Thank you for the question, Mr. McCauley.
Having been in business for the better part of 20 years, and with primarily an international focus to date, we have quite an extensive supply line all around the world. Traditionally, the vast majority of our supplies would come from North American sources, Canada and the United States, with some supplementation from parts of Asia and parts of Europe. We have not encountered any serious problems with that existing supply chain, but with a mind to the future, we are working with our government partners, such as ISED and NRC, to try to move as much as possible of that supply chain within Canadian borders. We have an active program with them right now on doing exactly that.
I guess to answer your question simply, we have not encountered any significant issues thus far as a result of our very extensive supply chain, but nobody has a crystal ball, which is why we're going to try to shore it up to try to be 100% within the borders.
