YYZ appears to be behind glass doors designed to open in only one way, however you just need to take the escalator up stairs and back down again to get into the baggage area.

YVR is protected by this fake field stone wall, (or more likely fake river stone wall). More recently they tried to install those swing gate things you find at drug stores entrenches.

YYC missed the memo on hiring magicians for baggage claim. So it is equally as wide open as Montreal.
