The percentage of non-smokers aged 12 or older who reported being exposed to smoke at home, in a vehicle or in a public place every day or almost every day over the previous year. Results are presented over time, by province/territory and by age group using data from the 2014 Canadian Community Health Survey.

Every two years.
Why measure this?
Annually, more than 800 non-smokers die from second-hand smoke exposure.1 After smoking, exposure to second-hand smoke is the next leading cause of lung cancer.2 It also increases the risk of developing laryngeal and pharyngeal cancers.1 Most provinces and territories, as well as many municipalities, have legislation in place banning smoking in vehicles containing children and/or in public places. Monitoring exposure to second-hand smoke enables evaluation of the impact and effectiveness of such legislation.
What are the key findings?
Self-reported second-hand smoke exposure in Canadian homes and vehicles has been decreasing since 2003. By contrast, although exposure to smoke in public spaces dropped between 2003 and 2009, it has since increased, reaching 13.5% in 2013 (Figure 1.6).
The percentage of the non-smoking population aged 12 or older reporting second-hand smoke exposure in public ranged from 6.7% in Yukon to 15.7% in Alberta in 2014 (Figure 1.7).
Exposure at home was highest in the Northwest Territories (5.8%) and lowest in British Columbia (2.1%). Exposure in vehicles was also highest in the Northwest Territories (11.7%) and lowest in British Columbia (3.5%) (Figure 1.7).
Second-hand smoke exposure was highest among individuals aged 16–19 in all categories (public, vehicle and home exposure) and lowest among individuals 65 or older (Figure 1.8).
Definition: The percentage of non-smokers aged 12 or older who reported being exposed to smoke at home, in a vehicle or in a public place every day or almost every day over the previous year
Numerator: Number of non-smokers aged 12 years and older who reported someone smoking near them every day or almost every day
Denominator: Non-smokers aged 12 years and older
Data source: Statistics Canada, Canadian Community Health Survey (CCHS)
Measurement timeframe: By province – 2014. For overall trends, Canada – 2003 to 2014 (no data for 2004 and 2006)
Including both household members and regular visitors, does anyone smoke inside your home, every day or almost every day?
In the past month, were you exposed to second-hand smoke every day or almost every day, in a car or other private vehicle?
In the past month, were you exposed to second-hand smoke, every day or almost every day, in public places?
Stratification variables: Province/territory, age group (12-15, 16-19, 20-34, 35-44, 45-64, 65+), setting (home, vehicle, public)
Provinces/territories with data available: All provinces/territories
Trend data were extracted from Statistics Canada’s CANSIM Table 105-0501 (Health indicator profile). Before 2009, all rates in this table are calculated including non-response categories (“refusal”, “don’t know”, and “not stated”) in the denominator.
CCHS data are based on a representative sample which is then extrapolated to the overall population.
