(Updates at market close) By Anand Gopal R and Fergal Smith TORONTO, Nov 2 (Reuters) - Canada's main stock index rallied on Monday as a sharp drop in oil prices boosted investor sentiment at the start of a new month, with industrial and metal mining shares leading broad-based gains. The S&P/TSX Composite Index ended up 181.06 points, or 0.5%, at 35,801.09, recouping some of Friday's steep decline.
