We used to make things in this country #311 Viceroy toys

Viceroy started making rubber toys in the 1930s in Toronto. They made a wide range of rubber balls, dolls, and cars and trucks. This race car was produced in the mid-fifties as part of an agreement with an Ohio company, Sun Rubber Co. who made the same model in the US. 
The company appears to be still in business today in some form, though now making hockey and industrial products.
