Great Lakes Refill Co. is Sarnia-Lambton's premier zero-waste grocery store. Founded in July 2018 by sisters Melissa Matthews and Lisa Ladouceur, the brand was born out of their passion for the environment and their desire to address the global plastic crisis. Inspired by the presence of plastic in the Great Lakes, which are a vital source of fresh drinking water, they set out to bring a wave of change to their community.

Great Lakes Refill Co. is committed to providing package-free solutions and education to promote reduced waste living. The brand received recognition for its dedication to environmental stewardship by winning the 2019 Small Business Stewardship Go Green Award from the City of Sarnia.

Initially offering refill products for personal and home care, such as shampoo, conditioner, and cleaning solutions, Great Lakes Refill Co. expanded its offerings to include bulk and prepared food, home essentials, and a wide range of sustainable goods. By shopping at Great Lakes Refill Co., customers can feel good about reducing their plastic waste and supporting a brand that prioritizes environmental sustainability.
