Canada has recently eased their travel ban and now allow Siblings and grandparents to visit family who are Canadian citizens.
Surly this would be a positive move for the US Government to consider. My son is a US citizen. My daughter is a green card holder. I have 3 grandchildren living in the USA and have not seen them since January. More than happy to self isolate and arrive with a negative covid test. I think this is the way forward to reunite families as the festive season aproaches.
