It is because they are targeting the vote of youth and families (who have children). Coverage for the sick adults between 25-45 cost just as much as the current $4B/year Ontario spends for 65+ Pharmacare - the province cannot afford it with its $300B and growing debt. The kiddie pharmacare only costs 465M/year and likely produces a better bang for your money in terms of vote pandering. Any expansion of Pharmacare requires the Feds to intervene and facilitate a nationwide plan that they are likely reluctant to do because of their own crazy deficits.
