 Greg, what's happening with Zengard? Hi Tracy, good morning. Zengard continues to move along. We're on the path to commercialization. As we made the market aware and early this year, we received our results from the ISC Challenge through the National Research Council of Canada. We had spectacular results with Zengard in indoor air quality on HVAC systems. We had a five-fold improvement in viral filtration efficiency, which is absolutely groundbreaking in this regard. There's been no other antimicrobial coating that's demonstrated any effectiveness anywhere close to what we were able to achieve. So once we received that, we were fast on the approval process. We have to go through a regulatory approval process through the Pesticide Management Regulatory Agency here in Canada. We have been working with them for the last number of months towards getting regulatory approval for Zengard coating on HVAC filters here in Canada. It's quite an extensive process that you need to go through to get approval through PMRA. They had over 95, 97 tests that are required to get approval. So it's a very, very heavy lift, but our team has done an absolutely amazing job. They've been wearing their fingers to the bone getting this submission underway. So we're in the middle of that process now. I don't want to give any timelines with respect to when we think we will get approval, but we're very confident that we will, given the fact that Zengard has already been approved by another branch of Health Canada. We have been doing a lot of work in the market with not only end customers, but filter manufacturers as part of the ISC challenge with the government. They're allowed to procure directly from us because we were successful in the ISC challenge. We've been having a number of discussions with them more to come on that front. We have been talking to other governments across Canada, provincial governments, municipal governments. So we're making tremendous progress. But what's really fantastic to see is we're starting to see demand from end customers. So private sectors that are now reaching out now that they've heard about our product. The pandemic has really created a heightened awareness around indoor air quality, the levels of indoor air quality and improving it. And we have a solution that is not only effective at killing pathogens, but it does it in an incredibly green way. So there's no additional energy requirements to get the substantial improvement. And it's incredibly safe. So we are very, very happy with where we're at. And we anticipate to see a significant ramp up in revenue in the not too distant future in this product.
