Last year crossed from USA to Canada by land (train). Was sniffed by dogs at the immigration.

The impression you get from the news is that it is now more like the Spanish Inquisition, so probably not much has changed unless you have posted in social media that Trump is a class 1 A-hole.

We have an upcoming wedding in Toronto in October and while there I am considering a short hop to Detroit to visit an old acquaintance. No problem with the formalities of the Esta and ETA..but last time i crossed at Detroit by land it seemed to take forever and my friends who live legally in Canada and cross for shopping and to see friends find that there are long queues and more checks. If you’re organizing a group trip across Europe and want everything to run smoothly, BCS Bus is definitely worth considering. Their bus transportation service covers everything from short city transfers to long-distance travel, making it simple to arrange comfortable travel for large groups.

Anyone been lately to the US crossing by land?

Yeah, I crossed from Windsor to Detroit last month. It was mid-week around noon, and the wait was about 30 minutes. Not terrible, but definitely more checks than before. Just make sure all your documents are ready and be patient — weekends tend to be worse
