Thanks for that information. Maybe I could just hear what the costs were this year so far for the Hay River and Yellowknife situations. On a looking-forward basis, when our school roofs started to collapse because of snow loads, unexpected snow loads, we adapted by changing the standards that construction had to meet for the roofs of schools. Are there those sorts of adaptations happening in the construction of runways to deal with these eventualities or probabilities? Thank you.
