Foreign-owned · made in Canada · based in Ontario
Slow-crafted sourdough sliced breads baked in Canada; the brand Gustav Boehringer founded in Unionville, Ontario in 1982 is now owned by Bimbo Canada.

Stonemill Bakehouse markets itself on a fourth-generation family story dating to 1982, but the operating company is a brand of Bimbo Canada, purchased by Mexico's Grupo Bimbo in 2016. Bread is baked in Canada and sold at most major grocers, but ownership profit flows to Mexico, not the founding Boehringer family.
Factors
Ownership
20.0 reportedother 100%
Bimbo Canada's own site lists Stonemill among the 18 brands it produces and states it acquired Stonemill Bakehouse in 2016; Bimbo Canada itself was purchased by Grupo Bimbo S.A.B. de C.V. (BMV: BIMBOA), a Mexico City-headquartered public company, from Maple Leaf Foods in May 2014. The vendor's own site footer and privacy and terms links point to bimbocanada.com, confirming Stonemill is not independently operated; the Boehringer family founding story is heritage branding, not current ownership. Corporations Canada's federal registry search page returned Page Not Found on every URL tried, so this rests on vendor statements and press coverage rather than a filing.

Manufacturing

The vendor's homepage states the bread is baked in Canada, though most loaves start from a sourdough starter culture flown in from Germany. The exact plant address was not named on the vendor's site or Bimbo Canada's site; Bimbo Canada states it operates 15 bakeries across the country without naming which one runs the Stonemill line, so a specific city (reported elsewhere as Scarborough, Ontario) could not be independently confirmed.

The vendor's site names no origin for its wheat flour despite repeated searches of its Our Story, Our Craft, and FAQ pages; it does document a sourdough starter flown in from Germany. Flour, the dominant ingredient by weight, is assumed mostly Canadian given Bimbo Canada's Ontario milling scale, while specialty grains used in some lines, such as chia and quinoa, are typically imported from outside North America. This split is an estimate, not a sourced figure.
- Our Craft | Stonemill Bakehouse vendor_statement “Most of the bread we make begins from a unique sourdough starter flown in from Germany.”
