Ontario is being urged by environmentalists and farmers to charge a deposit on plastic bottles.
Environmental Defence and the Ontario Federation of Agriculture have written a joint letter to the government, saying a deposit would boost recycling rates and also help protect the Great Lakes.
Ashley Wallis of Environmental Defence says recycling isn't working and more than half of the plastic bottles sold in the province don't make it into the blue bin.
Meanwhile, she says about 80% of litter in the lakes is plastic.
She says any unredeemed deposits could go into a fund dedicated to protecting the Great Lakes, which could raise as much as $100,000,000 a year.
