The city will begin issuing warnings starting Thursday to highlight its new ban on all water pipes, including hookah pipes, in public places.
The ban, which takes effect Thursday, builds on existing city bylaws, which came into effect in 2012. Those bylaws prohibited the use of water pipes on outdoor, municipally-owned property including parks, beaches and recreational playing fields.
