Funny, but look at it from the perspective of those actually involved. Canada doesn't have a magic spreadsheet of all the people currently allowed in the country. Nor does the US, or France. They have to check up on visas and such.

And because this person is currently in custody, they cannot be released until they know there aren't any outstanding warrants in any of the three countries involved.

But this does not avoid the fact she violated the law. In legal terms, she deliberately crossed the boarder. She didn't knowingly violate the law, but this isn't someone forced across the boarder against their will. "I didn't see the marker" isn't actually an excuse. Someone in the US has to actively decide not to prosecute. That decision too take time, and won't start until such a person's identity and status has already been assured.

> Someone in the US has to actively decide not to prosecute.

There’s no autonomous machinery that will prosecute someone unless it’s turned off. If nobody in the US did anything, then she would have jogged back into Canada and never have been aware that she stepped outside of its boundaries in the first place.

So, no. Action would have been required to prosecute. No action would have meant no prosecution.
