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 (RNFP) By-law protects public and private natural areas that are vulnerable to degradation due to removal of trees or changes in grade.
In the areas protected by the bylaw you may not, without a permit:
You can use the Property Data Maps at Building Division Counters in each Planning District or at the RNFP Counter to determine if the RNFP By-law applies to your proposed development.
Determine if the bylaw applies to your proposed development by using the RNFP 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 that are incomplete due to a lack of, or inadequate information, cannot be processed.
All plans shall be prepared to the following specifications:
Ensure that the RNFP line is drawn on all relevant plans.
The RNFP line can be downloaded for free online and imported into the plans. Alternately, the City can mark the RNFP line on a survey or other plans drawn to a suitable scale of the site for a fee. Request this service from the RNFP office at 416-392-2513 or firstname.lastname@example.org. For fees and more information, please visit the Ravine and Natural Feature Protection (RNFP) Line Certification section.
The Ravine and Natural Feature Protection (RNFP) Line Certification depicts the boundary of lands subject to provisions of the City of Toronto Municipal Code Chapter 658 – Ravine and Natural Feature Protection on a plan. This line must be drawn on all relevant plans that are submitted as part of any complete RNFP application.
If you have the ability to add the RNFP line on your site plan and/or survey accurately using Microstation, AutoCAD or other CAD/GIS software, this line can be downloaded for free online and imported into your plans.
You can download the Ravine and Natural Feature Protection line.
Import this data into your survey or site plan, transfer the line to your other relevant plans, and submit these plans with the RNFP line to the RNFP office for review.
If you are unable to add the published RNFP line on your site plan, we can provide this service for you.
You would be required to submit a site plan in DGN or DWG format to email@example.com.
The file must be in metric and to scale. Files that are in imperial or that are not to scale, will not be accepted.
The certified RNFP line would be returned to you in DGN, DWG and/or PDF formats.
If you do not have a digital file (DGN/DWG) and must submit a printed site plan, please provide a hard copy, not larger than 11″ x17″, on which we would mark the RNFP line.

A destabilized or structurally compromised tree that is in imminent danger of causing damage or injury to life or property.
Private trees that require removal due to construction of landscaping and structures accessory to a dwelling, including pools, are not considered as-of-right development. As a result, Urban Forestry is not obligated to issue a tree removal permit if such a structure is in conflict with by-law regulated trees and a permit to remove a tree may be denied by Urban Forestry in accordance with Municipal Code Chapter (MCC) 658 Ravine and Natural Feature Protection and MCC 813 Trees. If the permit is denied by Urban Forestry, the property owner may appeal the decision to City Council.

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.
