You have in fact entered the US at that time, and are subject to US law. They can make a non-citizen do pretty much anything they want. You do not have the right to say "my bad, I'll just go cross the border again".
The one exception is Canadian preclearance, since you're still on Canadian dirt at that time (though Canada are thinking about allowing US CBP to detain people attempting to preclear).
