There are two elements to the amounts being brought forward for the Champlain Bridge in the supplementary estimates (A). The first is a settlement agreement that was announced by the Government of Canada back in April as a result of negotiations with the builder of the bridge, Signature on the Saint Lawrence, to cover the transport of particularly large pieces of steel and bridge structure. There was an agreement on a way forward for that. Then there was an agreement to accelerate some of the work. As a result of that, some additional costs were incurred. So that formed a portion of the monies sought through these supplementary estimates (A).
The other portion of the amounts in these supplementaries is the re-profiling that I mentioned earlier. Every large project such as this will have a contingency reserve, monies that are available should there be changes in foreign exchange, in inflation, in the value of our dollar, etc. To this point, those funds have not been utilized for the project, but they're available. They were re-profiled from previous years when they were in the estimates into this fiscal year. They exist to enable the close out of the project.
