Is travel with a passport open to Canada now?
Thanks for the A2A. The question is not clear. With the exception of the U.S. until recently, it has always been necessary for anyone coming from outside the country to have a passport. If you are asking if there are no restrictions on travel other than holding a passport, then there are a lot, depending on what passport the traveller holds and what Covid-related restrictions are in place. They keep changing. I suggest visiting government of Canada website to see what are in place right now and then keep checking.
