Thank you to our witnesses for being here.
Thank you for the answers you are giving us, even though, personally, I find myself with more questions than answers.
In the arguments, it is always traditional contracts that are compared. We don't hear anything at all today about the public sector, quite simply, for undertaking work. Failures have been mentioned concerning the government, and P3s seem to be the solution. However, I have difficulty with the fact that we're not talking at all about correcting failures within government.
My question is for Mr. Mackenzie, whom I thank for being here today.
A major argument for promoting P3s gives the illusion that risks are shared with the private sector. However, in reality, when P3s run into major problems, it's the public that suffers the consequences. For example, in cases of bankruptcy or force majeure, it is the public that pays the bills.
Can you talk to us about what you call walk-away risks, and give us a few concrete examples of when costs for taxpayers and the public sector turn out to be much higher than expected?
