I cannot understand this sentiment. If you commit a crime in a country and don't pay the fine, why would you be surprised if they made you pay the fine next time you crossed the border? Even if it were a parking ticket I wouldn't find Canada's actions here objectionable, and DUI is a lot more serious than that. Unless I've misunderstood the scenario you're describing.

She didn’t commit the DUI in Canada, she did in the US. We were in the country for three days (Victoria) and didn't even have a car, so she couldn’t have recommitted the offense even if she wanted to, which she obviously wouldn’t want to.

She committed a serious crime and didn't pay the penalty which normally in the US comes with additional criminal penalties for non-payment. They would have been perfectly justified to extradite her and take her to jail.

Also how can you say that she couldn't offend again? She could easily rent or drive another.
