Exposure to second-hand smoke puts children at greater risk of developing asthma. Children with asthma who are exposed to second-hand smoke have more attacks and the attacks are more severe.

Why is there a Smoke-Free By-law?

The by-law was adopted after extensive public consultations and is intended to protect residents and workers within Durham Region from the serious health hazards associated with exposure to second-hand smoke.

When does the by-law come into effect?

Durham Region's Smoke-Free By-law comes into effect on June 1, 2004.

What does the by-law say?

As of June 1, 2004, all public places* and workplaces must be 100% smoke-free.

Public Places

A public place is any indoor area to which the public has access and includes (but is not limited to):


A workplace is any enclosed, indoor area where an employee works.

*Bingo halls, racetracks and casinos are permitted to have a designated smoking room.

What about a smoker's right to smoke?

First and foremost, this is a health issue. Breathing second-hand smoke is a proven and serious health hazard. The health of everyone, including workers, needs to be protected in public places and workplaces.

Won't a Smoke-Free By-law hurt restaurants and bars?

Numerous independent studies have shown that when smoking is restricted or prohibited in bars and restaurants, they don't lose business. There may be an initial adjustment period, after which businesses return to their usual level of sale. Many even increase sales.

There is strong community support for more smoke-free public places. For example, a recent Health Department survey shows that 83% of Durham Region residents support a by-law making restaurants 100% smoke-free. (Rapid Risk Factor Surveillance System, 2003).

Is ventilation an effective way to remove tobacco smoke from the air?

Since there is no safe level of exposure to second-hand smoke, an adequate ventilation system would have to remove all tobacco smoke from the air. Currently, there is no ventilation system that is capable of removing all tobacco smoke from the air. Therefore, ventilation may dilute tobacco smoke, but it will not eliminate the health risk.

Are designated smoking rooms allowed?

Bingo halls, racetracks and casinos are permitted to have a designated smoking room.

Are there any exemptions to the by-law?

A private club may allow smoking if it has no employees and if the general public is not allowed in the facility. The private club must therefore be for members only and have volunteer members serving them in order to allow smoking. Any facility that is a private club and rents or otherwise invites the public to its premises for a function must comply with the by-law and therefore not permit smoking while the general non-member public is on the premises.

Is smoking permitted on outdoor patios at restaurants and bars?

Yes, as long as the outdoor patio is not enclosed. That is, not closed in by a roof or ceiling and walls.
