Heinz [Seriously] Good Mayonnaise is the brand's premium mayo line, positioned as a richer alternative to standard sandwich spreads. The Canadian product page lists vegetable oil, liquid whole egg, vinegar and seasoning, with no artificial flavours or colours claimed in Heinz marketing.
Kraft Heinz Canada states that ketchup, mustard, vinegar, barbecue sauce and mayonnaise-style products are among the lines prepared in Canada, with major sauce production in Montreal, Quebec. That applies to many Heinz bottles sold here, even though Kraft Heinz is an American public company.
For origin-conscious shoppers, the split is familiar: Canadian plant jobs and local bottling, US corporate ownership. Heinz recommends it for sandwiches, burgers, grilled cheese and dipping.
Contains egg. Refrigerate after opening. Serving suggestions on the Heinz site include fries, tenders, rice bowls and wraps.
