The elimination of free single-use plastic bags will be rolled out across Canada starting February 9. Customers who request plastic bags at checkout will be charged five cents per bag.

Walmart (WMT) recognizes that it’s asking customers to change their shopping behavior, Lee Tappenden, chief operations officer of Walmart Canada said in a statement. “[B]ut we strongly believe that removing plastic film from our waste stream is imperative to reaching our goal of zero waste and will encourage our customers to broaden their already existing waste-reduction efforts.” He said that in other international markets, fees encouraging customers to use reusable bags has reduced single-use plastic bags by more than 50%. “Similar programs here in Canada have reported comparable successes,” he said.

In October, customers in England faced a plastic bag fee for the first time. It was the last country in the United Kingdom to adopt a plastic bag ban. At the time of the ban, consumers in England used 12 plastic bags per month. In Wales, where a bag tax has been in place since 2011, shoppers used two bags per month.

Tesco, Britain’s largest retailer, said in early December that the use of plastic bags have dropped 80% since England’s ban went into place.

In the U.S. some states have adopted similar bans. In July, grocery stores in Hawaii were banned from distributing plastic bags and about 150 cities and counties in California have instituted similar rules. A city-wide ban on plastic bags also went into effect in Chicago this summer.

In announcing its plastic bag ban in Canada, Walmart cited a study introduced at the 2016 World Economic Forum in Davos, Switzerland last week that says that by 2050, the ocean is expected to contain more plastic than fish by weight if there are no efforts taken to reduce plastic pollution.
