The fact that other countries have not banned DDT could be of concern to Canadians because DDT sprayed in one country will not necessarily stay in that country.  For example, birds that migrate from other countries to Canada could eat the DDT in other countries.  This could affect Canada if those birds are important to it economically or if many Canadians eat those birds.

DDT tends to accumulate in fat cells.  If DDT accumulates within a mother's body, it could be transmitted to the baby through the mother's milk.  This would obviously increase the levels in the child, but might decrease the mother's DDT levels.
