| Legal structures and especially state or state sponsored entities in Canada work much differently than in the US. The ICBC has a literal state sponsored monopoly over car insurance, titling a vehicle and driver licensing, whereas in the US no state handles car insurance, while titling a vehicle and driver licensing are not necessarily the same state organizations. This state sponsored vertical integration enables abuse of authority in cases like https://www.reddit.com/r/nottheonion/comments/xa9j3x/church_... Whereas here in the US I know many people that mix and match between different states DOLs and DORs for a variety of reasons, and your not going to get stuck with the same stubborn employee who can control every facet of your ability to identify yourself and also legally drive a vehicle on the road. The DUI checkpoints up in BC are wild too, I'm glad they are banned in Washington and Oregon. Suspicionless stopping of cars en masse followed by interrogation by police seems like an overreach. |
I’m pretty sure Canadian DUI checkpoints are limited to interrogations about alcohol/drug intoxication (edit: and a few matters regarding the vehicle itself) unless something else is offered/observed.
Supreme Court basically agreed that they are warrantless and detainments without reasonable suspicion, but considered them acceptable for the purposes of preventing drunk driving so that’s all the carve out it for.

(Worth noting that Canada’s constitution is basically toilet paper for a lot of things because a judge (or politician!) can override a lot of it)
