Yes, Hamilton has seen tremendous growth. It is primarily a freighter airport, and it has had a lot of growth throughout the pandemic. Really, the national trade corridors fund has been helpful in expanding the infrastructure.
I think that what we've seen throughout the pandemic is that, because they've expanded that infrastructure, they were able to grow. We've seen that at other airports throughout the country, such as in Halifax and Edmonton, with projects that were approved years ago and have been under way. Now they have that expanded apron space, and they were able to receive some of these shipments by air cargo to keep our supply chain moving. Air is playing an increasingly important role in getting exports to market and in getting goods into Canada.
What we need to do is keep investing in the national trade corridors fund. Our airports have only seen about 18 projects approved since it was announced in 2017, with just over $220 million. Much of that was for small airports to pave their runways and things like that. I think we should focus on cargo needs to improve our supply chain for Canada moving forward. Some of our airports have asked for a dedicated air cargo line item in the national trade corridors fund of about $100 million a year to really move forward and to invest in the future so that our airports are able to play the important role they've been playing throughout the pandemic.
