Please Help! | Recommendations as a Transfer

Hey everyone!
I am a current 1st-year student of the University of Ottawa and I am looking to transfer to a top 50 school in the US for Fall 2021. My current major is PoliSci, but I would want to change it to something like International Relations, Behavioural Economics, or Business. I have good grades and extracurriculars; however, I don’t have any recommendations. All my classes have not only been taught remotely but they were also prerecorded. I don’t know what it will be like for my next semester, but I am not expecting any changes. Basically, I’m not doing Zoom University, I’m pretty much doing YouTube University. I might be able to ask a TA to right one, but it would strictly be based on grades and they are technically not teachers so I’m not sure it’s the best idea. I also thought about asking a teacher from high school, but it’s really not ideal. What should I do? Should I even submit recommendations? Any suggestions for schools with no required recommendations? Can anyone relate? If so, what are you doing?
Thank you in advance,
Margot

I’m asking my PI from a research lab to write one of mine (not sure if that is an option for you, but something to consider), but I’m in a similar situation on the other one. My HS rec letters were pretty good, would colleges consider accepting them due to COVID?
