If your property is located either entirely or partially within a ravine protected area, you may be required to apply to the City for a permit prior to undertaking any work that includes the injury or removal of a tree, placing or dumping fill or refuse, or altering the existing grade of land.
The Ravine and Natural Feature Protection By-law protects public and private natural areas that are vulnerable to degradation due to removal of trees or changes in grade.
You can use the Property Data Maps at Building Division Counters in each Planning District to determine if the Natural Feature Protection By-law applies to your proposed development. The applicant should have it marked on their survey or other plan drawn to a suitable scale of the site. This service costs $72.37 plus tax (subject to change) and can be requested of City of Toronto, Information and Technology, Geospatial Competency Centre, Map Service Counter, 18 Dyas Road, 4th Floor, Toronto M3B 1V5. Call 416-392-2506 or e-mail to email@example.com to arrange a suitable time for notation of the ravine limit on your survey.
Determine if the Natural Feature Protection By-law applies to your proposed development by using the Ravine and Natural Feature Protection By-law Map.
Applications will undergo preliminary review to determine their completeness but cannot be processed if incomplete.
If your proposed development requires Site Plan Approval or a Building Permit the application will be reviewed concurrently. Issuance of the permit will be made only after Site Plan Approval or conditional upon a Building Permit being issued.
In order to ensure acceptance of your application, please check this list to make sure your submission meets all City requirements as follows:
Please note that applications, which are incomplete due to a lack of, or inadequate information, cannot be processed.
All plans shall be prepared to the following specifications:

To remove, cut down or in any other way injure a tree to such an extent that it is deemed by the General Manager to be an imminently hazardous tree or is no longer viable and it becomes necessary to remove the tree.
Earth, sand, gravel, rubble, rubbish, garbage, or any other material whether similar to or different from any of these materials, whether originating on the site or elsewhere, used or capable of being used to raise, lower, or in any way, effect the contours of the ground.
A report that refers to soil stability and conditions related to erosion and/or slope instability, prepared by a Geotechnical Engineer, Geological Engineer, Hydrologist or related professional.
A defined elevation of land that has been established as a result of geologic, hydrologic, or other natural processes or by human alteration; that defines ravines, depressions, hills, stream channels, eskers and steepness of terrain.
A destabilized or structurally compromised tree that is in imminent danger of causing damage or injury to life or property.
Grade changes within areas that are regulated by the Toronto and Region Conservation Authority (TRCA). Urban Forestry will require evidence that TRCA has issued a permit.

Pruning of a tree in accordance with good arboricultural practice to maintain the health of the tree. Examples of reasons for such pruning include the following:
It may be detrimental to tree health to prune to reduce the shading effect of tree branches or to improve a view and such action is not acceptable under the City of Toronto tree by-laws.
Cultivation or tilling of garden beds as long as such work does not alter or create slopes at greater than 10 percent.
Placing of soil involving an amount of less than five cubic metres for the purposes of maintaining existing manicured areas.
