It's really difficult to know how long it would take to catch up, because we're still in it. As Gilles said, we could have a second wave and a third wave. It's been mentioned on the call by others as well. We are running at about 70% capacity. We might get to 80% within a year. We might slip back to 60% for a while. I don't think we'll go back to 30% because of lessons learned.
It used to take 10 minutes to do a CAT scan. Now it takes 30. It used to take half an hour to do an ultrasound. Now it takes 60 minutes. The turnover takes time with cleaning. I think we're going to be in this for a long time, as we redefine how we're going to improve our productivity. In the meantime, we'll try to slow the wait-list.
I don't think we're going to catch up to our OECD countries in a hurry without a significant investment of capital and, as Gilles says, HR resources. I think it has also been mentioned on the call by others, too. There's a real challenge ahead of us—
