Plastic producers will be required to detail the quantity and type of plastic they put into the Canadian market under new rules announced Monday.

The categories covered by the federal government’s new registry are wide-ranging, including packaging for single-use and disposable products, construction, electronics and transportation.

Environment Minister Steven Guilbeault said the registry “will require plastic producers to take more responsibility for the plastic they put on the market.”

“Twenty five per cent (of plastics) are known to be harmful,” said Tony Walker, professor of resource and environmental studies at Dalhousie University in Nova Scotia. “We don’t have data on the other 75 per cent.”
