An online store has launched in Ontario selling groceries and household items from Loblaws in containers it will take back and refill — a test of whether Canadian consumers are ready to change their habits. Industry-watchers say it is breaking ground for reusable packaging.

The store, called Loop, launched in Canada on Feb. 1, in partnership with supermarket giant Loblaws, and offers items like milk, oats, ice cream and toothpaste for delivery in most of Ontario. Loop is already operating in the continental U.S., the U.K and France. 

Included so far are some products from well-known brands such as PC sauces and oils, Häagen-Dazs ice cream, Heinz ketchup, Chipits chocolate chips and Ocean Spray cranberries. 

"The goal is really validating that this is something the Canadian public is interested in," said Tom Szaky, founder and CEO of Loop and its parent company TerraCycle.

Unlike existing small no-waste retailers, they want to offer "your favourite product at your favourite retailer in a reusable and convenient manner."

The involvement of a huge retailer makes the launch notable in terms of scale and who it will reach, said Tima Bansal, Canada Research Chair in business sustainability at Western University in London, Ont. 

"I think it's at the scale that's needed to create the change in the community in Canada more generally," she said.
