EXCELLENT Based on 19 reviews Posted on Donna Campbell2025-09-27Trustindex verifies that the original source of the review is Google. EOA Inc has been caring for our Ash tree for years since the Ash Bore arrived in the area just East of Ottawa. We started treating our tree early in hopes of saving it. Today it is very large and healthy but had some larger, older branches that needed attention. Eastern Ontario Arborists has been our long term partner in maintaining this tree, They’re goal is to educate tree owners on the care of their tree and to save trees. I am pleased to recommend them.Posted on Robert Kendall2025-09-27Trustindex verifies that the original source of the review is Google. If you see a hearty and healthy White Ash tree in Queenswood Heights, it is probably ours, as most of the others are now sadly deceased. Dave and Sean at Eastern Ontario Arborists did it with a deft combination of deep root feeding, TreeAzen when needed and an occasional pep talk. R.

Our trees have never looked better.Posted on Richard Williams2025-09-19Trustindex verifies that the original source of the review is Google. We are very happy with the service we receive from Eastern Ontario Arborists. They have treated our ash tree for the emerald ash borer beatle for many years and it is doing really well. Also their attention and advice regarding pruning and care of the ash tree and our other trees is much appreciated. I'd recommend this firm to anyone.Posted on Jean Marc Melancon2025-09-03Trustindex verifies that the original source of the review is Google. Great company to deal with. Work was done in a very professional manner. The arborists were very respectful of my time and property and the property lines of my neighbors (received permission to cut some branches that crossed over property line). Arborists took time to explain the work that was done and answered all of my questions. I have to add that they were the most enthusiastic people I have met when it came to discussing and sharing knowledge on trees. Will definitely be my first choice for future work on my property.Posted on Ken Syer2025-09-03Trustindex verifies that the original source of the review is Google. We engaged your company to remove a tree which was sick and a hazard to our gazebo. Your team were professional and quick. We were quite impressed. Thank you.Posted on Ian Shackleton2025-08-29Trustindex verifies that the original source of the review is Google. Very pleased with the tree removal service they provided. Rates were very competitive, booking was prompt, and removal of a large elm in a tricky spot was done quickly yet safely. Would definitely use again and highly recommend.Posted on Helene Jubinville2025-08-29Trustindex verifies that the original source of the review is Google. Very professional. Sean took the time to explain why he was recommending a certain trim.Posted on Ron Armstrong2025-08-29Trustindex verifies that the original source of the review is Google. Recently we had Eastern Ontario Arborists back to our property to remove a dying tree. They got the necessary city permit and completed the work just as they had the two previous times that we had them work on other trees:on time, safely, quickly, with no damage to any property or plants and then fully cleaned up afterwards. We have one more tree that may need work in a decade and we will without any hesitation call them back again.Posted on Tom Keyserlingk2025-08-23Trustindex verifies that the original source of the review is Google. We interviewed many arborists and Dave came out in top due to his expertise and commitment to proper tree care. His team did an immaculate job of preserving our very large maple tree. His invoice even came in lower than quoted because the work was smaller than expected. You don’t see that very often. The team was exceptionally professional and really studied our tree before starting. terrific job!!Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
