Have you noticed a tree with no leaves while all the others around it are turning green, bark that’s peeling off, or mushrooms at the base of the trunk? A dead or dying tree is never a trivial matter, especially near a house, an entrance, or a high-traffic area. Here’s how to recognize the signs, understand the regulations in Quebec, and know exactly what to do.
Certain signs are easy to spot: a complete lack of leaves in the middle of the growing season, bark peeling off in patches, brittle branches that have lost their flexibility, or fungi (such as polypores) at the base of the trunk. These signs almost always indicate a dead tree or one in an advanced state of decay.
Others are more subtle: slowed growth year after year, sparse foliage on one side, visible cavities in the trunk. According to the Quebec government, municipalities can regulate tree removal to protect the urban forest canopy. Even a tree that is visibly dead does not always escape an administrative process before it is removed.

A dead tree gradually loses its structural strength. The roots decay, the wood becomes brittle, and the weight of the branches or trunk can cause them to fall without warning, especially during strong winds or ice storms. The risk affects people passing by as well as buildings, vehicles, and power lines.
And this risk increases over time. The longer a dead tree remains standing, the more its stability deteriorates, making it more difficult to remove as the situation evolves.
The answer depends on your municipality. In Montreal, for example, a permit is required to cut down a tree on private property, but one of the recognized grounds is precisely when the tree is dead or in a state of irreversible decline, its structure and stability are compromised, and it poses a risk of causing serious damage or endangering public safety. Each city has its own criteria and procedures. Checking with your local urban planning department is still the most reliable way to find out what applies to your situation.
Felling a dead tree is not something to be done on a whim. The weakened structure of the wood makes the cutting process more unpredictable than when felling a healthy tree, which increases the risks for the person performing the task and for the surrounding area. This task should therefore be entrusted to a team experienced in this type of work, which first assesses the direction of fall, the tree’s remaining stability, and the possible presence of power lines or nearby structures.
Once the tree has been felled, stump removal and branch chipping usually complete the job, leaving the site clean and safe.

Waiting for the tree to fall on its own before taking action is one such risk, and it increases the likelihood of damage or injury. Attempting to fell the tree yourself without assessing the trunk’s actual stability is another; this becomes dangerous very quickly once the wood has weakened.
Situation | What this means | What to Do |
A tree without leaves in the middle of the season | A likely sign of a dead or dying tree | Have the tree inspected by a professional team |
Mushrooms at the base of the trunk | Wood Decay Already Underway | A prompt evaluation is recommended |
Dead tree near a house or a driveway | Risk of falling, with possible injury | Schedule a professional tree removal as soon as possible |
A tree that has fallen or been uprooted after a storm | Emergency Situation | Contact an emergency tree care service |
Regularly inspecting your trees—especially after a harsh winter or a windstorm—helps you spot signs of decline before they become a hazard. Preventive pruning of fragile branches and bracing weakened trees can also extend the life of a tree that is not yet completely dead, when possible.
A dead tree is no cause for panic, but it does require prompt attention. Recognizing the signs, checking your municipality’s regulations, and having the situation assessed will allow you to take action at the right time—neither too early nor too late.
If you have any concerns about the condition of a tree on your property, our team at Arboxygène can assess it and guide you through the next steps, whether that involves pruning, bracing, or safe removal.
A diseased tree usually retains some of its foliage and can be treated. A dead tree no longer produces any leaves during the growing season and often has bark that peels off easily. A professional assessment can confirm this.
That’s often the case, but most municipalities in Quebec make an exception for dead or dangerous trees. The criteria vary from city to city, so you’ll still need to check with your local municipality.
There is no set timeframe, but the longer you wait, the more brittle the wood becomes and the greater the risk of it falling. A quick assessment can help determine how urgent the situation really is.
Yes, in some cases. If the tree died due to a disease or insect infestation, there is a risk that the problem could spread to neighboring trees. An assessment can help identify the cause and evaluate that risk.
Branches are usually shredded on site, and the trunk can be cut into sections or removed, depending on your needs. The stump can also be ground down to leave the area clean and safe.
