Thank you very much, Mr. McGee.
Mr. Trost, your time is up.
Now we will go to our fourth witness, who is joining the other three at the table via video conference. We have Dr. Thomas Perry from the University of British Columbia. He's with the Department of Medicine and Department of Anesthesiology, Pharmacology and Therapeutics.
Go ahead, please, Dr. Perry, with your five- to seven-minute presentation. Then we'll open it up to questions, which could be directed to any of the four witnesses.
