Bylaw officers can now issue fines to Ottawa residents not abiding by the anti-smoking bylaw.
The provincial offence notices can carry fines up to $300 for anyone smoking on patios, beaches, city-run parks or other municipal properties.
The bylaw's warning period began April 3 when the city first passed the smoking ban.
The city also added hookahs, Middle Eastern water pipes that can be used to smoke herbal products other than tobacco, to the smoking ban last week. They are allowed on patios, however.
