Hi, yes you can enter Canada through the US-Canada land border as many times as you like until you receive you PR card. I just came back from Mexico last week and I flew out of Buffalo airport using my eCOPR to enter back into Canada.Hello, we are also in the same condition and would like to know where we can see this information that we can travel via car to US without PR card and reenter with eCoPR?
Please do share the link for the same asap.
