I should be more precise with my comments. Some pieces of domestic ones have been slow to deliver.
When you look at face shields, you will see that it's been very quick—quite miraculous, frankly—and really on board quickly. If you're getting into manufacturing ventilators for the first time, you need supply chains and raw materials, and that takes time to stand up. I would say that for face shields, it's absolutely very efficient, and for ventilators, longer.
Other factors that would slow an industry down in terms of ramping up include bringing your workforce back. Making sure your workspace is properly organized to reflect the COVID environment is part of the story as well. Access to raw materials is big. With regard to gowns—an area where the Canadian industry has done a fantastic job of responding—the material used to make traditional gowns was not readily available, so Health Canada, as a regulator, approved some additional materials, different types. However, again, to go and get that takes time.
It really depended on the complexity of the good being manufactured.
