Thank you, Mr. Chair.
Let me review what I think I've heard today. It's the opinion of Mr. West that without Canadian production of isotopes, there is no reliable production of isotopes globally, so if Canada doesn't stay in the game, somebody has to move quickly. I have a follow-up question on that in a minute.
Then I've heard opinions by three people on how we should produce those isotopes. Mr. West says fix MAPLE and get it going. Mr. Duguay says a much better method is to use linear accelerators, and Mr. Waddington says fix NRU. So we have disagreement on the answer to the question.
I'm not going to seek clarification on which of you is correct, but I would like to ask a question not only of Mr. West but anybody else who has information to bring to bear on the supply, because I'm not hearing a clear answer on the supply question. Just how short are we worldwide? What are the implications of what's occurring? What is the supply now? What is the potential for various timeframes in the future? And particularly, the minister has talked about a five-point plan to ensure the isotope supply. Do any of you know what that five-point plan is, and does anyone have an opinion on whether it can or will be effective?
