Thank you, Mr. Chair.
I'll follow up on my previous question, which basically relates to the true needs of the communities for harbour infrastructure and the realities the north is facing today as a result of climate change.
Several guests have pointed out that there are changing ice conditions. From an engineering point of view, the destruction of a wharf in these kinds of climates is based on loose ice. When you have shorefast ice--quick freeze, quick thaw--from a structural point of view, that's the best thing you can have. Frequent thaws and loose ice in the ocean that is drifting through currents and tides causes the most amount of damage to a wharf structure.
Could you comment on the true needs of your communities in terms of a multi-use wharf? Again, that's for inshore fishing, inshore hunting, offshore fishing through the use of factory freezer trawlers and other things, the supply of goods and services, and industrial services as well. Could you provide some comment about the effects of climate change and the precise impact on engineering to these structures? Would you be able to give the committee some insight about these things?
