Montreal too just banned lightweight plastic bags

On 1 January 2018, Montreal became the first major city in Canada to ban lightweight plastic bags in retail stores.
Montreal's new law prohibits the distribution of plastic bags with a thickness of less than 50 microns (0.05 millimeters) - very thin bags that are commonly used in businesses.
Businesses will have until 5 June 2018 to comply with the newly-established rules.
A few countries worldwide have already enacted similar bans: France, Italy, and Rwanda among them. In the US, Hawaii and California have statewide bans on plastic bags.
