The country's largest food processor and distributor said its fresh bakery subsidiary, Weston Foods, bought the manufacturer of artisan and European-style breads to expand its family of bakery brands.

Shares of George Weston, the maker of Wonder bread and Girl Scout cookies, finished down C$1.63, or 2 per cent, at C$80.32 on the Toronto Stock Exchange on Monday.

Weston, which has a cash balance of about C$3.5 billion, bought U.S. manufacturer Keystone Bakeries at the end of August for $185 million.
