Thank you very much, Mr. Chair.
Thanks to all of our witnesses for what has been an interesting discussion so far.
I want to pull back a little bit and ask a high-level question. This study is a very interesting one because the supply chain is so complex. It has so many different players and each of those players brings a unique piece to the table. In many ways, I think we could have been having this discussion five years ago and it might have had some similar aspects to it.
Something has happened over the past two years, and particularly over the past year, that has changed the discussion and has made people acutely aware of the supply chain. I don't think many Canadians had ever heard the term “supply chain” until the past number of months. Now, all of a sudden, it seems like we have a major problem that needs addressing.
My question is really about risk and looking forward at the coming five or 10 years. What do our witnesses here today perceive as being the greatest source of risk to the Canadian supply chain? We've heard of lots of sources of risk, but if you could put your finger on the single biggest source of risk to Canada's supply chain in the coming decades, what would it be?
Perhaps I'll start with Mr. Gooch from the port authorities. When the ports talk about risk in the longer-term future, what's the biggest one that comes to the fore?
