A lot of the guidelines were stipulated by the local medical officer of health from Toronto public health, Dr. Eileen de Villa and her team, to make sure they were following the standards and protocols that were in effect during their time. I think they were in the modified stage two before they moved into the red zone, and now subsequently into the lockdown zone. Even now their standards have shifted a bit, but they were asked to do the proper minimizing of gatherings indoor and outdoor, as well as proper distancing and masking and limiting the access points, and as I noted in my comments already, ongoing cleaning of surfaces and keeping people moving through so there wasn't a congregation of larger numbers in any setting. They would have taken them from their medical officer who was specific to the zone they found themselves in.
