TORONTO, Oct 27 (Reuters) - Canada's main stock index hit a record high on Friday as overall higher energy stocks offset a batch of quarterly results that largely fell short of expectations.
Canadian diary producer Saputo Inc provided one of the biggest boosts, rising 4.7 percent to C$47.03. It became Australia's top milk producer by agreeing to pay up to $490 million for Murray Goulburn Co-operative, its second major acquisition in the country.
The broader consumer staples group climbed 0.5 percent
The energy group accounted for the bulk of the gains, climbing 0.9 percent, helped by stronger oil. U.S. crude prices were up 1.5 percent to $53.41 a barrel. Encana Corp advanced 3.1 percent to C$14.18.
Cameco Corp was an exception in the sector, tumbling 10.5 percent to C$10.17 after the uranium producer posted a surprised third-quarter loss and cut its full-year production outlook.
At 11:27 a.m. ET (1527 GMT), the Toronto Stock Exchange's S&P/TSX composite index marched toward its seventh straight week of gains, rising 57.74 points, or 0.36 percent, to a record high of 15,949.37.

First Quantum Minerals Ltd stumbled 3.6 percent to C$13.96 after it posted a quarterly loss. Teck Resources Ltd shares extended losses, falling 2.5 percent to C$26.15 after analysts cut their target price following its results.
Winpak Ltd, which manufactures and distributes packaging materials and machines, plunged 10.2 percent to C$48.51 after third-quarter results fell short of forecasts.
