I am also puzzled by various parking regulations in Ottawa. For example,
(1) Parking in a lot with meter on Saturday or Sunday, FREE or NOT?
(2) Parking in a lot with sign of permit holder or handicaped only on Saturday, Sunday or holiday, OK or not?
(3) Some lot with sign "8:00 am to 9:00 pm, 1 hour", does it mean beyond this time limit, parking over 1 hour is allowed?
Thanks for help.
