The Ontario government debt is the net amount of money the Government of Ontario has borrowed from the general public, institutional investors and public-sector bodies. As of March 31, 2018, the Ontario government's total debt is projected to be CDN$348.79 billion.
Ontario taxpayers must pay $21.2 billion in government debt interest this year. Government debt imposes real costs on individual Canadians and their families in the form of interest payments. Governments must pay interest on their debt—it's not a choice.
