Nov 30 (Reuters) - Canada's main stock index rose on Thursday and posted its biggest monthly advance in three years, as the heavily weighted financials sector gained on upbeat earnings.

The Toronto Stock Exchange's S&P/TSX composite index ended up 120.09 points, or 0.6 percent, to 20,236.29. For the month, it was up 7.2%, its biggest monthly advance since November 2020.

Financials, which account for 29% of the Toronto market's weighting, added 1.2% as Royal Bank of Canada and the Canadian Imperial Bank of Commerce advanced 3.2% and 5.1% respectively, after beating quarterly profit estimates.

The industrials sector was another standout, adding 1.1%. Energy was up 0.1% even as U.S. crude oil futures settled 2.4% lower at $75.96 a barrel.

Oil fell after OPEC+ producers agreed to voluntary oil output cuts for the first quarter next year that fell short of market expectations.

Technology shares gave back some recent gains, falling 0.8%.

Powersports vehicle maker BRP was also a drag, slumping 11.8% after the company trimmed its full-year adjusted profit forecast. (Reporting by Fergal Smith in Toronto and Shashwat Chauhan in Bengaluru; Editing by Tasim Zahid)
