TORONTO — Environmentalists and parents are calling on the province to ban potentially toxic plastic baby bottles, rubber duckies and other children's toys.

Rick Smith, with Environmental Defence, says certain kinds of plastics contain a harmful chemical that is used in everything from children's bath toys to sippy cups.

He says the chemical is unnecessary and it's time the province took action by banning the substance.

Smith says a ban should be the Liberal government's top priority when the legislature reconvenes next week.

Environmentalists, parents and children's activists are holding a rally tomorrow on the legislature lawn to push the province into action.

Andrea Page, owner of FitMom, says the rally is a good first step and the province has a moral responsibility to protect the health its children.
