were up 1.9 percent to $46.40 a barrel, while Brent crude also added 1.9 percent to $49.29.
At 11:24 a.m. ET (1524 GMT), the Toronto Stock Exchange's S&P/TSX composite index rose 171.51 points, or 1.11 percent, to 15,568.21.
Of the index's 10 main groups, healthcare was the lone decliner, sliding by just under 0.5 percent.
Air Canada, which reported a narrower-than-expected loss on Friday, saw its shares rise 6.1 percent to C$13.57. The industrials group rose 0.4 percent.
Materials stocks like miners and other resources added 1.5 percent.
Advancing issues outnumbered declining ones on the TSX by 195 to 50, for a 3.90-to-1 ratio on the upside. (Reporting by Solarina Ho Editing by W Simon)
