As a high-level answer, in terms of capital and equipment, I think the constraints are less daunting. In the area of raw material, this is where you can follow a supply chain all the way up and find that you have to go outside of Canada for certain critical components, particularly chemical components or elements of different products that are required.
For example, in the pharmaceutical industry, the APIs used to create pharmaceutical products are made in other countries. We're sort of chasing these different issues on a daily basis. One thing I've been pleased with is that, to maintain our testing effort, we've unlocked supply in Canada of chemical reagent manufacturing. If we hadn't done so, we would have heard about a constraint in testing related to the manufacturing or production of reagent in the country, but we've been successful in bringing a number of companies into that market to supply our domestic needs. It's a very critical question.
