I didn't travel much, but I realized that there was once in 2015, I came back to Canada from US via a border entry at Buffalo, the border officer did put any stamp on my passport. But on my passport, I have a stamp from US border office at the date when I entered US.
Looks like the same thing happened to my husband as well. Is it normal?
