I think when it comes to preparing for fall online classes, universities are already taking measures to figure out what it's going to look like. Many universities in Ontario and across Canada have already made commitments to being either 100% online or offering a portion of courses in person. I think it's really university specific as to how many of the courses will be online, but I also think it's important that universities take steps to prepare students to be able to learn online, because it is a fundamentally different learning environment from the in-class, lecture-based courses they might be used to from high school or even prior university courses.
