Was speaking to some Americans a week or two or go who’d had to go through an ICE or DHS (not sure) checkpoint on a northbound interstate, just before reaching the Canadian border. Apparently Canada was cooperating too, keeping an abnormally small number of booths/lanes open to keep things nice and slow. These were definitely US agents, so it was not a Canadian operation, or if it was it was in cooperation with the US.
(Since this is second-hand, assume a suitable level of garbling of details… but I’m sure of the basic fact that these people went through an ICE or DHS checkpoint just before leaving the United States.)
