I’ll be eligible to apply for US citizenship next month. I’m pretty well settled here and have no current plans to leave. Do I want to move and stay in Canada? At the moment, no… but I like having options. But if i lose my PR, it’s not the end of the world. My interest is if the border officials would even ask you about your PR status if you enter with your US passport .
So to answer your question: I am meh about potentially losing my PR although I’d rather not lose it.
I haven’t travelled during pandemic but prior to I was never asked about PR status (or whether I had status) when traveling on US passport. They may know and not ask because I always travel across border with a Canadian citizen spouse.
