The Ministry of Environment and Parks in collaboration with the Northern Health Authority has issued an Air Quality Warning for Vanderhoof , Golden and Duncan due to elevated fine particulate matter. Exposure to fine particulate matter is particularly a concern for infants, older adults, individuals with chronic conditions (such as asthma, COPD, heart disease, and diabetes) or respiratory infections, and those who are pregnant. Postpone or reduce strenuous outdoor activities until the warning has ended. Spend time indoors in a space with filtered air. Monitor your symptoms and seek prompt medical attention if needed. Current conditions are expected to persist until weather conditions change and/or local emissions are reduced. The next update will be on November 2, 2026 and posted to the province’s Air Quality Warnings webpage: http://aqwarnings.gov.bc.ca Visit the provincial air quality data webpage for real-time observations: https://www2.gov.bc.ca/gov/content/environment/air-land-water/air/air-quality Actions you can take: Exposure to poor air quality can affect your health. Reduce the duration and intensity of outdoor activities. Spend time indoors in a space with filtered air. Some people are more likely to be negatively impacted by outdoor air pollution. This includes people with lung and heart conditions, pregnant individuals, infants and young children, people aged 65 and older, and anyone whose health is affected by a chronic condition or an acute illness. Follow your common sense: Stop or reduce your activity level if breathing becomes uncomfortable or you feel unwell. Always carry any rescue medications with you. Make sure that children and others who cannot care for themselves follow the same advice. Monitor your symptoms: Different people have different responses to elevated levels of air contaminants. Mild irritation and discomfort such as eye, nose and throat irritation, headaches or a mild cough are common, and usually disappear when the air contaminants return to typical levels. More serious but less common symptoms include wheezing, chest pains or severe cough. People with asthma or other chronic illness should follow any personal care plans designed with their family physicians. If you are unsure whether you need medical care, call HealthLink BC at 8-1-1. If you are experiencing difficulty in breathing, chest pain or discomfort, or a severe cough, contact your physician, walk-in clinic, or emergency department. If you are having a medical emergency, call 9-1-1. Tips to reduce your exposure to air pollution Air contaminant levels may be elevated indoors, so stay aware of your symptoms even when you are indoors. When indoors, keep windows and doors closed. Protect your indoor air from outdoor air pollution. Use a clean, good quality air filter in your ventilation system and/or a certified portable air cleaner that can filter fine particles. Avoid models that generate ozone, as these can produce harmful ozone concentrations indoors. Do-it-yourself air cleaners may also be used if other options are unavailable. For more details, see the BC Centre for Disease Control Do-it-yourself Air Cleaners fact sheet. If you must be outside, a well-constructed, well-fitting and properly worn respirator type mask (such as a NIOSH-certified N95 or equivalent respirator) can reduce your exposure to particulate matter. Even though exposure may be reduced, there can still be risks to health. When in a vehicle, keep windows closed with air set to recirculate. Emission reduction actions: Mandatory actions: Comply with the requirements of local woodstove bylaws that apply to periods when air quality advisories are in effect (e.g., City of Duncan and Municipality of North Cowichan). Facilities with air discharge authorizations under the Environmental Management Act are required to follow trigger actions within their permit related to Air Quality Warnings and are encouraged to reduce any other emissions where possible. Voluntary actions: Avoid using wood stoves and fireplaces unless it is the sole heating source. If wood burning is the sole heating source, burn dry, seasoned wood and ensure an adequate supply of combustion air. Reduce vehicle use where possible and avoid idling vehicles. Compost or mulch garden waste intead of burning it. Take public transit or carpool whenever possible. Visit https://www.airhealth.ca for information on how to reduce your health risk and your personal contribution to pollution levels, as well as for current and forecast AQHI values.

Between two updates a warning can appear, change or end without the page knowing: for a safety decision, open the official source.
Yellow asks for attention, orange for vigilance and precautions, and red signals an exceptional danger for which the instructions of the authorities must be followed. The details are in the section on levels higher up this page.
Is this page updated live?
No. It is rebuilt at every automatic update of the site, at least once a day, and shows the time of the last reading of the official source. For the exact situation right now, check Environment Canada.
Are these warnings official?
Yes. They are taken unchanged from the official source. This site produces neither warnings nor warning levels of its own.
