Under our Tree Protection Bylaw, the maintenance of trees on public property is the sole responsibility of The City. Our bylaw states that:
Cutting, removing, moving or pruning of The City of Calgary trees is prohibited unless City permission is granted.
Citizens cannot penetrate the bark or attach any object or sign to trees on City land.
Citzens cannot spray City trees with any substance except water.
Citizens cannot attach electrical cords or other objects to City trees.
Due to the variation in easment size accross the city property owners are encouraged to call 311 To determine if a tree is a City tree..

We recomend checking with local bylaws before work it conducted on any trees
City trees vs. private trees
"There are many City owned trees located on the front of residential lots. Some may not realize that a small strip behind the sidewalk or curb is City titled land.
This strip is referred to the City Utility Easement (CUE). The size of the area varies from lot to lot (0.5m to 5m). Any tree trunk located 50 per cent or more on the CUE is considered City owned. This means it is protected under the Parks by-law. The City is also responsible for any pruning, insect or disease control.
If you are unsure if trees on your property are City or privately owned please contact the Parks Department."
