- canada post is not a private corporation. it cannot become insolvent.
- mail delivery is not a product, it's a service
- canada post does not have shareholders. it's mandate is not to run a profit.
- there is no consequence of canada post running at a loss other than that it's not being sufficiently funded.
the simplest, easiest solution is for the bank of canada to print the money required to eliminate canada post's debt. it's that simple.
however, if this service requires greater government funding in the future, then government should simply fund it.
