Ties are broken by number of credentials (each Certified Arborist, Board Certified Master Arborist and Tree Risk Assessment Qualification holder counts, so someone with two counts twice), then Google reviews.
If the branches are dead or truly hazardous, then to protect your health and safety, it doesn't matter. Do it any time of the year. For live branches it is best done before the spring growth flush, when wounds close the fastest.
In Toronto you need a City permit to cut down or damage a private tree whose trunk is 30 cm or wider, measured 1.4 m off the ground. Every tree on a City street or boulevard is protected at any size, and ravine areas have their own stricter rules.
You need a permit to remove or injure a private tree with a trunk 30 cm or wider, measured 1.4 m off the ground. Since September 1, 2026, a stump 40 cm or wider can be used as proof the tree was protected.
Since September 1, 2026, healthy trees wider than 61 cm are 'Distinctive Trees'. The City can refuse a permit to remove or injure them.
If your property is inside a mapped ravine or natural feature area, you need a permit to remove or injure trees there, and to change the grade. Check the City's ravine by-law map before any work.
Any work that could harm or remove a City street tree, of any size, needs City permission. Call 311 for pruning or removal requests.
A tree whose trunk sits on the line belongs to both neighbours. Ontario’s Forestry Act says you need your neighbour’s consent before removing or injuring it.
In March 2026, City Council supported lowering the private tree size from 30 cm to 20 cm 'in principle'. This is not law yet; staff report back with a plan in 2027 (Council item 2026.IE27.8, adopted March 25–26, 2026).
Ask the municipality before any work starts. A good tree company will also check for you and tell you who applies for the permit.

They can help, but it is important to understand that they are not a cure-all. Having a gutter guard does not mean the gutters will never need to be inspected and cleared of leafs from time to time.
This is particularly the case when leafs get wet and accumulate. The leafs can sit on the gutter guard and act as a bridge, carrying the water right over the top of the gutter.
Tree work is dangerous, and it’s expensive to fix when it goes wrong. Six questions worth asking any company, including the ones on this page.
Tree work is one of the most dangerous jobs out there. We do our best on our end, but these certificates can change before we have a chance to update them. Some good companies will give them to you without you even having to ask. Bonus!
You may get a Certified Arborist as your salesperson, but will the same be true of the person who works on your property? You won't know until you ask. A Certified Arborist may cost more, but it can cost a lot more if the work is done wrong and the tree dies early or your property is damaged.
It should say exactly which trees, and whether cleanup, wood removal, stump grinding and so on are included. The more detailed the quote, the better.
If a bylaw applies, agree up front who applies for the permit and who pays the fee. Removing a protected tree without one usually means a fine for the property owner, not the tree company.
See if the work can be scheduled in a slower season for a lower price. Clear obstacles (fences, gates, lawn ornaments, plants) before the crew arrives. Find someone online, such as on Facebook Marketplace, who will take the wood for free. Or change the scope of work, for example pruning only the lower half of the tree instead of the whole tree.
If branches touch or come close to a hydro line, call your local hydro utility (the one on your electricity bill) first. Only crews the utility approves can work near power lines.
Both views have their pros and cons. In the winter an arborist can see the overall structure of the tree better. If there are splits in branches, we can see them more clearly. The downside is that sometimes it is a little harder to see which branches are dead or alive.
Bottom line: if you think your tree needs to be assessed, don't let the time of year stop you from reaching out to an arborist.
