It is not just a US licence that is surrendered, it happens for others.terem-teremok said:Replacing US DL with a Canadian one.
Why would DMV in Canada withhold my US driving license? What's the reason? What are they going to do with my US driving license? Would they communicate with DMV in US? And about what??
You are only meant to hold a single licence.
Recently an immigrant was stopped in Ottawa, the police found that he was carrying two licences, one from Ontario, and another from his homeland (obtained by lying about a lost licence). The homeland licence was taken by the police, he was warned (no fine).
Yes they can communicate with the DMV, about licence status.
