EDC isn't tax-payer funded but rather tax payer backed. If EDC hasn't risked their portfolio correctly and they face insolvency then tax payer money flows in - just like the CMHC.
At some point tax payers seeded the start up capital of these and other Crown Corporations, but that was a long time ago (decades ago on both counts) and they've returned (in the form of earnings surpluses) money back to the government ever since.
So the reverse is actually more true - Allana will pay interest which profits Canadian taxpayers, including the Allana haters.
Just saying.
