Thanks for those links. Very interesting! I realize that I didn't reply to your initial question about what there might be to stop a person from crossing between the US and Canada along 0 Ave. There are apparently sensors in the border ditch (there is a ditch), and there are cameras. I noticed U.S. Customs and Border Protection vehicles at random places just inside the U.S. People in the area seem very aware that there's a border there, and I wouldn't be surprised if a fair number of folks are caught because locals report unusual happenings/sightings to authorities.
Exactly! I was surprised. I visited there with a Japanese friend, and he didn't believe it just said "Pets on Leash." But he didn't go to check, for fear it would mess up his passport.

This picture is taken facing east/southeast from 0 Avenue in Langley, BC, Canada into Whatcom County, WA, USA (near Lynden). I like the juxtaposition of the speed-limit signs. The U.S. speed-limit sign is not a standard U.S. sign, though. It's a Whatcom County sign stating that the default speed in Whatcom County is 35 m.p.h. unless otherwise posted.

I'm facing southeast (more eastward than south) on the Canadian side of the U.S./Canada border at Peace Arch park. A piece of the Peace Arch itself can be seen in the lower right part of the picture.
