ION - Waterloo Region's Light Rail Transit

[panamaniac]

It's not hard to enforce, but it's expensive. Validated parking would be one way. Straightforward time limits would be cheaper, but wouldn't catch all violations.

That's what I was thinking - the only added expenses would be some signage and employee parking tags.  I wonder, however, whether even something like a four hour limit wouldn't generate complaints from people claiming that it's not enough time.  (I don't know, for me after four hours a shopping mall would have been transformed into a circle of Hell, but I could imagine the consumption-afflicted thinking they need more time!).
