Passing through to the US for a week last year@ Blaine Border Crossing, we declared some fruit in the truck( after being asked ,purchased at Costco ) anyway they searched our vehicle for any other contraband and said "if they had found any other fruit we could have received a fine of $300 of each occurrence" .
That was at the first time we had been stopped and searched , We lost our 2 bananas .
We had attended a Canadian Snowbird meeting a few years ago where the cautioned the same - beware of what you talk about when nearing the border because of technology to hear what is said from a long distance.
I am wondering if they are more concerned about what Canadians are bringing back in, than us from the states coming in for a vacation. We crossed over at Osoyoos last year and I had been told by my brother, who goes up there annually that they wouldn’t ask about food at all. However, at the park we stayed at the night before we crossed, we talked with multiple folks from Canada and they said you can’t take anything across and risk the fine you mentioned if you do get caught with something. I was bummed as I had a large amount of tomatoes from my garden, so I made a huge salad with my lettuce, tomatoes and avocados, hoping they wouldn’t take a pre made salad, and ate several cherry tomatoes and gave a bunch away. When we got to the border the only thing they asked about was if we had guns! I’m curious about other folks from the states have experienced. Coming back to the states, though, US customs was concerned about what food we were bringing back in.
