I really miss making my own garlic bread with a fresh baguette from our local bakery, but with those now off limits thanks to cross-contamination concerns, I've been searching for a nut-free alternative. While none of the frozen garlic breads I've looked at before contain actual nuts as an ingredient, most still carry the 'may contain' warning. Dempster's however, does not. Still, for some reason I'm not convinced. While their website does not contain any allergy information, a call to the parent company, Canada Bread, clears it up. There are no nuts, or traces of nuts in the garlic bread.
Always do your own research.
