Gramma's Candy Store is a retro, diner-style candy shop in Petrolia, Ontario, opened by Terri Denboer in November 2020 that recreates a 'step back in time' atmosphere with bright signage and vintage treats, specializing in classic and nostalgic sweets while intentionally stocking gluten-free, dairy-free, vegan, and nut/tree-nut-aware options to serve diverse local dietary needs.
