Shoppers in Toronto will want to remember to bring their own bags to the grocery store starting Monday.

The city now requires all retail stores to charge a nickel for single-use plastic bags.

The five-cent fee is aimed at curbing the use of the throwaway bags — and many stores are already charging for bags.

Many environmental groups, such as the Recycling Council of Ontario, say the fee puts a price tag on pollution.

Canadians currently take home about 55 million bags from stores every week.
