The public we mention is not what the government uses for its own employees. That is the coverage they provide for their population. The various provinces have public insurance for certain groups in their population, such as seniors or people with low incomes. That's the cost for those groups. For example, seniors in Ontario get their prescription drugs free and that costs the Ontario government a certain amount of money. That $13.1 million covers them.
