TORONTO, Nov 30 (Reuters) - Canada's main stock index had its biggest one-day gain in more than two months on Thursday, boosted by rising energy stocks after OPEC members extended a production cut deal and a rise in Canadian Imperial Bank of Commerce CM.TO after its earnings.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE unofficially closed up 99.76 points, or 0.62 percent, at 16,067.48. Seven of its 10 main sectors ended higher, with the energy group up 2.2 percent.
