Certainly. Landslides are the usually rapid downward movement of a mass of rock, earth, or artificial fill on a slope. But slumping soil isn't under debate. I was talking about 'landside', which is the common term used to definite the public area of an airport (pre-security). Conversely, airside (post-security) is the term used to describe the sterile area accessible only to airport staff and ticketed passengers.

Your earlier post inferred that crossing the security threshold within an airport might result in moving from an area of provincial to federal jurisdiction, therefore liquor taxes etc might differ or not be valid. This is not true. Provincial taxes are still applicable on federally owned property.
