What "loans"?  They aren't "loans", they were handouts that NEVER had any clauses in them to allow them to be repaid.

Quebec didn't even pretend to offer a loan, they purchased a minority equity stake that, at present, has a market value of $0.  The Federal government offered grants with repayment clauses so far off that there was never any expectation that they will be repaid.

Don't blame Bombardier for taking free money, blame our politicians for giving it to them and remember who wasted those billions of OUR money the next time you go to the ballot box.  Until people start voting against politicians who give away massive handouts it's going to keep happening.
