Wonder Bread is manufactured in Canada by Weston Bakeries.
This is not a license, since Weston owns the Wonder trademark in Canada, though the packaging is very similar to that used in the United States.

Wonder Bread began appearing on Canadian grocery shelves and home delivery routes as early as 1927.
A product of Northern Bakeries Limited, the bread apparently made its debut in Montreal.
 In 1928, Northern Bakeries Limited registered the "Wonder" trademark with the Canadian Intellectual Property Office.
 Two years later, Wonder arrived in Toronto, baked by Nasmiths Limited.
 Newspaper ads proclaimed "Great news for the people of Toronto – it's here at last – the delicious Wonder Bread."
  Made from unbleached flour and "Slo-Baked," Wonder was said to produce "more slices and thinner slices" when cut, yet would not crumble.
 By 1934, "Sliced Wonder," an early version of sliced bread, was being promoted by the Ideal Bread Company Limited of Toronto, with no fewer "than 26 slices in a loaf."

By 1940, Wonder Bakeries Limited had become the maker of Wonder Bread in Canada, along with Hostess cakes and cookies, although local bakers continued to be the actual manufacturers.
 New products were introduced that included Wonder Melior, "a better white bread with natural wheat vitamins," as well as Wonder Peter Pan Bread, designed to appeal to children.
 Wonder Bakeries also became the maker of Hollywood Bread, marketed for those "counting calories" and trying to keep their "figure."
 During the 1960s, General Bakeries Limited became the maker of Wonder.
Then, in July 1985, Weston Bakeries Limited, a subsidiary of George Weston Limited, acquired certain Ontario assets of General Bakeries, then owned by Dominion Stores Limited, that included not only bread and roll plants but also the trademark for Wonder in Canada.

Over the past decade, Weston Foods has added a number of new Wonder products to the brand's line-up, many of which are designed to appeal to parents and their concern for their children's nutritional needs.
 Among them is Wonder + Invisibles, a white bread with 18 whole grains and designed not to taste like whole grain bread.
 In 2011, Weston Bakeries Limited announced that its Wonder Bread brands will now be completely free of artificial preservatives, artificial colors or artificial flavors.
