There’s been a cool edge to the air the last week or so. You may have noticed something else in the air, too — smoke. Unfortunately for those with health conditions like respiratory problems and heart disease, and for those who don’t want to develop them, two jurisdictions in the Cowichan Valley still allow at least some backyard burning, and wood burning appliances are still common everywhere in the Cowichan Valley Regional District. The Town of Ladysmith, City of Duncan and Town of Lake Cowichan have completely banned backyard burning. The Municipality of North Cowichan has cut back on what it allows, but there are still large swaths of territory within its boundaries where lighting up a burn pile is still allowed. … Cowichan’s transfer stations accept yard waste free of charge, so people can take their debris there instead of lighting it up. So consider your alternatives, and the people around you before you burn. Smoke travels.
