Firewood Storage & Burning: Keep It Dry, Burn It Wisely
Good firewood can still perform badly if it is stored poorly or burned in the wrong conditions. Learn how to protect your wood, reduce smoke, maintain a safer burning system and get better heat from every load.
Dry wood. Good airflow. Maintained equipment.
Those basics improve combustion, reduce unnecessary smoke and help your stove or fireplace operate as intended.
Store firewood so air can move and water can’t linger
The goal is not to make your wood airtight. It is to keep the stack elevated, ventilated and protected from repeated wetting.
✓ Better storage habits
- Raise the stack above soil, grass and standing water using a suitable rack, pallet or base.
- Choose an open location with good airflow around the wood.
- Protect the top from prolonged rain and snow while keeping the sides ventilated where practical.
- Stack pieces securely and loosely enough for air to move between them.
- Keep newly delivered wood separate from older, ready-to-burn inventory when possible.
- Rotate older wood forward so it is used first.
× Storage habits to avoid
- Wrapping the entire pile tightly in plastic or a tarp with no ventilation.
- Stacking wood directly on wet ground.
- Putting wet or green wood into a closed, unventilated shed.
- Allowing leaves and debris to build up around the stack.
- Assuming a covered pile is dry without checking the wood itself.
- Ignoring local fire-safety requirements for where combustible materials may be stored.
Bring in what you need—not the whole woodpile
Indoor firewood storage should be convenient without creating unnecessary moisture, debris or combustible loading near the appliance.
Keep a modest supply
Bring in a practical amount for near-term use rather than storing a season’s worth inside the house.
Respect clearances
Keep firewood, baskets and kindling outside the clearance-to-combustibles required for your stove or fireplace.
Avoid wet wood indoors
Large quantities of wet firewood can release significant moisture into the home while they warm and dry.
Check before carrying
Knock off loose bark, snow and debris and inspect pieces before bringing them indoors.
A cleaner fire starts with dry fuel and enough air
Health Canada recommends taking steps to reduce wood-smoke exposure. Good fuel, proper operation and well-maintained equipment all contribute.
Good wood-burning habits
Your appliance manufacturer’s instructions come first. As general practice:
- Burn clean, dry, properly seasoned firewood suited to the appliance.
- Start fires with enough small dry fuel and airflow to establish a hot, active fire.
- Avoid long periods of smoky, smouldering combustion.
- Do not overload the firebox beyond the manufacturer’s instructions.
- Use the appliance’s air controls as designed rather than trying to “choke” a fire beyond safe operating guidance.
- Watch for changes in draft, smoke spillage, odours or appliance behaviour that may indicate maintenance is needed.
Wood heat needs working alarms and regular maintenance
Wood-burning appliances are fuel-burning systems. Smoke, chimney fires and carbon monoxide are serious hazards when equipment is poorly installed, operated or maintained.
Smoke alarms
Install and maintain smoke alarms as required by your local fire code. Test them regularly and replace units according to manufacturer guidance.
CO alarms
Health Canada recommends at least one carbon monoxide alarm in the home and proper maintenance of all fuel-burning appliances.
Annual inspection
Natural Resources Canada advises having solid-fuel-burning equipment and the chimney inspected annually and cleaned as often as necessary.
Professional help
Have installation, repairs and significant chimney/appliance concerns handled by a qualified professional and follow local requirements.
Your wood stove or fireplace is not a garbage incinerator
Burning inappropriate materials can create toxic smoke, damage equipment and increase deposits or fire risk.
Avoid burning:
Smoke and ash can carry contaminants
Health Canada specifically advises avoiding exposure to smoke or ash from burning treated wood. For normal residential wood burning, use clean firewood intended as fuel and follow your appliance instructions.
Cold-looking ashes can stay hot longer than you expect
Handle fireplace and wood-stove ash as if live embers may still be present.
Safer ash handling
- Allow the fire to burn down and follow your appliance instructions before removing ash.
- Use a non-combustible metal container with a tight-fitting lid.
- Keep the container outdoors and safely away from the house and other combustible materials.
- Allow ashes and embers to cool completely before final disposal.
Never assume ashes are cold
Ontario fire-safety guidance recommends letting wood-stove or fireplace ashes cool before placing them in a metal container with a tight-fitting lid and keeping that container outside away from combustible materials.
Check local rules before lighting a campfire or outdoor burn
Outdoor burning rules can change with municipality, season and wildfire conditions. A fire that is allowed one week may be prohibited during a restriction or fire ban.
Check your municipality
Local by-laws may regulate open-air burning, permits, setbacks, hours and acceptable fuels.
Watch restrictions
Fire bans and restricted fire zones can temporarily prohibit or limit outdoor fires during elevated wildfire risk.
Extinguish completely
Do not leave an outdoor fire unattended, and make sure all coals and embers are fully extinguished before leaving.
Less smoke is better for you and your neighbours
Health Canada identifies wood smoke as an indoor and outdoor air-quality concern. Cleaner burning starts with dry fuel, properly functioning equipment and sensible operating practices.
Burn dry fuel
Wet firewood tends to create cooler, smokier combustion and wastes energy evaporating moisture.
Maintain the system
Inspect and service your appliance, chimney and venting so smoke exits the home as designed.
Think about neighbours
Avoid unnecessary smoke and follow local nuisance, air-quality and burning restrictions where they apply.
Canadian safety resources
Use authoritative guidance for appliance safety, smoke exposure and local fire rules. Your appliance manual and local fire department remain important sources for your exact installation.

Should I cover my entire firewood pile?
Usually you want weather protection without trapping moisture. Protecting the top while allowing airflow around the sides is a common approach. Your exact setup should suit your climate and storage structure.
Can I stack firewood against my house?
CanFirewood does not recommend one universal setback because fire codes, insurance rules and property conditions differ. Keep bulk combustible storage away from ignition sources and follow local fire-safety requirements.
How much firewood should I keep indoors?
Keep a practical near-term supply while respecting appliance clearances and keeping exits and access paths open. Season the bulk of your firewood outdoors in a suitable ventilated location.
How often should my chimney be inspected?
Natural Resources Canada advises having solid-fuel-burning equipment and chimneys inspected annually and cleaned as often as necessary. Local requirements and appliance/chimney conditions may call for additional service.
Do I need a carbon monoxide alarm with a wood stove?
Health Canada recommends at least one carbon monoxide alarm in the home and regular maintenance of fuel-burning appliances. Follow provincial/local alarm requirements for your home.
Can I burn pressure-treated lumber?
No. Health Canada advises avoiding exposure to smoke and ash from burning treated wood. Burn only clean firewood intended for use as fuel.
Where should I put fireplace ashes?
Let them cool and place them in a covered metal container outdoors, safely away from the house and combustible materials. Treat ashes as potentially hot until they are completely cold.
Can I have a backyard fire anywhere in Ontario?
No. Local municipal rules, permits and provincial fire restrictions can apply. Check the rules and current fire conditions for the exact location before lighting an outdoor fire.
