Mandatory pregnancy warning labels on alcohol could save Canada significant costs associated with fetal alcohol spectrum disorder (FASD). While producers argue labels would cost $400 million to implement, the economic burden of FASD in Canada is much greater. Estimates show the cost of FASD diagnoses is $3.6-5.2 million annually, and the total national cost of FASD is $1.3-2.3 billion including lost productivity and child welfare costs. Warning labels could help reduce FASD incidence and its substantial economic impacts.
