WATCH: Thin plastic grocery bags are now a thing of the past in Montreal

Tuesday marks the end of the grace period for merchants to adjust to the single use plastic bag ban.  

The Super Marché PA chain has been preparing for today since the changes were announced in January.

They used up all their single use plastic bags and no now only sell thicker reusable bags.  Owner Taso Erimos thinks the city should've gone further.

"Realistically I would rather there were no bags at all rather than 50 microns" says Erimos. "But the law is the law."

He says though many people remember now to bring their own bags, many will pay the 10 cents for the plastic bags that still wind up in the garbage. 

Merchants caught handing out the thin bags can be fined anywhere from $200 to $4,000.
