However, Hostess' move will not affect the production of Wonder Bread in Canada, where Weston Bakeries is the licensed trademark holder and bakes the bread with "100 per cent Canadian wheat."
Weston "has no relationship with Hostess Brands' Wonder bread, so Canadians can rest assured that freshly-baked Canadian Wonder bread will continue to be available in stores nationwide," the Toronto company said in a separate release.
Weston uses the Wonder brand in Canada on white and whole wheat bread as well as on hamburger and hot dog rolls and English muffins.
Hostess Brands' move also won't affect the otherwise-limited use of the Hostess brand in Canada.
Montreal dairy giant Saputo has owned the Hostess brand in Canada since 1999 when it bought parts of food processor Culinar Inc., which in turn had bought the brand's Canadian use in 1993.
The Financial Post reported Friday that Weston would not seek to buy any of Hostess Brands' U.S. assets, and that Saputo declined comment on the same question. Saputo, the Post noted, has not marketed goods such as Twinkies among its Hostess-branded fare in Canada.
