A significant portion of the private crossings on our network are what we call section 102 crossings, where there's a statutory right to a crossing. In that case, the farmer or the adjacent landowner would not pay any costs associated with those crossing upgrades. Those costs belong to the railway.
With regard to the other private crossings, what are referred to as section 103 crossings—from section 103 of the Canada Transportation Act—there are agreements in place with adjacent landowners. Often those agreements have been in place for decades, and they typically specify the cost apportionment. That's what determines who's going to pay and to what extent for any required maintenance at the crossing.
