11. The operator of a place or business to which this chapter or a regulation made under the third paragraph of section 2.1 applies shall not tolerate smoking in an area where smoking is prohibited.
In penal proceedings for an offence under the first paragraph, proof that a person smoked in an area where smoking is prohibited is sufficient to establish that the operator of the place or business tolerated a person smoking in that area unless it is established that the operator exercised due diligence and took all necessary precautions to prevent its commission, in particular, by posting clearly visible notices stipulating that smoking is prohibited and by having no ashtrays.
