    Severe Weather Alerts - Kahnawake, Quebec

    • Smog Warning

      Smog Warning in effect until Wednesday, 4:34 PM EST. Source: Environment Canada

    Atmospheric conditions could result in a deterioration in air quality.

    Levels of air pollutants will be high beginning this evening and persisting until midday Wednesday.


    Smog especially affects asthmatic children and people with respiratory ailments or heart disease. It is therefore recommended that these individuals avoid intense physical activity outdoors until the smog warning is lifted.

    In Quebec, wood heating is the main source of fine particles that contribute to smog during winter. This activity generates the largest number of these particulates, more than industrial activities and transportation.
