Pollution levels have triggered a warning for Houston residents.
The environment ministry and Northern Health have issued an air quality advisory for the community due to high levels of fine particulate.
People with chronic medical conditions should postpone strenuous exercise until the advisory is lifted.
Those with heart or lung disease, diabetes as well as the elderly and infants are the most vulnerable to fine particulate exposure.
Woodstove use is banned within the District of Houston during the advisory unless it’s the only source of heat.
