New Anti-Smoking Law PDF Print E-mail

Fighting the primary cause of avoidable death and disease in Ontario

The Smoke-Free Ontario Act came into force in May 2006. Smoking inside any enclosed workplace is now illegal. 


(bld)Smoking is banned in all enclosed workplaces.(endbld) An area is “enclosed” if it is covered by a roof and has more than two walls. This means it’s illegal to smoke in the following areas: 

  • buildings, whether completed or still under construction
  • jobsite trailers
  • company vehicles 

It is not illegal to smoke:

  • outside
  • in an outdoor smoking shelter that has no more than two walls and a roof
  • inside a building that has no more than two walls and a roof or ceiling
  • in a partially finished structure without a roof
  • in a vehicle enclosed only by a cage or completely open to the outside air.

Fines are up to $5,000 for an individual and $10,000 for a company. 
The new law is the cornerstone of the provincial government’s Smoke-Free Ontario Strategy.


Do You Smoke?
Tobacco smoke harms the health of both smoking and non-smoking construction workers. 

Workers who are exposed to toxins such as asbestos, silica and lead increase their chances of getting disease from these substances by being exposed to smoke. The risk is increased by synergetic biological mechanisms (hazards working together) or by accidental exposure through the mouth or skin when smoking with contaminated hands. 

Smoking is the primary cause of avoidable premature death and disease in Ontario (1). Tobacco causes 16,000 deaths in Ontario every year and costs the economy at lease $1.7 billion annually in health care. 

Tobacco smoke causes lung cancer, heart disease, stroke, chronic bronchitis, emphysema, asthma and impotence, among other diseases and conditions.
