It's March, 2023. Most of the world has "moved on from COVID" and stopped wearing masks. Here at York University, the YUScreen system was dropped last month and many of the door signs about COVID have been removed. But the fact remains that there are still plenty of reasons to wear a mask* in public. […]
It's Fall 2022 and the masks are off. Well, officially, masking is a "personal choice". Leadership has dropped the COVID ball and is hoping that nobody is going to pick it up again.

In 2020 and 2021 we wore masks. In 2022 we will be wearing respirators. Whether they're official NIOSH N95s, CAN95, or KN95 , for the purpose of general public use we can just call them "N95s". The need for N95s has been clear from the beginning of the pandemic, but for two years most of […]
