Green Toys is one of our favorite American-made, eco-friendly toy companies. But even the best companies can run into problems, which is currently the case due to some faulty wheels. Green Toys in cooperation with Health Canada have issued a voluntary recall of the Green Toys Mini-Vehicles sold in Canada recently. This recall involves the mini toy vehicles made by Green Toys in shapes of a race car, a police car, an ambulance and a taxicab. While there have been no reports of injuries, the wheels on the cars may detach, posing a choking hazard to young children. If you’re in Canada, and have bought any of these sets, you should take the toys away from your child immediately and contact Green Toys Inc. to receive a full refund by calling (888) 973-3421. These toys were only sold during May 2012 and June 2012. The product numbers affected include: MVHA-1014, MVFA-1022, MAMW-1015, MTXY-1021, MPCB-1020, MFBR-1018, MVSA-1016.
