Does Vancouver Have Bad Air? Here’s What Homeowners Need To Know

Does Vancouver Have Bad Air? Here’s What Homeowners Need To Know

Greater Vancouver, British Columbia, a major Canadian city in the Pacific Northwest, is well known for its mountain views, beautiful ocean scenery, huge coffee culture, and of course, rainy weather. Given its surrounding green forests and constant rain, it’s easy to assume the Vancouver environment is surrounded by fresh, clean air. However, according to local air pollution data, this has not been the case during recent years.

Metro Vancouver air quality reports show that our region routinely gets multiple days a year under official Air Quality Advisories, mostly due to ground-level ozone and fine particulate matter (PM2.5). This seasonal air pollution frequently goes above the strict Canadian ambient air quality limits during hot summer months.

So, what exactly is the danger of poor air quality? On average, an estimated 15,000 premature deaths happen across Canada each year because of outdoor air pollution. Overall, a city’s air pollution plays a massive role in the health of its residents and is directly linked to many breathing problems and cardiovascular health issues like asthma attacks and heart attacks. With the Lower Mainland experiencing highly unpredictable smog days, this not only means local officials need to act, but also means residents should stay updated to keep their families safe.

In this article, we’ll take an in-depth look at local air pollution data, common pollution sources, and local BC efforts to fix the problem.

Lower Mainland Air Pollution: The Big Picture

If you’ve ever opened the weather app on your smartphone and scrolled down to “Air Quality,” you are probably familiar with a sliding scale ranging from low risk all the way to very high risk.

To report outdoor air conditions to the British Columbia public, the government uses the Air Quality Health Index, or AQHI, which uses a scale from 1 (Low Risk) to 10+ (Very High Risk).

For an urban area like Vancouver—which deals with a mix of ocean air, heavy traffic jams, and seasonal wildfire smoke—navigating high smog days is a major health concern and points to a bigger, long-term environmental problem.

According to doctors and health experts, these are the typical symptoms of living in an area with poor air quality:

• Coughing
• Wheezing
• Asthma attacks
• Eye and throat irritation
• Burning chest feeling
• Shortness of breath

Breathing in air pollution can also increase your risk of:

• Lung diseases (Chronic obstructive pulmonary disease (COPD), asthma, chronic bronchitis)
• Breast cancer
• Non-Hodgkin lymphoma
• Lung cancer
• Chronic inflammation
• Heart attacks

Most Common Sources of Air Pollution in BC

The biggest contributors to outdoor air pollution in Metro Vancouver include summer forest fires, construction sites, gas and diesel vehicles, burning fossil fuels, and marine shipping ports.

Metro Vancouver’s regular emissions inventory reports, which track toxic particles in our local air, show the main sources of potential cancer risk from local air pollution:

• Diesel Exhaust from commercial trucks and machinery
• Wood Smoke from residential fireplaces and wood stoves
• Industrial Factory Emissions
• Chemical Solvents and Volatile Organic Compounds (VOCs)
• Gasoline Vehicle Exhaust from commuter traffic

The data consistently shows that diesel exhaust—the tiny particles coming out of transport trucks, cargo ships, trains, and heavy machinery—is the main contributor to air pollution in our coastal region.

Local BC Initiatives for Cleaner Air

To fight the dangerous levels of toxins in our local air, Metro Vancouver regional districts created a comprehensive Clean Air Plan.

In addition to provincial air quality regulations designed to lower industrial smog, BC uses grant funding and green incentives to promote a rapid shift from diesel trucks to zero-emission and electric vehicles (EVs). By 2030, regional clean air targets aim to achieve a major drop in total air pollution, lower cancer risks linked to dirty air, and reach a 45% reduction in greenhouse gas emissions compared to 2010 levels.

What Can BC Residents Do to Help?

While the province is working on large-scale fixes, there are things Vancouver residents can do to lower vehicle pollution in the air, such as taking TransLink transit, carpooling, or riding a bike to work, keeping personal vehicles well-maintained, and, when buying a new car, upgrading to an electric vehicle or hybrid.

What Homeowners in BC Need to Know About Indoor Air Quality

The state of outdoor air pollution has a massive, direct impact on your indoor air quality. Given the fact that the average person spends about 90% of their time indoors (whether at home, at the office, or inside a car) and that most of our exposure to air pollution happens inside, it’s crucial to understand how these pollutants get into your house and how to reduce your exposure to them.

Windows, Doors, and House Drafts

When we open our house windows and patio doors, or if there are unsealed cracks in our walls and home foundations, outdoor air leaks into our indoor living spaces. This outdoor air, even if it feels “fresh,” can carry PM10, which is dust, pollen, and mold spores, PM2.5, which includes car exhaust, factory smoke, and wildfire smoke, ultrafine particles, and ground-level ozone or smog. Breathing in these airborne pollutants can cause immediate negative health effects, including severe seasonal allergies and long-term breathing issues.

Indoor Sources of PM2.5 and Dust

Although a lot of the particulate matter that enters your home comes from the outside, there are a few ways it builds up from inside your living spaces too. These indoor pollution sources include aerosol cleaning products, wood-burning fireplaces, cigarette smoke, scented candles, and cooking oil smoke.

Air Pollution’s Destructive Impact on BC Houses

While polluted indoor air causes plenty of health issues, it can also cause hidden damage to your home ventilation ductwork and the structural integrity of your house or commercial business.

Over time, excess dust buildup in your property’s heating and cooling system can clog up your furnace ducts and force your furnace or heat pump to work overtime to circulate clean air—this means a much shorter lifespan for your HVAC system, unexpected furnace breakdowns, and much higher monthly energy bills. In areas with high outdoor dust and pollen levels, dust accumulation inside your home will be worse, which means the likelihood of a dirty, clogged air duct is also much higher.

High levels of outdoor air pollution combined with our wet coastal humidity can also increase the risk of toxic mold growth. Just like dust and pollen, mold spores can easily be tracked in from the outside on shoes or pets and spread through your house. In the right humid conditions, these spores can quickly grow and ruin porous indoor materials like drywall, area rugs, and wall-to-wall carpets. When it comes to getting rid of mold, the entire infestation must be safely removed to make sure the problem doesn’t return. As a rule of thumb, Canadian health guidelines recommend hiring a professional mold remediator for indoor mold growth larger than 10 square feet.
