The COVID-19 pandemic

Of all places that should require a passport, I think public transit should be one of them. Simply because you're in a small area with poor circulation, which is the breading ground for covid-19. Some transits (like the TTC) do enforce mask wearing, but the GRT doesn't.

Transit vehicles generally have excellent air circulation, far more than inside any building. For example, Metrolinx has a blog post on this for GO trains https://blog.metrolinx.com/2020/08/27/ai...rd-trains/ . Or here's a good NYTimes visual on NYC subway vehicles, the airflow patterns on ION are similar https://www.nytimes.com/interactive/2020...virus.html

Most public transportation vehicles are designed this way. Even planes, where many assume you're breathing recirculated air, actually bring in hospital levels of fresh air, and are designed with airflow patterns that minimize transmission.
